4. Intended Purpose

The software mRay as a radiology instrument can be used by medical specialists for the visualization of image data. Image processing allows the calculation and visualization of healthy and abnormal tissues.

5. Intended Use

5.1. General

The patient group, for which mRay can be used, includes all patients from whom radiological image data has been created for the purpose of diagnosis or treatment. In a worst-case scenario the medical condition of the patient may be critical.

mRay can be operated in hospitals, medical practices, on the go or at home. The software is dedicated for mobile devices for fast and immediate access to radiologic images for informational purposes. When using mRay for diagnostic purposes, national regulations must be considered and an appropriate display must be used. mRay allows the display of images and data types that are defined by the Digital Imaging and Communications in Medicine (DICOM) standard (e.g. computed tomography (CT), magnetic resonance imaging (MRI), positron emission tomography (PET), fluoroscopy (XA), digital x-ray (CR), ultrasound (US)). The software offers common radiological software tools (e.g. windowing, measurements, thick slices and annotations).

Furthermore mRay is capable of performing image processing tasks such as finding, visualizing and quantifying anomalies in tissue. In particular the image analysis module mRay VEOcore may be used to perform an automated processing of brain images from imaging modalities such as CT, CT-Perfusion, or MRI including a Diffusion Weighted Imaging (DWI) Module. As a result, changes in contrast over time are visualized as colored perfusion maps, including flow related parameters and tissue blood volume quantification.

5.2. Contra-indications

mRay may not be used in Germany on a calibrated mobile device if reporting has to be performed for a x-Ray image (CR) or mammography (MG). Reporting may be performed on a regularly calibrated monitor ("Bildwiedergabegerät") with the mRay software.

5.3. Medical benefits

If mRay is used for viewing medical image data it can be used in the decision process for diagnosis and therapy. The following functionalities allow to do so.

To examine findings in CT images mRay Client is able to visualize images in accordance to the DICOM Grayscale Standard Display Function. By doing so a suitable mobile device is acting as a "Bildwiedergabesystem mit Befundqualität" in accordance with the DIN 6868-157. The constant availability of mobile devices results in time savings compared to stationary solutions.

The perfusion analysis of brain imaging data visualizes and quantifies tissue that is less supplied with blood (penumbra), oxygen deprived tissue caused by obstructed blood flow (core tissue) and the mismatch ratio between the two. The calculated values can be used to support decision making based on an assessment of the extent of tissue damage.

5.4. Warnings

mRay may not be used on a mobile device (tablet, smartphone or notebook) in a room containing a Magnet Resonanz Imaging (MRI) scanner.

5.4.1. Notes for use in diagnosis findings

For the use of mRay in the diagnostic context on mobile devices according to the German legal regulations (QSRL, DIN 6868-157), the instructions under the link must be followed: https://mbits.info/downloads/mRay-Nutzungsanweisungen_Befundung.pdf.

When operating mRay on a Windows PC or Mac, the image display system (BWS) must be calibrated and approved accordingly. Restrictions with regard to the modalities must then be derived from the BWS.

6. Introduction

In order to manage and configure the mRay server application, there are three software tools:

The mRay server application to start or restart the server, install a service, to set the port of the server through which clients communicate with the server and to install the license file.
The mRay Configuration application to configure the server and to manage data access, users and groups.
The mRay Gateway application allows to setup external access points for an mRay server without opening or forwarding ports in the internal network.

The following sections describe the individual functions of these applications.

7. Installation

The installation should be performed by an IT-administrator or a member of the mbits support staff.

7.1. Initial installation

This paragraph applies only to the Windows-installation.

Run the downloaded setup routine (named, for example, "mRayServer-6.1-win64-*.exe").

First Administrator rights are requested. Please note that the installation routine only needs those rights in order to install in the default folder 'C:\Program Files\mRay Server'. Please accept the dialog, no other modifications will be made to the system.

In the rest of the process, please follow the instructions of the installer program. During installation, the Visual Studio runtimes need to be installed, i.e. also on a newly installed server system all you have to install is contained in our installer package.

At the end of the installation the server application is automatically started and installed as a service.

7.2. Update

To perform an update just run the setup executable, which will detect any running mRay instances and ask you to close those. The existing data will not be deleted or overwritten. After the update is complete mRay Server will restart itself automatically.

New features require an update of your license file in order to be activated. Please consult the support of the installation.

7.2.1. Reinstallation / Future updates

In case of an update or a new installation, you can simply run the installer package (again). This will first try to uninstall the existing version (see Uninstall old version dialog). Afterwards, a normal installation is performed as described above. Note, however, that the uninstall process can delete existing data when requested. Please read the following subsection carefully.

Figure 1. Uninstall old version dialog

7.3. Uninstall

The uninstaller removes the currently installed version of the software. Please be nevertheless careful that you do not accidentally delete the existing data in this step unless you explicitly want to do so.

8. mRay server

The application mRay Server starts or stops the server process. In addition, a port can be set to under which the server is available. The server can be started as an ordinary application or automatically via a Windows service. We recommend to start the server via a service. This ensures that your server is restarted automatically in case of an unexpected system restart. Addtionally, no logon is required to restart the server. In a separate chapter 'Server Execution Models' you can learn more about the service installation process. The application can be seen in Server application dialog:

Figure 2. Server application dialog

Checkbox for starting or stopping the server process.
Configures the server communication port.
Starts the mRay Configuration application.
Opens the Admin Manual.
Shows the server version, the intended use and license terms.
You can switch between two different server execution models (application and service) over this button (more about that in chapter 'Server Execution Models').
With this button you can provide an SSL certificate, which is needed to use the mRay web client and the registration process for the upload service. This setting is only necessary if you are not using a gateway and still want to use the above functions. For the SSL certificate the following criteria must be met.

9. License installation

To use mRay Server without any restrictions you need to obtain a license and activate it via the mRay server configuration. You can get a license by contacting your contractor. The following steps are required to do an activation:

Figure 3. Product license registration dialog

Figure 4. About dialog

Run the newly installed mRay server application.
A popup appears (see Product license registration dialog) which prompts you to install a license. It also shows you additional information such as:
- License status: Displays how long your license is valid.
- Registration key: This key needs to be submitted to your contractor to obtain an activation key.
Now it is time to get in contact with your contractor and to send him your registration key. After he has received your key, he will send you back an activation key.
Now go back to the mRay Server application window and click the' Configuration' button.
The mRay Server configuration opens. Now log on to the server with the "admin" account via the configuration. Please note the server text field, which specifies the target address of the server to which you want to connect and install the license. In the case of a remote license installation, this field may need to be edited.
After successful login please click on the "About this mRay server" button, which opens a dialog with the title bar "About mRay". This allows you to install a license (see About dialog).
With the reception of your activation key you are ready to activate the server by installing it via the 'Select license file' button. When you click on the button a file explorer opens which prompts you to input the path to your license file.
If the license file is valid you can now proceed to start and configure your server. If not, the mRay server application automatically closes and you will be prompted again to install a license after you restarted the mRay server application.

The same procedure is valid for a reactivation of your license which is needed in case of a license prolongation or a booking of additional modules. Since you are not prompted automatically again to activate your server, you need to open the reactivation dialog manually. You can access it via the "About" dialog of the mRay Server configuration. To do this, click on the "About" button after you have logged in as "admin" via the configuration on the server. Please click on the button labeled 'Change license'. Now, the activation dialog explained previously opens again. From there you can proceed with the steps described in the last section.

10. Server execution models

There are two different execution models of the server. The first one is to execute the server as an ordinary application. To run the server in this mode two requirements need to be met: You need to keep the mRay server application window open and the checkbox 'start on port' must be checked. A disadvantage of this execution model is that the server will get and be kept deactivated if the mRay server application is closed accidentally or the system restarts unexpectedly unless the server is restarted again manually.

The second execution model is to install the server as a service. With this model you do not need to keep the mRay server application window open and the server restarts automatically if the system restarts. Furthermore a login at the logon screen is not required.

To switch between both modes you can to click on the button labeled 'Install as service' or 'Uninstall service' within the mRay server application. 'Install as service' installs the service as a service application (second mode) whereas 'Uninstall service' runs the server as an ordinary application (first mode). The button labeling is alternating.

A service is not allowed to access a network drive unless the affected host system (computer name) is listed in the ACL (access control list) of the network drive. An alternative is to run the service under a different account as opposed to the LocalSystem account which is authorized to access the network drive. Please ensure that the account has full access to the application data of mRay (C:\ProgramData\MBITS\mRayServer) and to all of the registered folders in the configuration.

11. mRay Gateway

The mRay gateway offers a connection forwarding for mRay clients to a mRay server where the clients may have no direct access to the mRay server itself e.g. if you are running your mRay server in a closed network.

In order to install the gateway application, run the mRayGateway-*-win64.exe and follow the install programs instructions.Wait until the installation process has completed and run the gateway application.

Figure 5. Gateway window

The gateway launcher offers a small user interface to configure the application.

Run gateway: Toggle to run or stop the gateway process.
Client port: The port used by mRay clients to connect to the gateway.
Server port: The port used by the mRay server to connect to the gateway.
Install as service: Installs the mRay gateway as a Windows service.
Use SSL: Activates SSL connections, which are required to use the mRay Web Client and the registration process for the upload service. This requires an SSL certificate and a private key for your public DNS under which your mRay gateway can be reached.
SSL certificate: The path to your SSL certificate, issued for your public DNS under which your mRay gateway can be reached.
SSL key: The path to your private SSL key issued to your public DNS under which your mRay Gateway is accessible.
Passphrase (optional): Password to your private key, if it is password protected.

The certificate must meet the following criteria:

The SSL certificate must be issued by an official certification authority (CA) for any browser to accept or trust it
The SSL certificate must not be self-signed
The SSL certificate must be in PEM format or ASCII Base64 encoded

To connect your mRay server to the gateway installation, enter the address of the gateway with the port of the gateway in the mRay configuration like it is shown in General Settings (see Configuration settings).

12. mRay Configuration

The mRay Configuration application is used to manage the server system (see Configuration status). You can change general settings, pool, users, groups and monitor the server process. Please log in with an administrator user in order to make adjustments.

12.1. Connection window

The connection window (see Configuration status) is used to connect to the server:

Figure 6. Configuration status

Enter your administrator login name (default name is 'admin' ) here.
Specify the administrator password that you received by your mbits contact. The password should be changed after the first login.
If everything is correct, you can connect to the server using the Connect button.

12.2. Configuration window

The Home screen (see Configuration connection section) contains the general configuration tabs, which are explained in the following sections:

Figure 7. Configuration connection section

Status: Displays the current status of the server and other internal information.
Settings: Make general, globally applicable settings to the server.
E-mail SMTP: Here you can set up an outgoing e-mail server (SMTP) to send important messages via e-mail from mRay Server (e. g. PIN messages, expiring licenses, etc.).
Pools: A Pool corresponds to a DICOM node on the network. Pools contain user access rights for different data sources.
Users: Create, manage and delete users.
Groups: Create user access and chat groups.
Log: Displays the server log.
Advanced: You can adjust advanced settings here.

12.3. Status tab

The Status tab (see Configuration status with PIN information) shows license information, free space on the server and other internal information:

Figure 8. Configuration status with PIN information

Shows the users PIN’s here if LDAP is active.
Opens the About dialog for the connected server that displays information about the manufacturer, used licenses, certification, etc. for the product and allows you to install updates or a license.
Opens the report generation dialog (see Generate statistics).
Activating the checkbox displays additional internal information of the server process.
Activating the checkbox pauses the information pane to be updated continuously.

13. General settings

This tab can be used to change various global settings (see Configuration settings).

Figure 9. Configuration settings

If checked the server can also be configured from a remote computer. Note: If your server is reachable from the internet, choosing this option will enable server configuration from any computer. Pay attention to provide a strong administrator password (min. 8 characters with uppercase and lowercase characters and numbers).
This checkbox activates the automatic deletion of the oldest records if the free memory falls under the provided limit on the installation disk. This ensures that the server is always ready for use. Please note that no data will be deleted from the PACS or similar, only the cached and encrypted DICOM data of the mRay server will be removed.
Specifies the desired free space in gigabytes if automatic deletion is activated.
If checked, the server uses an alternate working mRay path to store data like the cached and encrypted DICOM files there.
Set the alternate working folder. If enabled, the application data of newly created pools are stored within that path.
Choose which devices of a user do instantly get access without permission of the administrator.
If checked the server will connect to the gateway URL given in the input field. Input field: Set the address of the mRay Gateway installation the mRay Server should connect to. Make sure that the specified URL includes the port of the gateway. If you want your mRay Server to connect to multiple gateways you can specify their addresses by using a semicolon as a separator. For example: demo.mray.info:35000 or heidelberg.mbits.info:34999;test.mray.info:35001
If enabled, set the settings for the LDAP connection.
Fill in your IP address or server URL in this input field. If the server needs to be contacted via a special port you need to append a colon followed by the port. For example: ad.mbits.info:40000 bzw. 192.168.1.100:40000
Fill in the domain which contains the users and groups. This input field is optional. If it is empty, the domain will be requested from the LDAP server. By setting the option "LDAP - Domain is DN" unequal 0 in the advanced options the fully qualified domain needs to be specified (e.g. dc=ad,dc=example,dc=com).
Insert your username here (optional in case of an anonymous login). By setting the options "LDAP - Username is DN" and/or "LDAP - Domain is DN" unequal 0 in the advanced options the fully qualified username needs to be specified. (e.g. cn=ldapuser,dc=ad,dc=example,dc=com).
Insert your password here.
Here you can input the time interval to synchronize with the LDAP server.
Press this button to synchronize the LDAP server immediately. Please note that all changes within the settings will be applied.
Shows the current synchronization state.
Here you can choose, which groups and their users will be stored in the user and groups directory of the mRay server.
With this input field you can search for special groups.
Apply the changed settings. Note: Changes to the fields 1-7 must always be confirmed with this button.
Revert the changed settings.

For the integration scenario 'mRay server with worldwide access' you can configure the server worldwide with the mRay configuration and internet access. Please be cautious to use a strong administrator password (at least 8 characters, upper/lower case and digits).

Please note that if you have activated the LDAP synchronization (see point 8), you must also configure an existing sender e-mail account (see chapter Email SMTP). This is required to send an automatic PIN notification to an mRay LDAP user to be authenticated if requested. A new PIN request is usually made in the case of a first authentication or a password change.

The expire time of a PIN that is requested by an LDAP user can be manually set using the Advanced options using the 'LDAP - Time after PIN expires' setting.

Changes need to be confirmed before they are applied.

14. Pool management

The Pool Tab (Pool list) lets you create, edit and delete „pools“:

Figure 10. Pool list

Adds a new pool.
„Edit“ or double clicking a pool will open the edit dialog.
Deletes the selected pool.
Filter the pool list using free text.
This button will only be shown if your license includes the PACS upload feature. This features enables structured reports, presentation states and photos to be stored in a PACS. Push this button to open the PACS Upload Pool settings. You can enter your PACS address, port and AET in the dialog. Note that you may need to enter the upload pool as a DICOM send entity in your PACS (depending on the PACS software).
Press this button to edit the share pool settings. This pool is used to host shared data. If your license doesn’t include the PACS upoad feature then all datasets created on client devices (i.e. structured reports, presentation states and photos) will be stored in this pool. Otherwise only internally shared presentation states will be stored in the share pool.

There are three different types of pools: Network Nodes, Query/Retrieve pools and External DICOM Folders.

14.1. Network node pool

A Network node pool is equivalent to a regular DICOM node (see Network node pool configuration).

Figure 11. Network node pool configuration

Select which type of pool you want to create:
- Network node: Represents an ordinary PACS node to which you can send data from a PACS.
- Query/Retrieve: Represents a pool with which you can send search queries to a PACS.
- External DICOM folder: Access to an abitrary folder.
Specify a name for the pool. The checkbox lets you activate or deactivate the pool (without deleting it).
If activated, a different working path for the new pool can be specified where all data is stored. This will overwrite the general setting on the working path (if set). Please note, however, that the settings concerning free space and limits will apply to that path.
Enables a DICOM C-Store SCP listener through which you can send DICOM data from your PACS to your pool. A TCP input port and an application entity title (AET) for the DICOM C-Store SCP listener must be set for this pool.
- Please note: You have to add the specified AET and port of the mRay server to your PACS configuration. Otherwise you will not be able to send images to mRay.
- A possible connection error while sending image data from a PACS workstation to the mRay server, cannot be detected by mRay.
Activates the temporary storage of already retrieved or transmitted datasets, which speeds up a later search for these datasets. When this option is activated, new incoming datasets are not automatically placed in the user’s inbox, but must first be moved to the inbox via the search tab.
Delete incoming datasets from the server after the specified number of days. You can also enter floating-point numbers (e.g. „2.5“).
Let’s you specify how long local data on the client app will be available.
Activates/deactivates the “auto download” feature. If enabled here and in the client app, incoming datasets will automatically be downloaded to the client app.
Activates/ deactivates JPEG Compression for this pool.
The mRay server can optionally remove patient information from incoming image data (“Pseudonymization”). Warning

Burned-in information cannot be removed. Please ensure, that there is no personal information directly encoded in your images when using this feature.

JPEG compression is only supported for images with maximum 12 bits and lossless compression is only supported for images with maximum 16 bits.

14.2. Query/Retrieve pool

A Query/Retrieve Pool is created to search a PACS from within the client app (see Query/Retrieve pool configuration).

Figure 12. Query/Retrieve pool configuration

Any function already described in 'Network Node Pool' will not be explained. These are the different form fields to consider:

Specify first the local port and the AET for the mRay server (i.e. the AET which will receive answers from your PACS). On the second line specify the connection details of your PACS. Status field containing potential errors. Creates the pool. Abort Creation of the pool. Notice You have to add the specified AET and port of the mRay server to your PACS configuration. Otherwise the connection will not be accepted by your PACS.

14.3. External DICOM folder pool

An external DICOM folder (see External DICOM pool configuration) imports dicom data from a local directory.

Figure 13. External DICOM pool configuration

All other fields are explained in chapter 'Network node pool'.

Specify the external directory containing DICOM data here. Info The external DICOM folder pool also supports non DICOM file types i.e. PDF, PNG, JPG, TIFF, TGA and BMP

14.4. User Storage

The pool type User Storage (see User Storage configuration) serves as target storage for uploaded data via the upload service.

Figure 14. User Storage configuration

If not described in detail, the data fields have already been explained before.

15. User management

The Users tab lets you add, edit and delete users (User list).

Name: Complete name of the user (will be shown to others in chat-rooms).
Set password: Enter and confirm the password for the user.
Add user / Apply changes: Creates the user with the configured properties or adds the user if it does not exist yet, or saves all changes made to the user.
Cancel: Cancels the creation of the user or discards all changes.
Enabled: Enables or disables the user (Disabled users can not connect to the server).
Mail: Alternate e-mail address(es). Will be preferred against LDAP mail (see point 18) in case of e-mail notifications. You can use the semicolon separator (;) to specify multiple e-mail addresses.
External ID: DN (short: distinguished name), i.e. unique identifier within the LDAP directory, of the synchronized LDAP user.
LDAP-Mail: LDAP synchronized e-mail address of an LDAP user. Is used for the automatic dispatch of important e-mail notifications from mRay. Can be overwritten by an alternative e-mail address (see item 16).
Require new PIN: Triggers a new PIN request for a user, so that the most recent LDAP password is queried again (for example, in case of password change).
Alternative ID: If a change is made in the Active Directory, e.g. the user moves to another subtree, this field can be used as an additional identification key to identify the user in addition to the DN. A unique LDAP attribute should be used, which does not change over the life cycle of the user (example: objectSid).

For LDAP users, the data and state is synchronized with your Active Directory and therefore cannot be changed via the user interface. For this reason some of the input fields are grayed out or disabled.

Please take care of the characters used for the password as they might not be available on the keyboard of a mobile device.

Manual users can still be maintained and used alongside LDAP synchronized users.
