mRay allows medical professionals to view and evaluate radiological images. Main users are physicians. 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.
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 within the European Union 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), digitalx-ray (CR), ultrasound (US)). The software offers common radiological software tools (e.g. windowing, measurements, thick slices and annotations).
mRay is a mobile viewer application for radiological images. It supports DICOM image files as well as other common image formats and PDF files. The the major functions of use are:
The welcome screen appears as soon as the application has been started (Figure 1). You can connect to Demo Server with the button. Additional text fields for username and password appear after the user has specified a server address. If the login data is correct you will be directed to the main screen of the application. Please contact your administrator to get the server address and your login credentials. Enter your login credentials to log in.
A PIN check will be neccesarry when logging in with an ActiveDirectory account for the first time. The PIN will be send to the mail address registered in your ActiveDirectory account. The keyboard can be opened by tapping on the input field (2 Figure 1.1). The PIN will be validated immerdiantly after entering the sixth digit.
The PIN dialog features the following UI elements:
The inbox will be opened after logging in (Figure 2). With this you can browse and select the wanted DICOM files, which are enabled for you through the server. Thus you can see all files on the mRay server on which you have access rights.
The following functions are available on this screen:
Swipe up/down to scroll through lists or use the scrollbar on the right of a list to navigate quickly through them.
By swiping right within a list container you are able to hide single study or series. Those won't appear in the list anymore. To view hidden datasets you need to click the button 'show hidden datasets' in the settings. Hide all data at once by executing the gesture with three fingers at the same time.
By clicking a study in the inbox you will get to the series selection (Figure 4).
The following functions are available:
If the messaging function is enabled you are able to share a series by clicking and holding it for a while (Figure 5).
The main menu will be opened after clicking the mRay logo (Figure 6).
The following functions are available:
On this screen you can adjust your settings just as you want (Figure 7).
The following functions are available:
By using the 'Change password' screen you are able to change your personal account password, without contacting your admin. The following figures will visualize the procedure
The following items will show you the functionality of this screen:
Please take care that you are able to type all the special characters via your touch devices, if you want to use special characters in your password. Otherwise you have no opportunity to log in. If you use special characters by a mistake and are not able to log in anymore, please contact your admin to reset your password.
This routine is used to calibrate your display to be in accordance with the DICOM Standard Display Function (GSDF). You need a luminance measuring device to perform the routine. The routine consists of displaying the image of the TG18 group. Measure the luminance of the displayed square (1) and enter the value with either (6), (2) or (3). Click 'Accept' to proceed to next image / step. After all TG18 images have been processed the calibration results will be stored and applied to the visualization of images.
The following points need to be checked before the test:
With the Secondary Capture feature you are able to take a photo with your mobile device camera. This feature was designed for wound documentation for example. By saving a photo it will be uploaded to the PACS if your server license does include this feature. The photo will be added as a new study to the inbox. The button to take a Secondary Capture photo is viewed in the lower right corner of the inbox as a camera icon and will lead you directly to the camera view. Taking a photo will show the following window as you can see in Figure 10. Saved photos will not appear in your devices gallery and are only stored internally in mRay on your device.
For adding more than one photo for a single patient you can use the buton (1) shown in the following figure to recall the information of the previous image. To add photos to an existing study just ensure the study description is the same as the study where the new photo should be added.
Although it is possible to use measurement tools on Secondary Capture photos, please notice that the values you'll get returned are probably wrong.
With the messaging function (Figure 12) you are able to send and recieve messages and datasets/key images to your contacts and groups.
The screen provides the following functions:
Just as known from other messaging applications it is possible to send and recieve messages (Figure 13). Additionally it is possible to share series, key images and sending audio messages.
This screen provides the following functions:
In addition to text, pictures can also be sent to contacts. This is possible by clicking on the photo camera icon, which is to the left of the text field (see Figure 14).
The above figures illustrate the following functions:
In the case of photo messages, there is no access to the private photo memory or the gallery of the device. The photos are only managed and stored internally by and within mRay.
Additionally to text messages you can also send audio messages. Simply click the microphone button, which is located at the opposide of the input field on the chat screen (see Figure 16).
The upper figure visualizes the following functions:
mRay informs users about new datasets and messages. These notifications will appear in the center of the upper edge on the screen when the application is opened, or as a system notification (just like recieving a SMS, see Figure 19) when the application is running in background (Figure 18, Item 1). The number of new arrived datasets and messages will be displayed as badges on the corresponding tab symbols of the inbox and the messenger (see Figure 19). You may change the types of notifications in the settings menu.
By clicking the notification you will open the application which will switch automatically to the relevant spot (for example to the messages).
The notifications do not contain patient data or contents of messages to provide protection and privacy as good as possible.
With the query/retrieve function you are able to search for contents directly in a PACS (Figure 20).
mRay sends your entries to the PACS. You can use so called wildcards (*/?) just as you are used to it in your usual PACS environment. Only the name field appends the wildcard sign '*' as a default. If you don't make any specification the field will be ignored at a query.
The following functions are available on this screen:
In certain circumstances there are some extra input fields visible. For more information please contact your administrator.
In the query results view there will be all patients enumerated, which have a match with your query (Figure 21).
This view provides the following functions:
In the favorites tab your bookmarked datasets will be enumerated. They will be viewed just like in the patient list. You can also remove them from your favorites (see chapter Inbox).
Selecting a series will open the viewer.
The following functionality is available:
The series- and key image buttons only appear when there is another series or keyimage for the current series (Figure 23).
The Interactionbar offers tools and functionality to interact with the currently open image (Figure 24). It contains a toolmenu button (1) and a scrollwheel (2) to navigate trought 3D datasets. The toolmenu button shows the currently selected tool.
The scrollwheel allows you to scroll trought a series image layers. You can interact with the scrollwheel by tapping the arrow keys for next / previous slice or scrolling the wheel with your finger. By releasing the wheel it will instantly stop.
The Scrollbar (Figure 25 #1) allows you to change the currently viewed image slice, like the scrollwheel. In difference to the scrollwhel, the scrollbar's layout instantly indicates where you are in the image slice stack. Depending on your view rotation, the scrollbars top/bottom or left/right edge symbolize the beginning/end of the dataset. There are two different scrolling modes:
The MPR views allow you to open up multiple views at once (Figure 26). Following screenshots show the MPR view:
The Screenshot shows the original view of a dataset, the locally computet reconstructions (MPRs) and information to the viewed dataset.
You can change the perspective with the MPR perspective button (Figure 26, Point 1). This allows you to switch between the different modailitys and a 3D reconstruction. The buttons in the top right corner (Figure 26, Point 2), allows you to open or close a view. If there is more than one view, a button to synchronize view adjustments will appear.
The 3D reconstruction shows planes of the currenlty open views. This view will only contain contents if there is at least one open MPR view. Smartphones can only open up to 2 views and can not use the 3D reconstruction.
In order to interact with a view you have to select the appropriate view first. In order to do so, just tap on the view. The selcted view is marked by an orange border.
mRay allows you to load different datasets in different views. After opening a new view, you can open another series by tapping on the inbox button. It is also possible to view two different patients at the same time. To prevent a confusion between different patients a permanent warning is shown.
You can select the following tools from the toolmenu (Figure 27):
The currently selected tool is saved across studies.
mRay allows you to create presets for the Level-Window tool. These can be selected from the Level-Window menu (Figure 28, right: In editmode). Please note: These presets are saved to the device and are not synced to other devices.
The following button (Figure 30) will appear in the toolmenu if the user has created any annotations.
The note tool creates text notes in the current slice image (Figure 32). Notes can be edited by double tapping on them. Notes can be selected by tapping on them or selecting them in the annotation list, like measurements. You can move the selected Note with one finger. You can delete notes and measurements from the annotations menu.
The measurement tool allows you to create measurements on an image slice. The display length is rounded to one digit after the comma. The inserted measurement (Figure 33) can be adjusted by 'Pinch-to-Zoom'. Alternatively you can adjust booth ends separately. In order to do so you have to tap on the transparent circles at the end of the line. You can create as much measurements as you want in one image. You can reselect a measurement by tapping on it or selecting it from the 'List of annotation' window.
The measurement information is read out the data send by the PACS. Missing or corrupted spacing data could lead to wrong measurments. Should you encounter problems with wrong measurements there could be an issue in the modality setup of the image data. Please consult the appropriate IT-Support.
In 2D-radiographs the measurements show the size like it would be shown by the X-ray detector. Keep in mind that measurements show the size of the projection and not the physical size of a structure! This also applies to the 'REAL' zoom mode!
The angle tools allows you to create an angle in the current image slice (Figure 34). The angles lines are adjustable in their length and direction so that you can modify the angly by your needs. You can move the whole angle by tap and hold the intercept point. The angle can be deleted from the annotation menu.
Beside the normal angle tool there is the remote angle. While the normal angle is a real angle, the remote angle calculates the angle between two lines without a crossing point. Beside that, it can be used like the normal angle tool.
With the 'Region of interest' feature in the toolmenu you are able to add a region of interest (short: ROI) to an image or a slice (Figure 36). After adding a ROI it is activated by default and ready for individualization. The ROI can be moved by tapping the cross in the middle of it and dragging it around. By using the two touch handles (white, transparent circles at the edge of the ROI) you are able to shape and rotate the ROI. On the opposide of the touch handles you'll find the following information:
If your server license includes the structured reporting feature then your are abel to create textual report within mRay. By tapping the 'create report' button in the toolmenu you are able to create a DICOM Structured Report, which will be added to the current study and saved to the PACS (if the PACS upload feature is included in your server license). See (Figure 37)
You can reopen the minimized input window by pushing button (1) in the interaction bar.
The list of known issues leads to problems identified after the release of the latest version of mRay. These problems, however, were classified as non-critical, so that an unrestricted working with the application is possible.
