Radiological image viewer for mobile devices with image processing functions
Release-Date: September 2018
© 2018 mbits imaging GmbH
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:
By cicking a series it will be downloaded (if it's not already downloaded) and opened for viewing.
Use the barcode scanner to quickly and easily insert patient IDs into text fields. This function is available in various text fields, such as the search for the patient ID. Hold the camera image over the barcode and make sure that the
entire barcode is in the marked area. If the barcode has been recognized, the text is automatically transferred to the text field.
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.
Due to the measurement method, the recorded values are only an approximation of the actual lux value and thus the room class.
The figure shows the individual test pattern elements. The following points must be checked in detail (according to the standard):
The photo documentation feature is expressly not permitted for diagnosis or treament decisions.
This feature isn't enabled by default. It is only avaible for evalution purposes. If you're interested in taking part of the evaluation, please conctact your mbits support staff.
When the feature is enabled for the current user you'll see an extra tab for the photo documentation and a button in your inbox to open the camera.
By pressing on the camera button (Point 2) you'll open the camera and be able to capture all the photos you require. A photo documentation workflow will be like the following
When you've captured all the photos you need press the the photo stack (Point 2) to continue to the review process.
The review gallery displays all the photos that you have taken so far ordered by their capture date.
Be careful and do not delete images by accident. Deleted images can not be restored.
If you want to inspect an image more detailed you can enter the photo view by clicking the target photo. Inside the photoview you get a fullscreen overview of the image. In this mode you can perform all the transform operations that are
already known from the regular viewer (panning, zoom). By clicking the next or previous (Point 2) button you can navigate between the images.
Be careful and do not delete images by accident. Deleted images can not be restored.
In the next step you are asked to to select a bodypart to which the selected photogroup belongs to. The selected bodypart defaults to "Unspecified" and is displayed in a label (Point 4). To select a bodypart just press on the human. To
switch between front and back view you can press the corresponding button (Point 2). For navigation purposes you it's displayed which side is left or right (Point 3).
By tapping on the next button you will continue to the orderview.
In this page all patients and unprocessed orders are displayed. Each order/patient are displayed with the necessary information to identify them (Point 1). To filter all the entries you can use the search field in the top (Point 3). To
scan a QR or Barcode you can use the corresponding button below the search field (Point 4).
By clicking an order/patient you'll proceed to the confirm. If there is no order and no patient that fits your case you'll want to add the patient manually with the add patient button (Number).
If you have decided to manually add the desired patient, the following view will open. The required tags for the patient are displayed at Point 1 and setup by your pacs administrator. Make sure to enter the correct information before proceeding
to the next step.
In this step you have the ability to review your assigned photos one last time and to add additional tags to the order that can help with identifying the order at a later stage. (The keywording must be configured at the server to be available,
please contact your administrator or mbits support)
This view is the default view when you press the photo documentation tab in the top. It is an overview that lists all unassigned photos, pending orders and completed orders. By pressing the unassigned photos (Point 1) you'll proceed into
the review gallery where you can assign those photos like already described above. The list of pending orders (Point 1) are the orders that have not yet been confirmed by the server. This can be caused by no internet connection or
that the server is still processing those orders. The completed list (Point 2) shows all orders that are known to be completly processed. By pressing the "Clear completed" button (Point 3) those orders are not shown anymore to you.
With the messaging function (Figure 24) 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 25). 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 26).
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 28).
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 31) when the application is running in background (Figure 30, 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 29). 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 search function you can search the database of your mRay server quickly and easily. The results list shows records matching your search criteria. The search results can be moved to the inbox using the Download button. You can also view records directly in the search or simply share them with a colleague. Note that, of course, only those records appear that you have been granted access rights to. If the desired data record does not appear in the list, it is possible to make a corresponding request via one or more connected PACS. The search fields can also be customized to suit your needs.
The search fields can be customized and the following fields are available for selection:
mRay forwards your input to your PACS. So if you want to use so-called wildcards (*/?), you can do the same as from your usual PACS environment. Only the wildcard character "*" is appended to the name field by default. If you do not make
an entry, the field is ignored during the query.
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.
The Interactionbar offers tools and functionality to interact with the currently open image (Figure 36). 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 37) 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 38). 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 (Point 1). This allows you to switch between the different modailitys and a 3D reconstruction. The buttons in the top right corner (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 39):
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 40, right: In editmode). Please note: These presets are saved to the device and are not synced to other devices.
The following button (Figure 42) will appear in the toolmenu if the user has created any annotations.
The note tool creates text notes in the current slice image. 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 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. 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.
You can use the "Segmentation"tool to insert a manual segmentation into a layered image. After activating, circle the object to be segmented with your finger. The annotation can then be adjusted. The segmentation points can be easily moved or deleted with double tap. New points can be added by' +'. On the side of the segmentation there is an additional information text which contains the following calculated values for the pixels in the segmentation:
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. 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).
You can reopen the minimized input window by pushing button (1) in the interaction bar.
mRay supports the display of DICOM files with up to 16 overlay masks. These overlays can be switched on and off separately via a menu in the viewer. It is also possible to assign a freely selectable color and transparency to each overlay.
mRay supports the integration of the VeoCore software. The system can be used for automatic analysis of stroke regions in perfusion datasets. For detailed instructions refer to the VeoCore manual.
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.
