Basic Image Review (BIR) Connectathon Tests

Transcription

1 Basic Image eview (BI) Connectathon Tests General Instructions The tests in this document are applicable to two different IHE actors: 1) An Image Display actor in the Basic Image eview (BI) Integration Profile. This actor has specific functional requirements for its viewer application, but no performance requirements. It performs all tests in this document prefaced by BI_. It should skip tests with PDI_. At the Connectathon, these tests are run on a hardware/software platform provided by the Image Display vendor. 2) A Portable Media Creator (PMC) actor that supports the Basic Viewer option in the Portable Data for Imaging (PDI) Integration Profile encodes a Basic Viewer application on the PDI media it creates. This Basic Viewer has all of the functional requirements of the BI Image Display actor; these requirements are applicable in two different hardware/software environments (see next section). It also has performance requirements tied to a specific hardware platform. It performs all tests in this document prefaced by PDI_ and those with BI_. At the Connectathon, these tests are run on controlled hardware/software platforms provided by the Connectathon Managers using the PDI media created by the Portable Media Creator. For the evaluator (connectathon monitor): When testing a BI/Image Display, the test image set used within these tests are query/retrievable from the Connectathon Central Archive, and also stored on a PDI CD. The BI/Image Display should pre-load these prior to evaluation beginning. When these tests are run for a PDI/Portable Media Creator supporting the Basic Viewer (ie the viewer is encoded on PDI media), we want the PMC to create media containing the test image set, if possible. If the system can only create media with its own images, the evaluator may not be able to perform all functions. Use a single-button mouse, or, on a multi-button mouse, perform all tests with left mouse button only. The PC on which tests are run is not on the network. During the evaluation, step-by-step results are recorded in this document. Afterwards, the results of each test are recorded in the Connectathon webtool. In order to pass a test, each step within the test must be marked P. 1

3 : PDI_Basic_Viewer_General_qmts Summary This test applies to Portable Media Creators in the PDI Integration Profile that support the Basic Viewer ption. There are general requirements for the Basic Viewer in addition to the functional requirements of the application itself TF eference AD TF-1: , , , Test Setup The PDI Media with the Basic Viewer is inserted into the drive. The test computer is not on the network (ensures requirement that the network is not needed for download of software, licensing, or registration, or any other information via the Internet or local area network). For one test step, two monitors are needed. This could be the combination of a laptop screen and an external monitor. Test Action Expected esults P/F Evaluator s Comments 00 Insert PDI media into drive. The test computer is disconnected from the The Viewer works under normal user privileges (does not require admin privileges). 02 network. The Viewer automatically launches when the media is inserted (because the S on the test machine allows this, and it has not been disabled by the user). 05 The Viewer operates directly from the PDI media; it does not require software installation on the local PC. 10 The Viewer does not require install of, or permission to install, applications, frameworks (such as Java or.net versions other than 2.0), libraries (such as DLLs or ActiveX controls), device or graphics drivers, or software other than those shipped with the basic operating system. 12 When the Viewer launches, there is no disclaimer or other notice to the effect that either the images on the media or the application itself is not for diagnostic or clinical use; the 3

Adjust one to 1024x768 and the other to 1208x1024. pen the Basic Viewer. 25 With the media in the drive and the display application started, exit the display application. Browse the CD/DVD drive to find the VIEWE.BAT or Action Expected esults P/F Evaluator s Comments user is not required to agree to such conditions before proceeding to use the application. (However, the application may present a disclaimer indicating that the provider of the media has no control over the display hardware, the state of display calibration, ir other aspects of the viewing environment that may affect the suitability of the displayed images for diagnostic use). The report correctly displays without any additional preinstalled software beyond any in the S requirements (eg does not require a PDF viewer or specific fonts). The application takes advantage of the size of the primary monitor; when larger than the minimum 1024x768, then the large size is used (rather than displaying a fixed 1024x768 window). The application tolerates the presence of two monitors of different resolutions, but is not required to be able make use of both monitors. VIEWE.BAT or VIEWE.EXE exists in the root directory of the media. The user is able to manually start the Viewer using this file. VIEWE.EXE file in the root directory. 30 Start the Viewer application. Verify: The application provides immediate feedback to the user when it is invoked (eg dialog box or splash screen presented, cursor change ) If the application takes more than 5 seconds to launch, an indication of relative progress is presented to the user.

The user is able to close the Viewer by clicking on the X in the upper right corner of the viewer window. nly one instance of the Viewer is started. The user is able to successfully close the application even if the media has been removed from the drive. The Viewer may automatically terminate, or allow the user to manually close it. The media contains a VIEWE.PDF file in the root directory. The manual documents the use of the Viewer application. 5

By default, the upper leftmost viewport is selected. There is a visual indication as to which viewport is selected (eg the border is highlighted. Without manually selecting any viewports, invoke the cine tool. 05 Perform the 2 methods for selecting a viewport: - Click the Select Viewport tool and then click a viewport - Click within a viewport, then select one of the modal tools (zoom, pan, window, scroll, measurement, cross-hair) 10 Same Manually select multiple viewports by holding down the CTL key (windows) or CMMAND key (Mac) and clicking in the viewports. When the cine tool is selected, cine occurs in the upper left viewport. There is a visual indication that the viewport is selected. The user is able to manually select more than one viewport. l l

Adjust brightness/contrast in one viewport. 15 Select one of the modal tools (zoom, pan, window, scroll, measurement, cross-hair) and verify that it automatically operates on the viewport that is selected by default (ie the viewport does not need to be manually selected by the user). 20 Select one or more of the modal tools (zoom, pan, window, scroll, measurement, cross-hair) and perform that operation on images in one viewport, then in a 2 nd viewport. Window/level is adjusted in all selected viewports. Verify that the user does not need to explicitly select a viewport prior to the application of a modal tool. Verify that once a modal tool has been selected, it remains selected until the user explicitly selects another tool (eg when the measurement tool is selected, the user can make multiple measurements without having to reselect the tool). l l Test: BI_Navigation Summary This test verifies proper operation of Patient, study, and series select mechanisms Thumbnails Navigation icons 33

Using patient-select, attempt to view images from both studies at the same time (ie in different viewports). Manager, select studies, and retrieve them. These studies are from the same patient. The application allows the user to view each study in a separate viewport simultaneously Two studies with the same Patient ID but slightly different name. These studies are for two different patients. The application does not allow the user to display series from multiple patients simultaneously (ie values for both Patient Name and Patient ID must be the same in both studies) ne study; ten Select the study; then select 2 series Two series from the same study may be viewed 34

The user is able to adjust window/level for images in one series, while the display of the other series remains the same. The single series is displayed in one viewport, which uses available space within the application to display the image. Thumbnails must: - be of sufficient size to be recognizable (no less than 128x128 pixels) - be representative of the image content of the series (e.g., down-sampled from the central image of a series) - be decorated with text describing the Series Date (or if absent, Study Date), Modality and Series Description derived from the standard DICM attributes, and a count of the number of images in the series - be arranged within a scrolling strip or panel which is visible by default (though optionally a mechanism may be provided for the user to hide the thumbnail strip or panel to minimize encroachment on available screen real estate for display) - be sorted by ascending temporal order of study, and then ascending temporal or ascending Series Number within a study Note that the text decoration may overlay the 35
