Instructions

To run this test, follow these steps:

1. Obtain the RSNA 2005 PDI Demonstration CD. If you do not have a physical copy of the CD, download the ISO image of the CD from the MESA distribution page and create a CD from the ISO image.

2. Use your DICOM application to open the DICOMDIR file on the RSNA CD.

3. Select and display all of the studies on the CD. For those studies with multiple images, you can select a small subset of the images.

4. Create a simple text file that lists each vendor that submitted data and a simple yes/no that indicates whether you could display the data. If you had problems displaying the data, submit further evidence or documentation (to Kudu/Gazelle). Also, send an email to the Project Manager so he/she can investigate.

Evaluation

1. Submit the text file as the results for this test.

Mammography Acquisition Workflow Integration Profile Tests

This section describes tests that are specific to the IHE Mammography Acquisition Workflow Integration (MAWF) profile.

Image Display Test 4100: MAWF Vendor Interoperability - Recall Case

This test Image Display and Image Managers access to sample images for the recall case created by MAWF Acquisition Modalities prior to the Connectathon.

References

RAD TF-2:4.16.4.2.2.5

RAD TF-2:4.5.4.2.2.2

RAD TF-2:4.8.4.1.2

Instructions

Modalities will create both FOR PRESENTATION and FOR PROCESSING images for a mammography study. Then they will simulate a "Recall" case and encode "Recall for patient symptoms/clinical findings" as the Reason for Requested Procedure. Modalities are asked to submit samples into Gazelle 3 weeks prior to the MESA test deadline or earlier. The goal is to avoid surprises on the Connectathon floor.

Image Display and Image Manager systems will then find these samples in Gazelle under Connectathon -> List of Samples. Select your system name and look under Samples available for rendering to find the sample images for test 4100. Your task is to test with these samples prior to the Connectathon. Do not complete this test before those samples are available. See expected behavior for Image Displays in the TF references above.

Create a short txt file indicating you have shared or accessed these samples. If you find a problem, contact the Project Manager.

Upload that txt file into the Gazelle system as results for this test.

Image Display Test 4102: MAWF Vendor Interoperability - View Correction

Image Managers in the MAWF profile are required to support DICOM KOS objects as well as mammography images.

This test gives Image Managers and Image Displays access to sample images and KOS objects created by MAWF Acquisition Modalities and Evidence Creators prior to the Connectathon. They are asked to submit samples into gazelle 3 weeks prior to the MESA test deadline or earlier. The goal is to avoid surprises on the Connectathon floor.

References

Upload that txt file into the gazelle system as results for this test.

BIR - Basic Image Review

This section describes tests that are specific to the Radiology Basic Image Review Profile

Test Case 4700: BIR Connectathon tests

The Image Display actor in BIR is unlike other IHE actors in that its requirements are primarily functional and do not require exchange of messages with other actors. At the Connectathon, a monitor will sit down at your system and run through a set of tests to evaluate the requirements in the BIR profile. With this test, we are providing you with the test steps and the accompanying images in advance of the Connectathon. We expect you to run these tests in your lab in preparation for the Connectathon itself.

Instructions

1. Download the Connectathon Test Plan for BIR Image Display actors in Google Drive under IHE Documents > bir_data_sets > data_sets > BIR_Image_Display_Connectathon_Tests-2014-04-07.pdf: https://drive.google.com/drive/folders/1nOEF5HnztNfiNBGM36ZjqCbcJZUXc92o

2. Download the BIR test images (BIRTestData_2015.tar.bz2) found at https://drive.google.com/drive/folders/1nOEF5HnztNfiNBGM36ZjqCbcJZUXc92o

3. In that directory, you will also find an index to the BIR dataset. See Google Drive under IHE Documents > bir_data_sets > data_sets >_README_BIR_dataset_reference_2014-04-07.xls: https://drive.google.com/drive/folders/1nOEF5HnztNfiNBGM36ZjqCbcJZUXc92o

4. Run the tests using your Image Display application. On or before the MESA test deadline, create a text file that briefly describes your progress in running these tests. Upload that file into gazelle as the result file for test 4700.

Evaluation

There is no pass/fail for this. We want to make sure you're making progress toward what is expected at the connectathon.

IID - Invoke Image Display profile tests

The tests in this section apply to Image Display actors in the Radiology domain Invoke Image Display profile.

Test Case 5100: IID - Prepare Connectathon Test Data

To enable Connectathon testing, the Image Display is required host studies on its Image Display.

There is one Connectathon test -- IID Invoke Display -- to exercise the Image Display and Image Display Invoker in the IID profile. The 'Special Instructions' for that test ask you to host a set of studies. This pre-Connectathon 'test' ensures you have the proper data loaded on your system prior to arriving at the Connectathon.

We do not provide specific studies for you, but rather define the characteristics of the studies you should bring

Instructions

1. Come to the Connectathon with:

• at least 3 studies for the same patient, ie will have the same value in patient ID, but the accession number and study dates will be different for each of these studies.
• at least one other study for a different patient
• a study containing a KOS object identify at least one image in the study as a 'key image'

Evaluation

1. Create a text file that indicates that you have completed the preparation described above. Upload that text file into Gazelle Test Management for this pre-Connectathon test case.

MESA Image Set

The tests in this section apply to general Image Display and Image Manager actors in the Radiology domain for profiles such as Scheduled Workflow.

Sample Images - MESA Test Data

The MESA Tools are now retired. They were distributed and supported by Steve Moore of Washington University in St. Louis. Those tools contained a set of images that would be generally useful for Image Display and Image Manager actors to test with in their home lab.

This test gives you access to those images.

Instructions

1. The MESA Image Set is now in a zip file in Google Drive under IHE Documents > Connectathon > test_data > RAD-profiles > MESA_tools_image_set: https://drive.google.com/drive/folders/1Ys0zmqb8iMT2fXSfPorUCeP2trjakO77

2. There are no specific tests defined. You are free to use these images in a way that is beneficial to you.

Evaluation

1. There are no results to submit into Gazelle.
