Testing Overview: CT (Revised 1-27-2020)
Modified on: Mon, 27 Jan, 2020 at 10:05 AM
There are three portions to your ACR CT Accreditation submission:
Annual System Performance Evaluation Summary
To achieve ACR CT accreditation, a CT unit must pass both the clinical and phantom image quality tests.
You must utilize the services of a qualified medical physicist (QMP) for the Annual System Performance Evaluation, oversight of your facility’s technologist quality control (QC) program and the dosimetry portion of your phantom testing.
The QMP for all sites applying for accreditation, initial or renewal, must demonstrate compliance with the ACR requirements for quality control and Annual System Performance Evaluation or Acceptance Testing Evaluation (for new units or following major repairs) as outlined in the CT Quality Control Manual. The ACR strongly recommends using the services of a qualified medical physicist for the image quality control portion of your phantom submission.
After your new or renewal application is processed, an online testing packet will be activated which will contain all clinical and phantom data forms required for accreditation review. Your facility will receive an email with a link to the online testing packet as well as a link to the electronic PDF version of the CT Quality Control Manual. Your facility user must log into the account and fill out all forms required in the online Testing Package. The testing packet must be submitted online.
The online testing packet has the image submission due date, 45 calendar days from the online testing packet link was emailed to the facility. You must collect your test images and return them to the ACR by that date. Failure to meet this due date will jeopardize completion of your accreditation. Thus, if your facility is renewing its accreditation, we cannot guarantee completion in a timely fashion before your ACR accreditation certificate expires. If your site cannot submit the required materials by your testing package due date, contact the ACR immediately.
Prior to submission, your supervising physician should ensure that all of your facility’s protocols meet the minimum requirements listed in the Clinical Image Quality Guides.
When selecting images for submission, you must be aware of the following:
Your supervising physician should review all materials submitted for accreditation.
Choose examples of your best work.
Submit localizer or scout sequences with all examinations with cross-reference locations.
The submission of examinations performed on models or volunteers is strictly prohibited and may jeopardize accreditation.
Images submitted for each individual examination must be from the same patient (i.e. all brain images must be from the same brain examination).
All clinical and phantom examinations submitted must have been performed within 6 months of the date on the testing package that was released to the facility. No images will be accepted for review that predate this date by more than six months.
Up to four specified phantom scans and corresponding dosimetric data may be required depending on the facility’s use of the unit and the clinical modules and patient type chosen in the accreditation application for each unit.
