ACR Gamma Camera Testing & ACR Certification

The American College of Radiology (ACR™) Certification is an important requirement at many nuclear imaging locations.

       Attaining ACR Certification can be a time consuming and frustrating process for many new nuclear imaging facilities.  This process requires attention to detail and special camera imaging procedures. Ohio Valley Imaging Solutions can remove the burden of your ACR Accreditation with our ACR Certification Testing Service designed to streamline ACR accreditation.

Not only does OVIS have the clinical experience to evaluate image quality required for ACR Certification, OVIS also has the equipment expertise to resolve imaging issues that may delay ACR Certification.  Having both equipment and clinical skill sets in one organization can speed your certification process and reduce your cost.

ACR CAMERA TESTING

The purpose of ACR Gamma Camera Testing & Certification is to verify a new or moved gamma camera meets NEMA, manufacturer and/or class specifications. Acceptance tests are the most thorough and, therefore, the most costly tests necessary on gamma cameras. The American College of Radiology (ACR™) and some states require acceptance tests on all new gamma camera installations and cameras that have been moved. According to the ACR™’s Nuclear Medicine and PET Requirements, “Acceptance tests must be performed on systems when they are installed.”

NUCLEAR GAMMA CAMERA ACCEPTANCE TESTING

Acceptance Testing is widely recommended or required by various governmental and professional organizations including NRC, JCAHO, ACNP, ACR, ICANL and SNM. These tests are to be performed before a camera is first used for clinical imaging. Acceptance Testing is used to assess whether a camera is safe and performing adequately for clinical use, to determine if the camera is performing in accordance with the manufacturer’s specifications and to verify the camera was installed correctly. Acceptance Testing does not eliminate the need for Routine Quality Control and conversely, Routine Quality Control does not eliminate the need for Acceptance Testing. Rather, Acceptance Testing assesses an additional set of camera parameters as well as provides a baseline or benchmark performance level that is continuously monitored by the Routine Quality Control Procedures. A camera may pass tests designed to evaluate planar performance but not pass the more stringent requirements for Tomographic usage.
