In addition to hospital image quality services, the IRIS has developed PC based software programs for quality assurance(QA) of medical imaging modalities and quantitative computed tomography(QCT) bone mineral analysis.

Automated QA

   The IRIS has developed a PC based automated QA program for CT scanners. This PC based automated QA software provides accurate measurements of the key imaging parameters recommended by the AAPM, CDRH, JMHW and HPA. In addition to providing quantitative values for each test-charts and graphs are provided to assist in evaluation of CT system performance. Data stored from these tests can be used in evaluation of long term performance of CT scanners as well as assessment of their maintenance.

   Over the last decade, several scientific papers outlining different aspects of this software have been published. These papers were presented at a number of meetings in Europe, Asia, South America, Middle East and the U.S.

   In addition to the CT software, similar programs have been developed for MRI and SPECT scanners. IRIS scientists work closely with The Phantom Laboratory(Salem, N.Y.) in the development of the Catphan^® CT Phantom, Magphan^® MRI phantom, and the Specphan^® SPECT phantom. IRIS has QA software which will operate from images of these phantoms.
