MeetsguidelinesinAAPMReport#1“PerformanceEvaluationandQualityAssuranceofCTScanners”

The CIRS Model 610 AAPM CT Performance Pha*m offers the user a single test object that measures ten distinct CT performance parameters. The pha*m design is based on the guidelines presented in Report #1 of the American Association of Physicists in Medicine Task Force on CT Scanner Pha*ms.  The goals of report #1 were to “(1) define ‘performance’ of a CT scanner and (2) describe methods of performance testing through utilization of particular pha*ms.”

A CT number linearity insert, high co*ast resolution insert and slice width insert are housed in an 8.5 “ diameter PMMA water tank with quick disconnect valves for ease of filling and draining between use.  Also included is a 0.25” bone equivale*ing that can be fit over the inserts to evaluate the effects of beam hardening.

A co*ast test object is adhered to the bottom of the tank that includes two rows of c*ities from 1 to 0.125” diameter.  The c*ities can be filled with various soluti* for co*ast evaluation.   An aluminum alignment insert is incorporated in the lid of the tank and can be interchanged with a polystyrene TLD insert for dose measurements. A user’*anual, holding cradle, filling tubes and other accessories are included.
