CIRS 610 AAPM CT性能模體，CIRS 610模體英文介紹： The CIRS Model 610 AAPM CT Perbance Phantom offers the user a single test b that measures ten distinct CT perbance beters. The phantom design is based on the guidelines presented in Report #1 of the American Association of Physicists in Medicine Task Force on CT Scanner Phantoms. The goals of report #1 were to “(1) define ‘perbance’ of a CT scanner and (2) describe bs of perbance testing through utilization of particular phantoms.”
A CT number linearity insert, high contrast resolution insert and slice b 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 equivalent ring that can be fit over the inserts to buate the effects of beam hardening.
A contrast test b is adhered to the bottom of the tank that includes two rows of cavities from 1 to 0.125” diameter. The cavities can be filled with various solutions for contrast buation. 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’s manual, holding cradle, filling tubes and other accessories are included.
