CIRS 610 AAPM CT性能模體，CIRS 610模體
   
CIRS 610模體為用戶(hù)提供了一個(gè)測(cè)量十個(gè)不同CT性能參數(shù)的單一測(cè)試對(duì)象。模體設(shè)計(jì)基于美國(guó)醫(yī)學(xué)物理學(xué)家協(xié)會(huì)CT掃描儀Phantoms的報(bào)告＃1中提出的指南。報(bào)告＃1的目標(biāo)是“（1）定義CT掃描儀的"性能“，（2）描述通過(guò)使用特定的模體進(jìn)行性能測(cè)試的方法。

CT號(hào)線(xiàn)性插入物，高對(duì)比分辨率插入物和切片寬度插入物被容納在8.5“直徑的PMMA水箱中，其具有快速斷開(kāi)閥，以便于在使用之間填充和排出。

CIRS 610模體英文介紹：
The CIRS Model 610 AAPM CT Performance Phantom offers the user a single test object that measures ten distinct CT performance parameters. 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 ‘performance’ of a CT scanner and (2) describe methods of performance testing through utilization of particular phantoms."

A CT number linearity insert, high contrast 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 equivalent ring that can be fit over the inserts to evaluate the effects of beam hardening.

A contrast test object 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 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’s manual, holding cradle, filling tubes and other accessories are included.
