CIRS 610 AAPM CT性能模体，CIRS 610模体 CIRS 610 AAPM CT性能模体，CIRS 610模体为用户提供了一个测量十个不同CT性能参数的单一测试对象。模体设计基于美国医学物理学家协会CT扫描仪Phantoms的报告＃1中提出的指南。报告＃1的目标是“（1）定义CT扫描仪的”性能“，（2）描述通过使用特定的模体进行性能测试的方法。 CT号线性插入物，高对比分辨率插入物和切片宽度插入物被容纳在8.5“直径的PMMA水箱中，其具有快速断开阀，以便于在使用之间填充和排出。 对比测试物体粘附在包括两排直径为1至0.125“的腔体的罐底部。空腔可以填充不同解决方案进行对比评估。一个铝排列的插入物被纳入坦克的盖子，并且可以互换与一个聚苯乙烯TLD插入物为剂量测量。 CIRS 610 AAPM CT性能模体，CIRS 610模体测量能力 噪声 大小独立 灵敏度可检测性 辐射剂量 机械对齐 空间均匀性 光束硬化 HU线性 切片厚度 空间分辨率和线传播功能 CIRS 610 AAPM CT性能模体，CIRS 610模体包括的材料 具有骨骼结构的组织等效躯干腔 可移动的肺，心脏，肝脏，胰腺，脾脏和肾脏 管道，耦合器，真空泵和硬件 泡沫衬里的手提箱 技术手册 CIRS 610 AAPM CT性能模体，CIRS 610模体保修信息 4年保修 CIRS 610 AAPM CT性能模体，CIRS 610模体英文介绍： The CIRS Model 610 AAPM CT Performance Phantom offers the user a single test ob[x]ject that measures ten distinct CT performance parameters. The phantom design is ba[x]sed 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 ob[x]ject 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.
