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。空腔可以填充各种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.
