美国phantomlab Catphan500 CT性能测试体膜产品介绍：
产品型号：Catphan500
产品品牌：美国phantomlab
产品类别：CT性能测试体膜
产品备注：CT性能测试体膜美国phantomlab Catphan500 CT性能测试体膜产品简介：
美国Catphan 500 CT性能测试模体已得到知名CT生产公司的认同，都用它来标示CT机的成像性能。该模体较依据AAPM 1977年1号报告生产加工的注水模体有很多优点：因是固体模体，没有漏水的问题；储运箱能当模体支架，模体能探出扫描床外；低对比度分辨力模体由同一种物质不同密度材料制成等。
美国phantomlab Catphan500 CT性能测试体膜产品概述：
医疗模体：模体用来检测医院的CT性能，由塑料制成，Catphan500, Catphan600, Catphan5700, CTP500, CTP600, CTP700等. 另外一个是医院的磁共振性能检测模体，完全使用有机玻璃制成，也有两个型号，其中的圆柱形，就是Magphan® SMR170，厂家是美国模体实验室。功能：Phantomlab与物理学家兼哲学家Goodenough, Ph.D.,共同努力发展了Catphan®模体。新型的Catphan®模体设计是基于医疗成像仪器方面二十多年的科学研究和临床经验。该种模体可以应用于轴向和螺旋CT扫描成像系统的各种操作评价以及质量保证系统。不同的模块组成了Catphan®模体，这些模块尚可适用于连续20cm空间。为了在Catphan®424中使用水容器，所有Catphan®组件都是由Solid-cast材料构成。Solid-cast结构可以降低材料的吸水性和水浴模体相关的露水问题。包括Catphan®500在内共有三种基本Catphan®模体。Catphan®是为螺旋CT扫描而特殊设计的。包括Catphan®模体的选择性测试模块及其标准，经常被用于进行许多实验测量。包括以下一、参数的评估：扫描几何学(层宽和灵敏度曲线)高分辨率(ZG至20线对/厘米)体模定位验证病人定位系统验证supra-slice低对比度灵敏度subslice低对比度灵敏度空间均匀性扫描增量CT系统噪声(精度)圆对称性灵敏度(线性)象素(矩阵)尺寸动态扫描X、Y、Z轴的点扩散函数和调制传递函数(MTF)•patient alignment system check•low contrast sensitivity•comparative subslice and supra-slice low contrast sensitivity•spatial uniformity•scan incrementation•noise (precision) of CT systems•circular symmetry•sensitometry (linearity)•pixel (matrix) size•point spread function and modulation transfer function (MTF) for the x, y, and z axesCatphan® 700(Stock CTP700) – Complete Catphan® including housing and case, equipped with the following test modules:CTP682 – Geometry sensitometry and point source moduleCTP714 – 30 line pair high resolution moduleCTP515 – Subslice and supra-slice low contrastCTP721 – Wave insertCTP723 – Bead blocksCTP712 – Uniformity sectionCatphan 600®(Stock CTP600) – Complete Catphan® including housing and case, equipped with the following test modules:CTP404 – Slice width, sensitometry and pixel sizeCTP591 – Bead Geometry moduleCTP528 – 21 line pair high reslution and point sourceCTP515 – Subslice and supra-slice low contrastCTP486 – Solid image uniformity moduleCatphan® 500(Stock CTP500) – Complete Catphan including housing and case, equipped with the following test modules:CTP401 – Slice width, sensitometry and pixel sizeCTP528 – 21 line pair high resolution and point sourceCTP515 – Subslice and supra-slice low contrastCTP486 – Solid image uniformity moduleCatphan® 412(Stock CTP412) – Complete Catphan including housing and case, equipped with the following test modules:CTP401 – Slice width, sensitometry and pixel sizeCTP445 – MTF module with bead point sourceCTP446 – 20 line pair high resolutionCTP263 – Low contrastCTP486 – Solid image uniformity moduleCatphan® 424(Stock CTP424) – Complete Catphan including housing and case, equipped with the following test modules:CTP401 – Slice width, sensitometry and pixel sizeCTP445 – MTF module with bead point sourceCTP446 – 20 line pair high resolutionCTP263 – Low contrastCTP422 – Liquid bathCatphan® 440(Stock CTP440) – Complete Catphan including housing and case, equipped with the following test modules:CTP401 – Slice width, sensitometry and pixel sizeCTP592 – Low and high contrast resolution module产品编号 Description CTP700 Complete Catphan® 700 including housing, case, and test modules Includes the following: CTP682-Geometry sensitomety and point source module, CTP714-30 line pair high resolution module, CTP515- Subslice and supra-slice low contrast, CTP721 Wave insert, CTP723-Bead blocks, CTP712 Uniformity section CTP600 Complete Catphan® 600 including housing, case, and test modules Includes the following: CTP404-Slice width, sensitometry and pixel size, CTP591-Bead geometry module, CTP528-21 line pair high resolution and point source, CTP515-Subslice and supra-slice low contrast, CTP486-Solid image uniformity module CTP500 Complete Catphan® 500 including housing, case, and test modules.
