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。
扫描几何学(层宽和灵敏度曲线)
·高分辨率(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
·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)
模体用来检测CT性能，由塑料制成，Catphan500, Catphan600, Catphan5700, CTP500, CTP600, CTP700等. 另外一个是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。
