PET-CT Phantom™包括内部结构(三根杆和六个球体),当用两种模式成像时,它们可以证明两个图像组的准确对准。

另外,放射性水的一个样本被水,骨骼和CT造影材料(以及仅空气)衰减,以确定基于CT的PET衰减校正工作的准确度。

PET-CT Phantom,PET CT模体用于:
PET / CT和SPECT / CT系统的验收测试
PET / CT和SPECT / CT系统的常规质量评估
评估新的图像融合软件
评估新的衰减校正算法
铝管用于注册
外部2“OD微型圆柱用于将衰减区域与非衰减区域进行比较
6“环用于对比解决方案

The PET-CT Phantom™ includes internal structures (three rods and six spheres) which, when imaged with both modalities, can demonstrate how accurately the two image sets are aligned.

In addition, a single sample of radioactive water is attenuated by water, bone and CT contrast material (as well as air only) to determine how accurately the CT-based PET attenuation correction works.

The Phantom is used for:
Acceptance testing of PET/CT and SPECT/CT systems
Routine quality evaluation of PET/CT and SPECT/CT systems
Evaluation of new image fusion software
Evaluation of new attenuation correction algorithms
Aluminum tubes are for registration
The outer 2" OD micro cylinder is for comparing attenuation region to non attenuation region
The 6" ring is for contrast solution
