3 Overview

CT imaging for medical testing and evaluation of the physical parameters of the die body (hereinafter referred to as CT phantom) generally consists of water on module empty Resolution between modules, module density resolution, slice thickness and CT value linear modules and other components (or components) components. respectively CT imaging for the detection of water in CT values and their uniformity and noise, spatial resolution, density resolution, slice thickness, The accuracy of CT values and other indicators. Now see there are two categories, based on water as a homogeneous medium performance phantom (water phantom), the other is Water equivalent of organic material is a homogeneous medium performance phantom (water equivalent solid mold).
