概括

与双能CT (DE-CT) 相比,光子计数CT (PC-CT) 在较低的辐射剂量下提供了改进的量化 (IQ). 虽然虚拟单色成像 (VMI) 可以比较,但PC-CT在智商方面表现出色,尽管DE-CT在大型幻影中对密集材料的Hounsfield单位估计更好.

Computed Tomography

Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
