Abstract

Novel photon-counting detector CT (PCD-CT) has the potential to address the limitations of previous CT systems, such as insufficient spatial resolution, limited accuracy in detecting small low-contrast structures, or missing routine availability of spectral information. In this review article, we explain the basic principles and potential clinical benefits of PCD-CT, with a focus on recent literature that has grown rapidly since the commercial introduction of a clinically approved PCD-CT.

摘要

新型光子计数探测器 CT（PCD-CT）有可能解决先前 CT 系统的局限性，例如空间分辨率不足、探测小的低对比度结构的准确性有限，或者常规缺乏光谱信息。在这篇综述文章中，我们解释了 PCD-CT 的基本原理和潜在的临床益处，重点介绍了自临床批准的 PCD-CT 推出以来，文献数量迅速增加的最新研究。
