摘要
光子计数计算机断层扫描（PCCT）是一种新型计算机断层扫描检测技术，它使用光子计数探测器将单个 X 射线光子直接转换为电信号，有望克服以往 CT 系统的局限性，如空间分辨率有限或缺乏光谱信息等。PCCT 技术的发展有望提高图像分辨率、对比度和诊断准确性，同时减少对患者的辐射剂量。在这篇综述文章中，我们旨在评估 PCCT 的基本原理和潜在临床优势，尤其关注不断发展的最新文献，以及这种方法将为心血管和神经放射诊断成像领域带来的细致变化。
The revolution of photon-counting CT towards new horizons of diagnostic imaging
Photon-counting Computed Tomography (PCCT) is a new computed tomography detection technology that uses photon-counting detectors to convert individual X-ray photons directly into an electrical signal and has the potential to overcome limitations of previous CT systems, such as limited spatial resolution, or lack of spectral information. The upcoming development in PCCT technology promises to enhance image resolution, contrast, and diagnostic accuracy while reducing radiation doses to patients. In this review article, we aim to evaluate the basic principles and potential clinical benefits of PCCT, with particular attention to the constantly evolving recent literature and the changes that this method will meticulously bring to the world of cardiovascular and neuroradiological diagnostic imaging.
