Photon-counting detector (PCD) is a novel computed tomography detector technology (photon-counting computed tomography-PCCT) that presents many advantages in the neurovascular field, such as increased spatial resolution, reduced radiation exposure, and optimization of the use of contrast agents and material decomposition. In this overview of the existing literature on PCCT, we describe the physical principles, the advantages and the disadvantages of conventional energy integrating detectors and PCDs, and finally, we discuss the applications of the PCD, focusing specifically on its implementation in the neurovascular field.
光子计数探测器（PCD）是一种新型的计算机断层扫描探测器技术（光子计数计算机断层扫描-PCCT），在神经血管领域具有诸多优势，例如提高空间分辨率、减少辐射暴露以及优化造影剂的使用和物质分解。在这篇关于PCCT现有文献的综述中，我们描述了物理原理、传统能量积分探测器和PCD的优缺点，最后，我们讨论了PCD的应用，特别关注其在神经血管领域的应用。
