摘要

本章综述了传统x射线和计算机断层扫描(CT)的成像方式及其医学应用。本章介绍了x射线、x射线成像和计算机断层扫描的发现简史。讨论了用于生成正弦图的线性投影(探测器的信号与旋转角的关系)和用于图像重建的滤波反向投影。给出了直线束和扇形束X射线的计算机模拟。本章讨论了常规x射线和CT扫描成像的一些医学应用。

X-Rays and Computed Tomography Scan Imaging: Instrumentation and Medical Applications
This chapter gives a review for both conventional X-ray and computed tomography (CT) scan imaging modalities and their medical applications. The chapter presents a brief history on the discovery of X-ray, X-ray imaging, and computed tomography scan. The linear projection for the generation of the sinogram (the detector’s signals versus the rotational angle) and the filtered backprojection for image reconstruction are discussed. Computer simulations for linear and fan beams X -ray are also presented. The chapter discusses some medical applications of both the conventional X-ray and CT scan imaging.
