摘要

传统的计算机断层扫描(CT)系统使用单个x射线源和安装在旋转龙门上的探测器弧线来获取一组投影数据。新型CT系统目前处于领先地位，其中一个完整的分布式x射线源和探测器环是电子打开和关闭的，没有任何机械运动，以获得一组投影用于层析重建。本文讨论了这种新的CT结构所带来的新的传感和重建范式。

Signal Sensing and Reconstruction Paradigms for a Novel Multi-Source Static Computed Tomography System

Conventional Computed Tomography (CT) systems use a single X-ray source and an arc of detectors mounted on a rotating gantry to acquire a set of projection data. Novel CT systems are now being pioneered in which a complete ring of distributed X-ray sources and detectors are electronically turned on and off, without any mechanical motion, to acquire a set of projections for tomographic reconstruction. This paper discusses new sensing and reconstruction paradigms enabled by this new CT architecture.
