Abstract: The present invention discloses a method for making an easy-to-view computed tomography (CT) sheet. The method is implemented by the following modules, including an X-ray tomographic scanning device, a computer system, an operating system, and a printing system. The X-ray tomographic scanning device is composed of an X-ray generator, an X-ray tube, and an X-ray detector. The X-ray generator of the X-ray tomographic scanning device is used for X-ray generation. Through increasing detection accuracy of the detector inside the scanning device, radiation dose can be effectively reduced, thereby avoiding large radiation hazards to a patient during scanning. In this way, image quality is improved without increasing the radiation dose or even when the radiation dose is reduced. In addition, a processing method for image reconstruction is further improved under joint action of multiple groups of X-rays, thereby further improving data generation.

Abstract: The present invention discloses a computed tomography (CT) system and a CT image reconstruction method. The method is implemented by an information processing system module, a display terminal module, an image reconstruction system module and a CT system module. The information processing system module is composed of an information receiving system module, an information sending system module and an information processing system module. During scanning, different nodes are arranged and quickly scanned to obtain data of a node, and then data of different nodes is synchronized, collected and summarized, so that a reconstruction unit can be analyzed, an objective function can be optimized, and data can be quickly analyzed and processed. In this way, the CT system and the CT image reconstruction method resolve the problems that an existing CT system and CT image reconstruction method have high requirements for projection data sets, and scanning requires a long time.
