Problems solved by technology

[0003] However, in the mode of taking 2 times or multiple times of averaging, the detector obtains multiple sampling points by inserting virtual integration pulses. Due to the problems of rotation speed and slip ring hole position accuracy, the integration time of the last integration pulse inserted is different from that of the previous one. There is a big difference in the integration time, which will affect the size of the data obtained after averaging by 2 or more times, and will affect the image quality and produce artifacts after data averaging

Abstract

The invention provides an interpolation calculation method, system, imaging method and computer-readable storage medium, which calculates the integration time between each slip ring hole according to the scanning speed, and then calculates each virtual integral according to the number of inserted integration pulses The length of the time can make the virtual integration time of each slip ring hole uniform, and finally make the image quality of the data sampled by the detector stable and better.

Description

technical field [0001] The present invention relates to the technical field of computerized tomography equipment scanning, in particular to an interpolation calculation method, system, imaging method and computer-readable storage medium. Background technique [0002] Computed tomography (CT scanning) technology is a technology for three-dimensional imaging of the object to be detected. In a CT scanning system, an X-ray source and a detector are arranged opposite to each other. During the scanning process, the X-ray source and detector rotate around the object to be detected and remain relatively stationary. The X-ray source radiates X-rays, and the X-rays pass through the object to be detected and are received by the detector. The signal received by the detector is processed by using 3D reconstruction technology to obtain a 3D image of the object to be detected. [0003] However, in the mode of taking 2 times or multiple times of averaging, the detector obtains multiple sa...
