Rearrangement method, CT scanning device and readable storage medium

The invention provides a rearrangement method, a CT scanning device and a readable storage medium. The rearrangement method comprises the following steps: transposing basic data formed by a plurality of pieces of fan-shaped beam projection data, and calculating and outputting parallel beam projection data based on the transposed basic data. According to the configuration, the internal structure of the basic data is changed through data transposition, so that data related to the same parallel beam projection data exists in the same row of the basic data, the number of access times to the first storage medium when one parallel beam projection data is generated is reduced, the rearrangement time is shortened, and the rearrangement efficiency is improved. The problems that in the prior art, memory access of a CT rearrangement algorithm is frequent, the speed is too low, and the reconstruction speed of the whole image reconstruction algorithm is affected are solved. 本发明提供了一种重排方法、CT扫描装置及可读存储介质。其中，所述重排方法包括：将多个扇形束投影数
