Sequential approximate image reconstruction method, sequential approximate image reconstruction program and tomographic apparatus

摘要

PROBLEM TO BE SOLVED: To provide a successive approximation image reconstruction method, successive approximation image reconstruction program, and tomography apparatus that in reconstructing an image using a successive approximation method, are capable of efficiently executing reconstruction by shortening a calculation time even in the case of resuming reconstruction of the image.SOLUTION: This successive approximation image reconstruction method adopts a configuration in which when an image after first image reconstruction processing having the number of repetition of 100 is obtained and the image after reconstruction has insufficient image quality, image reconstruction is resumed after reading a reconstruction image and state variable at the time of completing the reconstruction having the number of repetition of 100.SELECTED DRAWING: Figure 4
