Abstract
A medical image reconstruction method includes: obtaining real projection data collected by a medical imaging device; obtaining an inverse matrix corresponding to the medical imaging device that is physically stored in advance, in which the inverse matrix is obtained by performing an inverse operation based on a system matrix corresponding to the medical imaging device, and the system matrix indicating a geometrical relationship between projection rays of the medical imaging device at each view angle and of reconstructed image pixels; and determining a reconstructed image of the real projection data according to the real projection data and the inverse matrix. By storing a large inverse matrix of the system matrix, rapid image reconstruction may be achieved through the inverse matrix and the real projection data, reconstruction efficiency of a medical image may be improved, and wide application and development of iterative reconstruction technology in clinical practice may be promoted.
