The invention relates to an algebraic reconstruction method of an improved weight coefficient matrix and belongs to the CT projection data reconstruction method technology field. The method mainly aims at solving problems of logical loopholes in a Ray-Box Intersection weight coefficient matrix algorithm and a fuzzy SART+TVM reconstruction image detail based on a bilinear interpolation. Through improving the Ray-Box Intersection weight coefficient matrix algorithm, reconstruction time is shortened, the image detail is maintained and a signal to noise ratio is increased. Simultaneously, a TVM algorithm is used as a bound term, an iteration reconstruction convergence speed is accelerated, artifacts and noises of the reconstruction image are reduced and reconstruction image quality is effectively increased.
