Filed: 2019-12-20
Abstract: Disclosed is a limited-angle CT reconstruction method based on anisotropic total variation. According to the method, by using a low-dose and sparse-viewing-angle CT image reconstruction model to combine a fast iterative reconstruction algorithm with an anisotropic total variation method, the ubiquitous problems, in the existing limited-angle CT reconstruction method, that some areas are fuzzy, the convergence speed is low, and accurate solving cannot be achieved are effectively solved. During a solving process of a model, a ramp filter in a filtered back-projection reconstruction algorithm is introduced to pre-process an iterative equation, and alternating projection proximal is used to solve the iterative equation, and iteration is repeatedly performed until a termination condition is met. A comparison with an experiment of the existing reconstruction method indicates that the present invention can achieve a better reconstruction effect.
