title = "Fast Registration Algorithm of MVCT and KVCT Based on Mutual Information",
abstract = "Mutual information-based image registration is a common method for placement registration in radiotherapy. This paper uses the ART (Algebraic Reconstruction Technology) algorithm to reconstruct the electronic portal imaging device (EPID) field images obtained during low-dose radiotherapy. The reconstructed results MVCT and planned KVCT are used for maximum mutual information registration. The mutual information registration algorithm proposed in this paper combines gray level compression and area search, which greatly improves the speed of maximum mutual information registration. The feasibility of the algorithm is verified by experiments, which are divided into eight groups of different phantom placement and one group of phantom deformation to explore the low-dose rigid registration ability and the ability to resist cross-period lesion changes of the algorithm.",
