Abstract: A medical image registration method and apparatus are described. By performance of a medical image registration method, a highly accurate registered image, in which breathing deformation information is considered, may be obtained by generation of non-real-time medical images in which the breathing deformation information is reflected before a medical procedure is conducted and by rigid registration of a real-time medical image and the generated non-real-time medical images during the medical procedure.

Abstract: Provided is a medical image processing apparatus including a processor. The processor obtains raw data in a first phase section and generates first motion information by using at least one partial angle reconstruction (PAR) image pair including two PAR images respectively obtained in two phase sections in the first phase section that face each other. The processor also generates a summed image by summing a plurality of PAR images obtained at different phases within the first phase section by using the first motion information Second motion information is generated by updating the first motion information such that an image metric representing motion artifacts is minimized when being calculated from the summed image and a reconstructed image is generated by applying the second motion information to the raw data.
