Abstract: A tomography apparatus includes a data obtainer and an image processor. The data obtainer performs a tomography scan on a moving object and obtains raw data of the object The image processor reconstructs a first tomography image of the object for a first slice section in a first phase from the raw data and reconstructs a second tomography image in a second phase, which is different from the first phase, for the first slice section of the object by using the raw data. The image processor also generates motion information indicating a three-dimensional (3D) motion of the object. The second phase is a phase beyond a phase range of the raw data.

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.
