Method and apparatus for processing medical image

A medical image processing method comprising:

• obtaining raw data in a first phase section;
• generating first motion information by using at least one partial angle reconstruction (PAR) image pair including two PAR images respectively obtained in two phase sections that face each other in the first phase section;
• generating a summed image by summing a plurality of PAR images obtained at different phases within the first phase section, and generating second motion information by updating the first motion information such that an image metric representing motion artifacts is minimized when being calculated from the summed image;
• and
• generating a reconstructed image by applying the second motion information to the raw data.

A computer program product comprising a non-transitory computer-readable recording medium having recorded thereon computer program codes which, when derived and executed by a processor, perform a medical image processing method comprising:

• obtaining raw data in a first phase section;
• generating first motion information by using at least one partial angle reconstruction (PAR) image pair including two PAR images respectively obtained in two phase sections that face each other in the first phase section;
• generating a summed image by summing a plurality of PAR images obtained at different phases within the first phase section, and generating second motion information by updating the first motion information such that an image metric representing motion artifacts is minimized when being calculated from the summed image;
• and
• generating a reconstructed image by applying the second motion information to the raw data.
