Abstract:
1. A medical imaging apparatus comprising: an imaging part configured to capture a cyclically moving subject in order to acquire a plurality of medical image data representing said subject over a single cycle or more; a ROI setting part configured to set a first region of interest of a tissue represented in medical image data acquired in a first time phase included in a one-cycle interval and to set a second region of interest of said tissue represented in medical image data acquired in a second time phase differing from said first time phase included in said one-cycle interval; a tracking part configured to track in each time phase a position corresponding to said first region of interest in said one-cycle interval including remaining time phases based on medical image data acquired in each time phase included in said one-cycle interval, and configured to track in each time phase a position corresponding to said second region of interest in said one-cycle interval including the remaining time phases based on the medical image data acquired in said each time phase; a position correction part configured to obtain position information of a region of interest of said tissue in said each time phase that passes through both the position of said first region of interest set in said first time phase and the position of said second region of interest set in said second time phase, based on position information of said first region of interest and said second region of interest in each time phase acquired by said tracking part; a motion-information calculator configured to obtain motion information of said tissue based on said position information of the region of interest in said each time phase obtained by said position correcting part; and a display controller configured to cause a display to display said motion information, wherein said position correction part is configured to obtain position information of the region of interest of said tissue in each time phase by smoothly connecting the position of said first region of interest and the position of said second region of interest in a time phase between said first time phase and said second time phase.
