Abstract
A medical apparatus includes an acquirer, an associator, and a display controller. The acquirer acquires information indicating a respiratory waveform of an object and acquires fluoroscopic images of the object captured in time series. The associator associates a tracking value which fluctuates according to a respiratory phase of the object, based on the time-series fluoroscopic images. The display controller causes a display to display the respiratory waveform and a waveform of the tracking value in a comparable form.
