Abstract
A plurality of projection images are obtained, on a basis of plural pieces of three-dimensional image data obtained by imaging an object at a plurality of different time points, by projection from a plurality of different projection directions corresponding to projection images in accordance with a three-dimensional partial region where a pixel value is increased and a three-dimensional partial region where the pixel value is decreased at a second time point with respect to a first time point among the plurality of time points, and the plurality of projection images are displayed on a display unit.
Claims15
An information processing apparatus comprising:
- an obtaining unit configured to obtain a projection image obtained by projection from a projection direction with respect to subtraction image data generated by performing subtraction processing using three-dimensional image data obtained by imaging a subject at a first time point and three-dimensional image data obtained by imaging the subject at a second time point from among a plural pieces of three-dimensional image data obtained by imaging the subject at a plurality of different time points;
- and
- a display control unit configured to display, on a display unit, the projection image obtained by the obtaining unit,
- wherein the projection image is generated using a plurality of pixel values obtained by performing maximum value projection processing on the subtraction image data and a plurality of pixel values obtained by performing minimum value projection processing on the subtraction image data.
