Abstract

An information processing apparatus according to the present invention is configured to project a given region (e.g., region of interest or lesion of interest) in a three-dimensional image (e.g., MRI image or X-ray CT image) onto a plane including a two-dimensional image (e.g., ultrasonic image) of an object, and cause a display unit to display an error range caused by projection (range where a corresponding region of the region of interest in the two-dimensional image may exist, also referred to as a search range) including the projected region in such a manner that the error range is overlaid on top of the two-dimensional image. Therefore, a user is able to efficiently search for the corresponding region in the two-dimensional image which corresponds to the region of interest in the three-dimensional image.

Claims8

Dependent claims

An information processing apparatus comprising:

a three-dimensional region acquisition unit configured to acquire first positional information on a three-dimensional region of an object;
a tomographic image acquisition unit configured to acquire second positional information on a tomographic image of the object;
and
a display control unit configured to cause a display unit to display, with the tomographic image, information on a cross-section of the three-dimensional region, the information on the cross-section representing an intersection of the three-dimensional region and a plane of the tomographic image,
wherein the display control unit is configured to determine a display style of the information on the cross-section on the basis of information on a positional relation, obtained by using the first and second positional information, between the cross-section and the three-dimensional region, and
wherein the display control unit is configured to cause the display unit to display, with the tomographic image, the information on the cross-section in the display style.
