摘要： According to one embodiment, a three-dimensional image processing apparatus includes at least a storage, an inputting unit, an image generating unit and a pointer controlling unit. The storage stores volume data of a target. The inputting unit receives an input operation for moving a pointer. The image generating unit generates a superimposed image in which a rendering image generated by performing a rendering process on the volume data and a pointer image are superimposed in consideration of information of depth. The pointer controlling unit obtains information of a three-dimensional position of the pointer. When the pointer is on the rendering image, the pointer controlling unit moves the pointer along a three-dimensional surface of a target contained in the volume data.

摘要： Positioning images are created by a projection-image creating unit before imaging, and the positioning images are grouped and stored by a projection-image storage unit for each preset. When imaging is started, a positioning-information calculating unit calculates positioning parameters using the positioning images stored in the projection-image storage unit. An analysis-image-for-synthesis creating unit creates an analysis image using the positioning parameters, and an analysis-image synthesizing and displaying unit synthesizes the analysis image with a live image and displays a synthesized image. When an imaging direction of an X-ray angiography apparatus is changed, a positioning-information updating unit directly updates the positioning parameters based on an amount of change of the imaging direction.
