A medical image processing apparatus according to an embodiment includes processing circuitry. The processing circuitry extracts, based on a first area that is an area to which radiation is emitted and a second area that is an area affected by the radiation emitted, a cross-section that satisfies a certain condition and that passes through two points, the first area and the second area being specified by volume data and the two points being a first point included in the first area and a second point included in the second area. The processing circuitry causes a display to present an image of the cross-section.

A processing device for a radiation device is configured to carry out the steps of retrieving, from a data storage, volume data of a subject that was generated by imaging an internal structure of the subject, determining a position of an object in the subject based on the retrieved volume data of the subject, obtaining geometry information including a position of a radiation source and a position of a radiation detector, and obtaining a direction of the radiation detector, and determining a condition for imaging with the radiation source, so that the object can be captured through the imaging, based on the volume data, the position of the object, the position of the radiation source, the position of the radiation detector, and the direction of the radiation detector.

The invention provides, in some aspects, a system for implementing a rule derived basis to display volumetric image sets. In various embodiments of the invention, the selection of the images to be displayed, the generation of the 3-D volumetric image from measured 2-D images including the rendering parameters and styles, the choice of viewing directions and 2-D projection images based on the viewing directions, the layout of the projection images, and the formation of a video can be determined using a rule derived basis. In an embodiment of the present invention, the user is presented with sequential images making up a video displayed based on their preferences without having to first manually adjust parameters. The present invention allows for novel ways of viewing such images to detect microcalcifications and obstructions when reviewing Digital Breast Tomosynthesis and other volumetric mammography images.

The disclosure has an object to provide a medical-data processing device that allows generation of an MIP image suitable for diagnosis. With the medical-data processing device of the disclosure, intensity of a body surface region in three-dimensional space data is adjusted. The body surface region corresponds to a body surface of a stereoscopic image of a subject. Since the intensity of the body surface region is adjusted to be decreased, the maximum intensity is selected from a portion except for the body surface region to generate the MIP image. This prevents the body surface of the subject from appearing upon generating the MIP image. Therefore, the MIP image is obtainable having excellent visibility to the inside of the subject.
