摘要： A virtual plane of projection on which a virtual three-dimensional object constructed by a set of specific structures oriented in predetermined directions is projected is set. First, while generating a basic image by projecting one specific structure oriented in a predetermined direction onto the virtual plane of projection, a reference image position corresponding to a reference position of the one specific structure in the basic image is recognized. At the time of projecting a virtual three-dimensional object onto the virtual plane of projection, each of reference projection positions in which the reference positions of specific structures constructing the virtual three-dimensional object are projected is detected. Further, by combining adjusted basic images generated by adjusting the positions of the basic images relative to the virtual plane of projection in accordance with the reference projection positions, a display image is generated.

摘要： The present invention proposes a technique capable of accurately grasping position and angle of a radiation generator at the time of image capturing. At the time of obtaining a plurality of transmission images by detecting radiation emitted from a emitting generator and passing through a specimen via a predetermined member (for example, a diaphragm) by a detector for a plurality of times while changing a relative position relation and a relative angle relation of the emitting generator to the detector, an outer-edge shape of a radiation area irradiated with the radiation on a detection surface of the detector from the emitting generator is recognized. On the basis of the outer-edge shape of the radiation area and an inner-edge shape of a predetermined member, the relative position relation and the relative angle relation of the emitting generator to the detector are obtained.

摘要： When volume data of a three-dimensional object to be processed is read and stored into a predetermined storage, first, a plurality of reference planes are set and a plurality of reference distance maps each indicative of distribution of distances between the three-dimensional object and each of the reference planes are generated.

摘要： An object of the present invention is to provide the technology capable of appropriately balancing the preciseness of contour extraction and calculation cost. In order to achieve this object, an energy function setting section sets an energy function that is expressed by a weighted linear sum of a plurality of kinds of energy terms defined correspondingly to a state of an active curve and is formulated so as to have a smaller value as approaching a shape of the contour to be extracted, and an iterative computation processing section minimizes the energy function by an iterative computation. An end instruction section sets an auxiliary function formulated so as to monotonously increase in accordance with the number of iteration times of iterative computation and sets a judging function expressed by a linear sum of the auxiliary function and the energy function. Then, a point of time when a local minimum appears in the judging function in the course of the iterative computation is judged as the end timing of iterative computing.

摘要： The present invention provides a technique capable of making a user easily grasp a relative position of an ROI in image display by volume rendering and capable of displaying an image promptly. Upon generating an image for display on the basis of volume data by volume rendering, a region of interest (ROI) in a three-dimensional region corresponding to volume data is designated. A first display image portion of the ROI is generated by a normal computing method of a relatively large computation amount. On the other hand, a second display image portion of the region other than the ROI is generated by a simplified computing method of a relatively small computation amount.
