Abstract: An information processing apparatus generates heart shape data indicating a three-dimensional shape including an internal structure of a heart of a subject based on echo image data indicating a cross-sectional image of the heart. The information processing apparatus then generates thorax shape data indicating a three-dimensional shape of a thorax of the subject based on X-ray image data indicating an X-ray image of the thorax of the subject. The information processing apparatus then decides, based on an image of the heart appearing in the X-ray image, a position and an orientation of the three-dimensional shape of the heart indicated by the heart shape data within the three-dimensional shape of the thorax indicated by the thorax shape data.

Abstract: An electronic file system includes an operating device for receiving an input for performance of an operation on an electronic file and an approval device used for approving of the operation on the electronic file. The electronic file includes an operation file on which an operation is to be performed and a restriction file indicating a restriction condition (policy) for restricting an operation performable on the operation file and a request destination for approval of the restricted operation. The operating device includes determination means for determining whether the operation to be performed on the operation file is permitted in accordance with the restriction condition described in the restriction file and means for, when it is determined that the operation corresponds to the restriction condition, transmitting to the approval device described as the request destination in the restriction file an approval request for requesting approval of the operation.
