摘要： A plurality of position data are input, which indicate the position of an observation target defined in a three-dimensional space, on its three-dimensional image, which is viewed from a predetermined view point along a predetermined line-of-sight direction. A curved cross-section in the line-of-sight direction is calculated from the plurality of position data and line-of-sight data including the predetermined view point and the predetermined line-of-sight direction. A projection image is generated by projecting the three-dimensional image on the calculated curved cross-section onto a projection surface along the line-of-sight direction. The projection image is then displayed.

摘要： When medical image data is acquired by imaging equipment of modality, modality outputs an image data transfer request command to a data base, via a network. After a memory area of a TMD (temporal magnetic disc) of the data base is secured, the acquired image data is transferred from modality to the TMD. When an image data retrieval request command is input from a WS (work station) of a console to data base through network, retrieval of the image data stored in the data base is performed, the retrieved data is transferred to the WS, and is displayed. The operator requests data base to read out image data by retrieval result. Data base is searched memory address of the requested image data. When the requested image data is stored in OD (optical disc), image data stored in OD is transferred to TMD. Image data stored in TMD is transferred to WS, and is displayed.
