Abstract

PURPOSE:To obtain a pseudo three-dimensional reprojected picture with the use of a two-dimensional picture processing means by adding continuous tomographic images while dislocating them according to a reprojecting direction, spatially filtering them, matching a scale for the obtained picture, and obtaining the reprojected picture. CONSTITUTION:The continuous tomographic images obtained from a tomographic image preparing device 1 are stored by a two-dimensional picture storing means 2 and then, the picture element values of the respective tomographic images are added while the respective tomographic images are dislocated according to the reprojecting direction (visual direction) by a two-dimensional picture adding means 3. Thereafter, the picture added by the two-dimensional picture adding means 3 is performed the interpolating processing by a two-dimensional spatial filtering means 4, and then, the scale is matched by a two-dimensional affine transformation means 5, and the three-dimensional reprojected picture is obtained. Thus, the pseudo three-dimensional reprojected picture is obtained while the prompt and simple interpolating processing is performed by using the two dimensional picture processing means.
