PURPOSE:To obtain a clear blood flow image even in image data for which an inter-polation processing is performed by comparing picture element values of voxel data which becomes an object and voxel data scattered in its vicinity, and setting the maximum picture element value as a new picture element value of the voxel data which becomes the object. CONSTITUTION:When the voxel which becomes a processing object is an object voxel 7, each adjacent voxels 10-10 prevent on its periphery becomes an object of comparison. In such a state, as a result of comparison of the object voxel 7, and the image value of each adjacent voxels 10-10, that which becomes the maximum picture element value is written in a free voxel 9 as a new voxel 11. Subsequently, this processing is performed with regard to each voxel of box-cell data 6, and by writing new data in each voxel of the free voxel 9, processed voxel data is generated. That is, in the processing executed therein, in the case one piece of voxel having a large signal value is present thereon, the signal value of several voxels prevent on its periphery also becomes the same size as the value. |
