Using multiplex holography (MH), we tried to show a three-dimentional display of nuclear images. There were no level-down of resolution when composed to hologram. A clinical problem, existed in which some images had distortion at their edges. We examined the resolution using a SPECT phantom. In MH by planar image, both legions were 22.4 mmφ, in MH by CRT data and three-dimentional display on the CRT, both legions were 22.4 mmφ. Three-dimentional display by MH using planar image takes a long time for data collection, but there was no level-down of resolution. We used digital filters for further improvement of the quality of the original image. Band pass and Wiener filters are available, but I think it is necessary to develop the most suitable filter for each internal organ. In the results, three-dimentional display by MH is the most available method regarding education and clinical medicine.
