Abstract

CT (Computer Tomography) and MRI (Magnetic Resonance Imaging) provide three-dimensional data of invisible objects, which is called volume data. Volume rendering technique shows us realistic 2D images from the 3D data. In this paper, we propose a new calculation method of computer generated holograms incorporating volume rendering technique in order to create autostereoscopic images. Using the method, the fringe pattern on the hologram is calculated from the 3D data directly without intermediate process. Optical experiments were done using phantom objects and the results show that the method represents full-parallax 3D images.
