A method and apparatus for processing three-dimensional video signals representing a solid subject comprises, radiating the subject, receiving radiation from the subject with receptors on three axes intersecting the subject to produce three planar images of the subject volume normal to the three respective radiation axes. The picture elements of the three planar images are converted into three corresponding sets of planar video pixel signals which are converted into voxels and written at the three radiation axes into superimposition in a three dimensional storage matrix such that coincidence of three pixels in the three respective images stores a single voxel representative of the superposition of the three pixels. The voxels in the matrix can then be addressed by a view selector at an angle other than the three original radiation axes to read the selected two dimensional view out of the matrix to a display or recorder.
