A process and system for constructing three dimensional images by acquiring two dimensional image data maps of two spaced apart planes and using binary interpolation to provide image data on planes between the two spaced apart planes. The acquired image data is first converted to "bit" data maps denoting whether an organ of interest, for example, occupies the elements of the spaced apart planes. The bit maps are used to obtain distance maps denoting where there is transition of values in each element of the bit maps. The distance maps and at least one of the bit maps are used to obtain bit values of interpolated planes between the spaced apart acquired planes for use in constructing three dimensional images.
