Abstract
A computer program for manipulating diagnostic images obtained with computed tomography or magnetic resonance systems spatially compresses acquired non-isotropic data to isotropic coordinates as stored in computer memory. A view axis along which a projected image is to be displayed is adjusted to reflect this distortion. After projecting the voxel data to pixels of an image, the data is decompressed to remove any distortion. The decompression operates over the limited number of pixels rather than the entire set of voxels providing faster image generation.
