Abstract

The gray level dynamic range of clinical MR transaxial head images from four manufacturers were studied by examination of image bit planes for the presence of spatial information or noise. Both calculated and measured voxel signal-to-noise ratios were determined. Also, the power spectrum of image bit planes were produced to demonstrate that the noise of lower bit planes is spectrally white and contain no information. These observations point to a six and at most seven bit gray level dynamic range for the images studied.
