Abstract
Providing the clinician with an accurate visual representation of digital nuclear medicine data requires 1) interpolation to fill in the intensity field between grid points, 2) correction for grayscale nonlinearities inherent in the display and film, and 3) sufficiently fine graylevel resolution to avoid generating artificial contours. Results from preliminary experiments using a precision computer display/film system have been encouraging, indicating improved image interpretation is frequently possible compared with both conventional analog scintigrams and commonly available computer displays, A wider range of count rate data was visible in the digital images giving better identification of low count rate areas, display artifacts due to regularly spaced data samples were eliminated as were contour artifacts caused by too few graylevels, and the relevant anatomy and or pathology was frequently demonstrated with greater clarity. Clinical examples will be presented which illustrate the benefits to be gained by using these techniques.
