Abstract
This paper reports on experiments concerning data reduction of digital image sequences of the heart. Since the time intensity curves (ITCs) corresponding to every picture element have a simple and regular structure, they were subjected to various one-dimensional transforms. Subsequently the ITCs were reconstructed from a number of coefficients smaller than the original number of images. The results of the different transforms are compared and discussed. It is shown that a compression factor of 10 to 15 may be achieved without loss of diagnostic information or visible image distortion.
