Abstract :
Unlike conventional radiographs, the detail contained within Nuclear Medicine images is not fine in its structure. Consequently, it is possible that some loss of detail may be tolerable when using data compression techniques in image telecommunication. This study has been performed to compare a software implementation of the linear predictive coding method with a hardware based 2 dimensional cosine transform (2DCT). Using 50 normal bone scans with induced defects of varying significance, an experienced observer viewed the data in random order and receiver operating characteristic curves (ROC) were constructed to compare the responses.
