Abstract

Three compression algorithms were compared by using contrast-detail (CD) analysis. Two phantoms were designed to simulate computed tomography (CT) scans of the head. The first was based on CT scans of a plastic cylinder containing water. The second was formed by combining a CT scan of a head with a scan of the water phantom. The soft tissue of the brain was replaced a subimage containing water only. The results of a compression study using lossy compression algorithms is dependent on the characteristics of the image and the nature of the diagnostic task. No differences were found among the CD curves for the tested compression algorithms.
