JPEG2000 Compression of Thin-Section CT Images of the Lung: Effect of Compression Ratio on Image Quality

Abstract

The highest ratio that yielded visually lossless compression of thin-section CT images was 3:1. With the 5:1 ratio, there was minor image quality loss, while use of higher compression ratios (>/=7:1) caused substantial degradation of image quality and potential loss of diagnostic information.
