From: Development of an algorithm to automatically compress a CT image to visually lossless threshold
Study design. *Independent variables include five image features (image standard deviation, image entropy, relative percentage of low frequency energy, variation in high frequency, and visual complexity) and DICOM header information (effective mAs, field of view, section thickness, and reconstruction filter). DICOM: digital imaging and communications in medicine; VLT: visually lossless threshold
