摘要：
Compression algorithms are widely used in medical imaging systems for efficient image storage and transmission. Lossy compression methods can achieve satisfactory compression ratios. Since image quality is a critical issue for medical diagnosis, the evaluation and quantification of information lost due to compression is required. In this study a set of compressed image quality measures, relevant to medical image quality concepts, is proposed. Measurements were carried out using ROI operations on digital test objects. As a paradigm, the assessment of the lossy JPEG algorithm available in a telematics application for healthcare is presented.
