PREFACE The Picture Archive and Communication System (PACS) introduced in the early 1990s, was a computer system designed to provide aid in diagnostic image reading and data management, in the world of conventional X-ray films. Initially, these systems were handling monochrome images generated from Ultrasound, CT and MRI. As the technology of diagnostic devices and IT advanced, the use of color images has become more prominent. This advance in technology is driving increased demand for PACS monitors capable of diagnostic color image reading. Commercially available color LCDs are not adequate for diagnostic reading of grayscale images because both the brightness and the contrast levels are too low compared to monochrome displays. Therefore, a mix of color and monochrome LCDs is a common configuration for todays PACS to support reading different applications. It is evident that there is str
