Abstract

The complexity of modern Picture Archiving and Communication Systems (PACS) confronts the potential user with a bewildering array of specifications, of which those effecting image quality are of primary importance. This paper reviews some of the basic concepts of PACS image acquisition and display and the relationship of the specifications for each to image quality. The key parameters of images quality for image digitization devices are spatial resolution, dynamic range, pixel accuracy and signal to noise ratio. On the output side critical factors are brightness, spatial and contrast resolution, stability, and uniformity. The concept of frame buffer depth vs. display depth for CRT monitors is reviewed, and the correspondence of CRT images to film based images is discussed. The principles of sampling theory and the Nyquist limit are also discussed. Through an understanding of the concepts presented in this paper, the PACS user (or potential user) will be in a better position to evaluate PACS for his/her clinical application.
