After reviewing the components of a PACS, a set of requirements for a clinically acceptable system is outlined. The PACS concept employed by the US military is presented as an example of an integrated approach to a filmless hospital. Clinical evaluation, future applications, and current limitations of PACS technology are also reviewed.>
