Each new PACS offers an extension of the existing possibilities by adding various “new” or “useful” functions or by changing the operating characteristics of the system (transfer speed, processing speed, the size of processed images, the volume of the archive, etc.). Despite this growing up, some of the main disadvantages of this class of systems persist: the systems are complex and expensive to acquire, replace, maintain, or repair.
