Medical imaging and diagnostic equipment (MIDE) is increasingly being networked to Picture Archiving and Communications Systems (PACS), Radiology Information Systems (RIS), Hospital Information Systems (HIS), and getting connected to the hospital intranet as well as the Internet. Failing to implement the necessary physical infrastructure can result in unexpected downtime, and safety and compliance issues, which translates into lost revenue and exposure to expensive litigations, negatively affecting the bottom line. This paper explains how to plan for physical infrastructure when deploying medical imaging and diagnostic equipment, with emphasis on power and cooling.
