PRO MEDICUS LIMITED (PME) is a software company providing technical solutions for radiologists across Australia, the United States and to a lesser extent, Europe. The company's earlier years as a listed entity were focussed on radiology information systems, or RIS products. These can be thought of as a management tool for radiology providers, much like a practice management system for accountants. Whilst Pro Medicus retains a strong foothold in this market, particularly here in Australia, the acquisition of Visage Imaging in 2009 has seen the company evolve in to a leading provider of Picture Archive Communication Systems (PACS) products on a global scale.
