Medicalis Corporation was established in 1999 as a joint venture between Mitra Imaging and Brigham and Women’s Hospital to design and implement a web-based system for the delivery of clinical decision support to ordering physicians. The first system, RadVise, was deployed in 2001 and served as a model for the continuous design and development of clinical decision support delivery systems. The combination of a patented decision-support knowledgebase, web-based clinical applications and a world-class integration platform make Medicalis the leading provider of diagnostic testing solutions for the electronic health record (EHR).
