case study

Greenway Health

Greenway Health’s Medical Manager product was one of the first practice management systems to go online. At the time, however, insurance claims were still paper-based. Anticipating the shift to electronic information management, Greenway wanted to build a document and imaging solution into Medical Manager (and later into its Intergy product) that could support a variety of file types and standards without placing any limitations on its client practices. That’s when they discovered ImageGear.

One of ImageGear's biggest strengths is that it can support just about any sort of document out there. That was obviously one of the major drivers, and the fact that not only could it handle most document types, it could also handle diagnostic images.
