What We Do?

Setting up a fully functional software infrastructure for any medical institute is a daunting process. Another challenge faced by medical institutes is the interoperability enabling seamless data exchange within various departments. At Raster, we believe in the power of open source and interoperability to achieve lower infrastructure cost. Pioneers in PACS, Raster has ventured into the Internet of Medical Things (IoMT) connecting the various medical devices, software applications and healthcare systems and services.

Our softwares applications are powerful, flexible, and scalable to meet the needs of any business. We have always been innovators and pioneers, working with great leaders.
