Intuitive Molecular Imaging: PET/CT SPECT/CT fusion and NM and gated cardiac image processing.

For over fifteen years Convergent Imaging Solutions has been providing molecular imaging software solutions to physicians worldwide. We offer thick and thin client PET/CT, SPECT/CT, PET/MR image fusion and 3D lesion quantification, as well as nuclear medicine processing (gastric, renal, gallbladder, lung, MUGA). We have diligently incorporated years of user feedback into our products, creating a highly flexible and user customizable experience. In addition, we are integrated with and market the Cedars Sinai gated SPECT and NeuroQ brain quantification packages.

From our development base in Ottawa, Canada, and with our PACS partners, we have deployed solutions worldwide, with installations in leading institutions in the United States, Canada, Australia and New Zealand.
