The IMV Medical Information Division (formerly TMG) division builds "census databases" that track medical imaging laboratories in both the hospital and independent lab setting. Disciplines covered include CT, MRI, nuclear medicine, angiography, fluoroscopy, diagnostic ultrasound, cardiac catherization, echocardiography, radiation oncology, PET, electrophysiology and PACS. Information collected includes multiple variables such as: procedure volume by anatomical category, installed base, equipment buying plans, image networking plans, contrast media utilization, staffing levels and operations budgets.
