Computerized Imaging Reference Systems, Inc (CIRS)

CIRS is recognized worldwide as a leader in the manufacture of tissue equivalent phantoms for densitometry, calibration, quality control, research and training in medical imaging and radiation therapy. CIRS is one of few companies that specialize exclusively in the design, development and manufacture of tissue equivalent phantoms for all imaging modalities and the only company offering “multi-modality phantoms” that are tissue equivalent under X-ray, Ultrasound and MRI combined. CIRS was founded in 1982 by Dr. Elias Zerhouni. His mission was to create a reference phantom that would enable Computed Tomography Scanners to accurately differentiate benign from malignant lung tumors. His patented “Lung Nodule Reference Simulator” minimized the need for costly and often unnecessary lung thoracotomies. Other products followed including a CT phantom for bone mineral density evaluation and phantoms for evaluating image quality of mammography systems.
