Cranio-caudal Fixation Units

For diagnostic imaging, NORAS MRI products has developed special fixation units to immobilize the breast. With the Cranio-caudal Fixation Units you can optionally immobilize one or both breasts at the same time. Using this device, one can save up to 50% of scanning time, while reducing non-desired motion artifacts.
