Iterative Reconstruction in CT Evolves for Lower Dose, Increased Clarity
Radiologists have been struggling to balance image noise with radiation dose in computed tomography (CT) scans for decades. But the competition just went up a notch (or perhaps many notches) with the recent FDA approval of GE Healthcare’s Model Based Image Reconstruction (MBIR) technology, Veo.

The result of their program: a 29 percent drop in dose exposure.
