Image-Processing Algorithm Reduces CT Radiation Dose up to 95 Percent
One of the scientists explains how they overcame the image-quality drawbacks of low-dose CT scans:
“When we use very low doses, the noise gets so high that it’s hard to tell what you are seeing,” said Juan Carlos Ramirez Giraldo. “With this algorithm, we’re trying to maintain both the image quality, so that a doctor can recognize the anatomic structures, and the functional information, which is conveyed by analyzing the flow of the contrast agent over the many low dose scans.”
Amazing that a change in software can, in effect, decrease radiation exposure by that much.
