Focal Point: CT Dose
Sponsored by Siemens
 

Vendors continue to improve strategies for reducing dose exposures from x-ray based imaging. This comes none too soon because the risk from medical imaging-based radiation exposure has captured the imagination of the public, so much so that there are reports patients are avoiding needed CT scans out of fear of the radiation. Below you find perspectives on the social aspects of the issue along with more technical reports on how vendors are tackling the dose reduction challenge.
