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.

Hypothesis and fact get mixed up in radiation debate
March 8, 2010
When it comes to the sizzling hot topic of carcinogenesis and diagnostic radiation, it is crucial to differentiate hypothesis from scientific fact, maintain a sober mind, and separate science from politics and economics.
Vendors look to mathematical solutions to minimize CT dose, improve safety
March 5, 2010
Radiology is a medical specialty created by a fertile marriage between biology and physics. But it is an entirely different academic discipline that is the focus of the research by major vendors of CT technology on show this year at the ECR’s technical exhibition. Their studies have centered on the subject that the illustrious 19th century German scientist Carl Friedrich Gauss called “the queen of sciences”: mathematics.
We have to calm dose hysteria…RIGHT NOW!

Americans are scared. Some are frightened out of their wits. A radiologist recently told me about a patient with terminal pancreatic cancer who refused a CT ordered by his oncologist. Why? The patient said he was worried about radiation.
Siemens unveils CT dose reduction
December 4, 2009
New software shown by Siemens at the RSNA meeting promises to cut patient exposure to x-rays by as much as 60% for a wide range of CT applications.
