VirtualDose utilizes computer models of different body types to advise physicians on which CT scanning configurations will produce the least amount of radiation
X-ray computed tomography – or CT – scanners are designed with people of an average build in mind. When obese patients require a CT scan, the additional layers of body fat will produce blurry images if the scanner’s regular settings are used. Clinicians typically address this problem by turning up the power of the scanner. Unfortunately, doing so results in overweight patients receiving higher-than-normal doses of radiation. A new computer modeling system developed at New York’s Rensselaer Polytechnic Institute, however, could help bring those levels down.
