Dosimetry

Dosimetry using average-sized phantoms leads to considerable errors The use of non-size-dependent reference phantoms to calculate CT dose can lead to errors in calculating the radiation received by a patient, according to an article published in the American Journal of Roentgenology. Using data from the National Lung Screening Trial, researchers found using an average height and weight to calculate dose can lead to errors of up to 200 percent when compared with a more accurate estimate using a particular patient’s height and weight.

The U.S. Food and Drug Administration (FDA) has approved the use of a wireless ultrasound scanner, a device that can help physicians complete high-quality scans quickly when they have limited access to traditional machines. The ultrasound, made by Clarius Mobile Health, a digital healthcare company in Canada, is a pocket-sized scanner that wirelessly connected to Apple and Android devices, according to a statement from the company.
