Peak Skin and Eye Lens Radiation Dose From Brain Perfusion CT: CTDIvol and Monte Carlo Based Estimations

European Journal of Radiology, 2020
To quantify the eye lens, peak skin and brain doses associated with head CT perfusion exam by means of thermoluminescent dosimeters (TLDs) measurements in a cadaver and compare them to Monte Carlo (MC) dose estimations as well as to the CTDIvol.18 TLDs were inserted in the brain, skin, and eye lenses of a female cadaver head, who underwent a CT brain ...

MO-D-134-11: Anomalous Scanner-Reported Values of CTDIvol

Medical Physics, 2013
Purpose: Significant anomalies in scanner reported values of CTDIvol for stationary table protocols (with aberrant, elevated values of CTDIvol up to 300 % higher than the actual dose to the phantom), have been observed; well beyond the typical accuracy expected of CTDIvol as a phantom dose.

Stationary Table CT Dosimetry and Anomalous Scanner-Reported Values of CTDIvol

Medical Physics, 2014
Anomalous, scanner-reported values of CTDIvol for stationary phantom/table protocols (having elevated values of CTDIvol over 300% higher than the actual dose to the phantom) have been observed; which are well-beyond the typical accuracy expected of CTDIvol as a phantom dose.
