Fig. 3From: Patient organ and effective dose estimation in CT: comparison of four software applicationsOrgan dose per volume computed tomography dose index (CTDIvol) unit, obtained simulating the CT maxillofacial protocol with CT-Expo, NCICTX, NCICT, and Virtual Dose, using a male and a female phantom. These values are dose coefficients, obtained as organ dose (mGy) and CTDIvol (mGy) ratio. Pituitary gland and lens are completely irradiated. Only NCICTX and NCICT consider the pituitary gland. Virtual Dose does not consider lensBack to article page
