From: Patient organ and effective dose estimation in CT: comparison of four software applications
Organ dose per volume computed tomography dose index (CTDIvol) unit, obtained simulating the CT abdomen-pelvis protocol with CT-Expo, NCICTX, NCICT, and Virtual Dose, using a male and female phantom. These values are dose coefficients, obtained as organ dose (mGy) and CTDIvol (mGy) ratio. Liver, stomach, colon, bladder, prostate/uterus, gonads, spleen, pancreas, adrenals, kidneys, small intestine, gallbladder, and rectum are completely irradiated. Only NCICTX and NCICT consider trachea and rectum. CT-Expo considers the breasts only for the female phantom
