Relationship between CTDI values and measured Peak Skin Dose (PSD)

July 16, 2013
Author(s)
Ronaldo Minniti, Hugo de las Heras Gala, Sean Wilson, Chad Mitchell, Marlene Skopec, Claudia Brunner, Kish Chakrabarti
In this work we relate the CT dose index volume (CTDIvol) readily displayed in all CT units with an actual Peak Skin Dose (PSD) value. Measurements of the CTDI and skin exposure were performed simultaneously using an ionization chamber and radiochromic
