AbstractAbstract
[en] This paper presents an estimate of the effective dose from CTDIvol for exams of skull and abdomen in adult patients. Thereafter, measurements were taken of CTDI using an ionization chamber type pencil (Radcal Corportation, model 10 x 5 - 3CT) and cylindrical phantom of PMMA equivalent to regions of the skull (diameter = 16 cm) and abdomen (diameter = 32 cm). The results of effective dose for abdomen varied between 7,3 and 12,1 mSv and for skull between 1,4 and 5,0 mSv. Comparing with the literature data, for abdomen exams between 5 and 7 mSV and skull exams between 1 and 2 mSv, it is shown that it is possible to optimize these protocols, aiming to reduce the doses to patients
