Use of CTDI in comparative dosimetry
does my new scanner give less dose than my old one ?
what if I use 140 kV, 130 mAs, 5 mm, pitch 1
instead of 120 kV, 200 mAs, 2.5 mm, pitch 1.5 ?
for the same scanned length
but on another protocol we want to change the scanned lengths as well as some of the parameters….
