doi: 10.1117/1.JMI.4.3.031212
Figure Lengend Snippet: Summary of the three parameters D eq , L eq , and α from the AAPM fit in (a) Toshiba MSCT scanner and (b) i-CAT Next Generation dental CBCT scanner. (a) For each patient group, the D eq values from thimble chamber measurements are very close to each other, with the highest being present in the child head phantom and the lowest in the adult head phantom. The pencil chamber measurements generate larger D eq , α , and L eq values. (b) The AAPM method and the two Sedentex methods result in similar D eq , α , and L eq values for each patient group.
