Measurement of CT radiation beam width with a pencil ionization chamber and radiopaque mask
This study demonstrates that radiation beam widths of fan beam CT scanners can be measured using the ionization chamber-radiopaque mask method with an RMS accuracy of better than 0.5 mm. We demonstrate the method is applicable to nominal beam widths ranging from 1 to 40 mm.
