1. The effect of rotation from a primary LAO or RAO angle on PSD for female patients: (A) primary 30° LAO projection; (B) primary 30° RAO projection and (C) primary 60° LAO projection.
The effect of rotation from a primary LAO or RAO angle on PSD for female patients: (A) primary 30° LAO projection; (B) primary 30° RAO projection and (C) primary 60° LAO projection. Results of CRA/CAU rotation from an initial 30° or 60° LAO projection were nearly identical to CRA/CAU rotation from a PA projection and are not shown. Vertical bold lines indicating the AAO. The results for each format group representing the X-ray field format and size from the group that required the largest AAO (AAO, angle to avoid overlap; PSD, peak skin dose; CAU, caudal; CRA, cranial; LAO, left anterior oblique; RAO, right anterior oblique).
