Figure 10. Distribution of scattered radiation from digital acquisition on the 30° right anterior oblique (RAO) 25° caudal projection at 69 kVp. The radial axis shows the dose in µGy min^–1, whereas the ionization chamber position is indicated on the circumference. The figure shows the patient position from above, and the arrow shows the direction of the primary beam. Data for points not measured at 90°, 180° and 150° at 60 cm have been interpolated.
