A and A': focus of lateral and undercouch tubes, respectively, the latter being rotated in this case from pure posteroanterior to 21 degrees LAO. The former presents a left lateral (LLAT) view. B and B' dose–area product meter positions at 20 cm from the focus. C: lead equivalent glass (50 x 40 x 0.1 cm3) with curtain attached below (50 x 35 x 0.05 cm3), at 8 cm from the lateral focus. D: cardiologist (Adam phantom, 70.6 kg, length 170 cm). The arrow indicates the position of the personal dosimeter (EPD). E: patient (here male, 5-year-old MIRD phantom, 18.8 kg, length 109 cm) with circumference of the heart shown. For lateral exposure the arms are removed (broken lines). The whole is enclosed in an air-filled box.
