摘要

The effects of five filtrations on dose reduction and image qualityin paediatric chest radiography with a high voltage technique are presented. The radiographs were performed using a Sieregraph unit )siemens) with 3.5 mm Al of primary total filtration, and added: 1 mm Al ＋0.1 mm 'Cu, 1 mm Al＋0.2 mm Cu, 4 mm Al, 4 mm Al＋0.1 mm Cu. The entrance air kerma (including backscatter) for each child examined was measured using TLD-100, and the parameters of expsoure were recorded. The absorbed organ doses and effective doses were calcualted using Monte Carlo simulation.
