[Study of a radiation technic with an anterior mantle-shaped field and 10 MV photons]

The authors present a preliminary dosimetry study of 10 MV X-rays for irradiation technique with only one anterior mantle-field. The results of the studied beam for SSD = 120 cm are: 40 X 40 cm2 fields, build-up at 2.5 cm, penumbra (85% divided by 15%) variable between 8 divided by 9 mm, 50% of the dose at depth of 18 cm, homogeneity +/- 4%. These dosimetry results are suitable for beginning the clinical research.
