摘要: Flash is a specified function in TomoDirect that enables beam expansion by opening additional leaves to the target. This study assessed theoretical dose distribution resulting from breast irradiation using TomoDirect. A cylindrical phantom enabled of was used for verifying effect planning target volume (PTV) contouring and Flash. total 18 Gy 10 fractions were prescribed PTV. Five PTVs then created Contracting this contour 0, 1, 2, 3, 4 5 mm, giving PTV-x. ±x defined x (number) leaves. The air compared with each set-up error 5, 15 respectively. minimum PTV PTV-1 PTV-3 increased 13.88 15.86 Gy. In contrast, Dmin PTV-4 PTV-5 17.80 98.88% prescription dose. Without Flash, when 5-, 10- 15-mm errors applied PTV, relative doses 87.88, 23.73 7.94% observed, However, which equal usual margin 1.875 cm, 104.24% ± 0.30% irrespective (5 mm mm). useful countervailing cancer patients who receive
