摘要: Several recently published papers deal with the so-called inverse problem of radiation therapy (Brahme 1988; Webb 1989; Barth 1990; Goitein Lind and Kallman Bortfeld et al. 1990a). Most authors define this as directly determining treatment parameters on basis desired dose distribution, which is process to that in conventional radiotherapy planning. Usually, term used conjunction a new technique using modulated irradiation fields, where are modulation profiles for each beam direction. Also, context, justified because calculating principle matrix inversion problem.
