1. Direct optimization of dose-volume histogram metrics in intensity modulated radiation therapy treatment planning
Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)Sammanfattning : In optimization of intensity-modulated radiation therapy treatment plans, dose-volumehistogram (DVH) functions are often used as objective functions to minimize the violationof dose-volume criteria. Neither DVH functions nor dose-volume criteria, however,are ideal for gradient-based optimization as the former are not continuously differentiableand the latter are discontinuous functions of dose, apart from both beingnonconvex.
