1. Image Distance Learning for Probabilistic Dose–Volume Histogram and Spatial Dose Prediction in Radiation Therapy Treatment Planning
University essay from KTH/Matematisk statistikAbstract : Construction of radiotherapy treatments for cancer is a laborious and time consuming task. At the same time, when presented with a treatment plan, an oncologist can quickly judge whether or not it is suitable. This means that the problem of constructing these treatment plans is well suited for automation. READ MORE

2. Automation of robust Pareto front-based radiotherapy treatment planning for prostate cancer patients
University essay from Lunds universitet/SjukhusfysikerutbildningenAbstract : Purpose/objective The main objective was to create a software that automates the process of creating treatment plans used for Pareto front-based dose planning for prostate cancer patients. A second objective/purpose was to add a robustness test to this program to evaluate the effect of prostate movements on the treatment plans. READ MORE

3. Direct optimization of dose-volume histogram metrics in intensity modulated radiation therapy treatment planning
University essay from KTH/Skolan för teknikvetenskap (SCI)Abstract : 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.
