Probabilistic Pareto plan generation for semiautomated multicriteria radiation therapy treatment planning

Tianfang Zhang, Rasmus Bokrantz, Jimmy Olsson

Objective: We propose a semiautomatic pipeline for radiation therapy treatment planning, combining ideas from machine learning-automated planning and multicriteria optimization (MC…

Direct optimization of dose-volume histogram metrics in radiation therapy treatment planning

Tianfang Zhang, Rasmus Bokrantz, Jimmy Olsson

We present a method of directly optimizing on deviations in clinical goal values in radiation therapy treatment planning. Using a new mathematical framework in which metrics derive…

Probabilistic feature extraction, dose statistic prediction and dose mimicking for automated radiation therapy treatment planning

Tianfang Zhang, Rasmus Bokrantz, Jimmy Olsson

Purpose: We propose a general framework for quantifying predictive uncertainties of dose-related quantities and leveraging this information in a dose mimicking problem in the conte…

A similarity-based Bayesian mixture-of-experts model

Tianfang Zhang, Rasmus Bokrantz, Jimmy Olsson

We present a new nonparametric mixture-of-experts model for multivariate regression problems, inspired by the probabilistic k-nearest neighbors algorithm. Using a conditionally spe…

Dynamic conformal arcs for lung stereotactic body radiation therapy: a comparison with volumetric modulated arc therapy

Rasmus Bokrantz, Minna Wedenberg, Peter Sandwall

This study evaluates dynamic conformal arc (DCA) therapy as an alternative to volumetric modulated arc therapy (VMAT) for stereotactic body radiation therapy (SBRT) of lung cancer.…

The scenario-based generalization of radiation therapy margins

Albin Fredriksson, Rasmus Bokrantz

We give a scenario-based treatment plan optimization formulation that is equivalent to planning with geometric margins if the scenario doses are calculated using the static dose cl…
