Partitioning of multiple brain metastases improves dose gradients in single-isocenter radiosurgery
Johan Sundström, Anton Finnson, Elin Hynning +2
Background: A growing number of cancer patients with brain metastases can benefit from stereotactic radiosurgery (SRS) thanks to recent advances in systemic therapies. With an incr…
Shoot-through layers in upright proton arcs unlock advantages in plan quality and range verification
Erik Engwall, Victor Mikhalev, Johan Sundström +2
Background: Upright proton therapy with compact delivery systems has the potential to reduce costs for treatments but could also lead to broadening of the beam penumbra due to ener…
Efficient proton arc optimization and delivery through energy layer pre-selection and post-filtering
S. Wuyckens, V. Wase, O. Marthin +7
Proton arc therapy (PAT) has emerged as a promising approach for improving dose distribution, but also enabling simpler and faster treatment delivery in comparison to conventional…
Implications of Clinical Target Distribution Weighted Radiotherapy Optimization
Ivar Bengtsson, Anders Forsgren, Albin Fredriksson
Delineating and planning with respect to regions suspected to contain microscopic tumor cells is an inherently uncertain task in radiotherapy. The recently proposed \textit{clinica…
Distributed Objective Function Evaluation for Optimization of Radiation Therapy Treatment Plans
Felix Liu, Måns I. Andersson, Albin Fredriksson +1
The modern workflow for radiation therapy treatment planning involves mathematical optimization to determine optimal treatment machine parameters for each patient case. The optimiz…
Robust automated radiation therapy treatment planning using scenario-specific dose prediction and robust dose mimicking
Oskar Eriksson, Tianfang Zhang
Purpose: We present a framework for robust automated treatment planning using machine learning, comprising scenario-specific dose prediction and robust dose mimicking. Methods: The…
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…
Probabilistic dose prediction using mixture density networks for automated radiation therapy treatment planning
Viktor Nilsson, Hanna Gruselius, Tianfang Zhang +2
We demonstrate the application of mixture density networks (MDNs) in the context of automated radiation therapy treatment planning. It is shown that an MDN can produce good predict…
On Adaptation Cost and Tractability in Robust Adaptive Radiation Therapy Optimization
Michelle Böck
A framework for online robust adaptive radiation therapy (ART) is presented. This framework is designed to (i) handle interfractional geometric variations following a probability d…
On the Interplay between Robustness and Dynamic Planning for Adaptive Radiation Therapy
Michelle Böck, Kjell Eriksson, Anders Forsgren
Interfractional geometric uncertainties can lead to deviations of the actual delivered dose from the prescribed dose distribution. To better handle these uncertainties during treat…
Increased accuracy of planning tools for optimization of dynamic multileaf collimator delivery of radiotherapy through reformulated objective functions
Lovisa Engberg, Kjell Eriksson, Anders Forsgren
The purpose of this study is to examine in a clinical setting a novel formulation of objective functions for intensity-modulated radiotherapy treatment plan multicriteria optimizat…
Towards Robust Adaptive Radiation Therapy Strategies
Michelle Böck, Anders Forsgren, Kjell Eriksson +1
The authors propose robust adaptive strategies based on stochastic minimax optimization for a series of simulated treatments on a one-dimensional patient phantom. The plan applied…
Explicit optimization of plan quality measures in intensity-modulated radiation therapy treatment planning
Lovisa Engberg, Kjell Eriksson, Anders Forsgren +1
Conventional planning objectives in optimization of intensity-modulated radiotherapy treatment (IMRT) plans are designed to minimize the violation of dose-volume histogram (DVH) th…
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…
Necessary and sufficient conditions for Pareto efficiency in robust multiobjective optimization
Rasmus Bokrantz, Albin Fredriksson
We provide necessary and sufficient conditions for robust efficiency (in the sense of Ehrgott et al. (2014)) to multiobjective optimization problems that depend on uncertain parame…
Piezonuclear reactions - do they exist?
G. Ericsson, S. Pomp, H. Sjöstrand +1
In a number of recent articles in this journal F. Cardone and collaborators have claimed the observation of several striking nuclear phenomena which they attribute to "piezonuclear…
