An Ensemble Approach to Knowledge-Based Intensity-Modulated Radiation Therapy Planning

Knowledge-based planning (KBP) utilizes experienced planners' knowledge embedded in prior plans to estimate optimal achievable dose volume histogram (DVH) of new cases. In the regression-based KBP framework, previously planned patients' anatomical features and DVHs are extracted, and prior knowledge is summarized as the regression coefficients that transform features to organ-at-risk DVH predic...

Iterative Approach for Automatic Beam Angle Selection in Intensity Modulated Radiation Therapy Planning

Introduction: Beam-angle optimization (BAO) is a computationally intensive problem for a number of reasons. First, the search space of the solutions is huge, requiring enumeration of all possible beam orientation combinations. For example, when choosing 4 angles out of 36 candidate beam angles, C36 = 58905 possible combinations exist.  Second, any change in a   beam 4 config...

An Automated Intensity-Modulated Radiation Therapy Planning System

We design and implement an intensity-modulated radiation therapy (IMRT) plan generation technology that effectively and efficiently optimizes beam geometry as well as beam intensities. Our approach is based on an existing linear programming based fluence map optimization model that approximates dose volume requirements using conditional value-at-risk (C-VaR) constraints. We show how the paramet...

Integer Programming Applied to Intensity-Modulated Radiation Therapy Treatment Planning

In intensity-modulated radiation therapy (IMRT) not only is the shape of the beam controlled, but combinations of open and closed multileaf collimators modulate the intensity as well. In this paper, we offer a mixed integer programming approach which allows optimization over beamlet fluence weights as well as beam and couch angles. Computational strategies, including a constraint and column gen...
