چکیده

Aperture-based inverse planning (ABIP) for intensity modulated radiation therapy (IMRT) treatment planning starts with external radiation fields (beams) that fully conform to the target(s) and then superimposes sub-fields called segments to achieve complex shaping of 3D dose distributions. The segments’ intensities are determined by solving a feasibility problem. The least-intensity feasible (LIF) solution, proposed and studied here, seeks a feasible solution closest to

Direct Aperture Optimization for Intensity Modulated Radiation Therapy: Two Calibrated Metaheuristics and Liver Cancer Case Study

Integrated treatment planning for cancer patients has high importance in intensity modulated radiation therapy (IMRT). Direct aperture optimization (DAO) is one of the prominent approaches used in recent years to attain this goal. Considering a set of beam directions, DAO is an integrated approach to optimize the intensity and leaf position of apertures in each direction. In this paper, first, ...

Sparse Solution for the Intensity-Modulated Radiotherapy Problem Using Conic Programming

We address the problem of planning an effective IMRT (Intensity Modulated Radiotherapy) treatment for cancer. IMRT is a modern method of radiotherapy. It irradiates cancerous tissues by administering lethal dose of radiation to those cells, while sparing the healthy tissues. This method’s greatest advantage is the large degree of freedom which it allows the treatment planning, but it is also it...
