  1. Beam angle optimization in IMRT: are we really optimizing what matters?. Intensity-modulated radiation therapy (IMRT) is a modern radiotherapy modality that uses a multileaf collimator to enable the irradiation of the patient with nonuniform maps of radiation from a set of distinct beam irradiation directions. The aim of IMRT is to eradicate all cancerous cells by irradiating the tumor with a prescribed dose while simultaneously sparing, as much as possible, the neighb. 2018.

  4. Automated fluence map optimization based on fuzzy inference systems. The planning of an intensity modulated radiation therapy treatment requires the optimization of the fluence intensities. The fluence map optimization (FMO) is many times based on a nonlinear continuous programming problem, being necessary for the planner to define a priori weights and/or lower bounds that are iteratively changed within a trial-and-error procedure until an acceptable plan is reache. 2016.

  5. SPIDERplan: A tool to support decision-making in radiation therapy treatment plan assessment. Aim In this work, a graphical method for radiotherapy treatment plan assessment and comparison, named SPIDERplan, is proposed. It aims to support plan approval allowing independent and consistent comparisons of different treatment techniques, algorithms or treatment planning systems. Background Optimized plans from modern radiotherapy are not easy to evaluate and compare because of their inherent. 2016.

  6. A derivative-free multistart framework for an automated noncoplanar beam angle optimization in IMRT. The inverse planning of an intensity-modulated radiation therapy (IMRT) treatment requires decisions regarding the angles used for radiation incidence, even when arcs are used. The possibility of improving the quality of treatment plans by an optimized selection of the beam angle incidences-beam angle optimization (BAO)-is seldom done in clinical practice. The inclusion of noncoplanar beam inciden. 2016. Rocha, Humberto; Dias, Joana; Ventura, Tiago; Ferreira, Brígida; Lopes, Maria do Carmo; BC Ferreira. http://hdl.handle.net/10316/44494.
