Background: Broca’s and Wernicke’s areas, which are important language areas of brain, are commonly irradiated in patients with right frontal lobe glioblastomamultiforme (GBM). We aimed to compare two different treatment planning techniques in terms of the doses in the Broca’s and Wernicke’s areas for the patients with right frontal GBM. Materials and Methods: Two differ...

This paper is concerned with modeling planning problems involving uncertainty as discrete-time, nite-state stochastic automata. Solving planning problems is reduced to computing policies for Markov decision processes. Classical methods for solving Markov decision processes cannot cope with the size of the state spaces for typical problems encountered in practice. As an alternative, we investiga...

background: we have validated the monitor unit calculations from a commercially available treatment planning system (tps) for three intensity modulated radiotherapy (imrt) planning techniques for tangential breast irradiation by using ionization chamber measurements. materials and methods: treatment plans were generated for forty-two breast patients by a forward planned field in field technique...

an important need in radiation therapy is a fast and accurate treatment planning system. this system using ct data and characteristics of the radiation beam, calculates the dose in all points of the patient’s volume. two main factors in planning system are “accuracy” and “speed”. according to these factors, various generation of treatment planning systems are developed.   this article is the re...

The use of small aerial vehicles (SAVs) such as quadrotors for inspection and surveillance applications both indoors and out is well established, but motion planning techniques are needed which can be calculated in real-time and which result in provably safe vehicle motion in tightly constrained 3D environments. Applied to small quadrotor helicopters, our planning algorithm combines Probabilist...
