Incorporating multi-leaf collimator leaf sequencing into iterative IMRT optimization.
Intensity modulated radiation therapy (IMRT) treatment planning typically considers beam optimization and beam delivery as separate tasks. Following optimization, a multi-leaf collimator (MLC) or other beam delivery device is used to generate fluence patterns for patient treatment delivery. Due to limitations and characteristics of the MLC, the deliverable intensity distributions often differ f...
متن کاملOptimal Multileaf Collimator Leaf Sequencing in IMRT Treatment Planning
We consider a problem dealing with the efficient delivery of Intensity Modulated Radiation Therapy (IMRT) to individual patients. IMRT treatment planning is usually performed in three phases. The first phase determines a set of beam angles through which radiation is delivered, followed by a second phase that determines an optimal radiation intensity profile (or fluence map). This intensity prof...
متن کاملA Novel Transformer-Based Single-to-Three Phase Conversion Technique Using Rotating Magnetic Field Theory
This paper presents a new single to three phase converter using rotating magnetic field transformer. Conventional transformers have been used in many converters aiming at supplementary improvements and they usually have no critical effect on the conversion technique. In this paper, the conversion technique is based on a special rotating magnetic field transformer in which there are two windings...
متن کاملNeutron beam characteristics from 50 MeV protons on beryllium using a continuously variable multi-leaf collimator.
The dose distributional properties of a p(50) Be neutron beam using a continuously variable multi-leaf collimator are presented and compared with a 6 MV photon beam. The differences in physical dose delivery between these two radiation modalities are generally insignificant for radiation therapy, and stringent comparisons of neutron and photon treatments should therefore be possible. The flexib...

it was assumed that, although there were small discrepancies between the plans and all of the doses were under the critical dosages stated for rectum, bladder and femoral heads for each technique, the doses given to the critical organs were higher with the MLC technique. Regarding the late toxicity and the critical organ doses, each of these shaping methods is suitable for the definitive irradi...
