Radiobiology for IMRT

2015
Since the dose delivery pattern is different between intensity-modulated radiotherapy (IMRT) and conventional radiation, radiobiological assessment of the physical dose delivered by IMRT is considered necessary. In IMRT, the daily dose is usually given intermittently over a time longer than that used in conventional radiotherapy.

IGRT for IMRT

2015
Progress of radiation therapy technologies has enabled delivery of higher doses of radiation more precisely, resulting in improvement of the clinical outcomes of radiation therapy and of the quality of life (QOL) of the patients. Among the modern radiation therapy techniques, intensity-modulated radiation therapy (IMRT) has been established as an ...

Comments on ‘Single-Arc IMRT?’

Physics in Medicine and Biology, 2009
We read with interest the article titled 'Single-Arc IMRT?' (Bortfeld and Webb 2009 Phys. Med. Biol. 54 N9-20) and feel it imperative to draw the attention of your readers to comments suggesting that the authors may not be fully aware of current developments in this field.

IMRT national audit in Portugal

Physica Medica, 2019
The IAEA newly developed "end-to-end" audit methodology for on-site verification of IMRT dose delivery has been carried out in Portugal in 2018. The main goal was to evaluate the physical aspects of the head and neck (H&N) cancer IMRT treatments. This paper presents the national results.All institutions performing IMRT treatments in Portugal, 20 out of

On the degeneracy of the IMRT optimization problem

Medical Physics, 2002
One approach to the computation of photon IMRT treatment plans is the formulation of an optimization problem with an objective function that derives from an objective density. An investigation of the second‐order properties of such an objective function in a neighborhood of the minimizer opens an intuitive access to many traits of this approach.

History of IMRT

2015
The goal of the intensity-modulated radiation therapy (IMRT) process is to deposit a custom three-dimensional dose distribution into the target volume of a patient with extreme accuracy and precision. Computer optimization can generate treatment plans consisting of spatially nonuniform radiation beams that produce a relatively uniform dose distribution

Principles of IMRT

2015
Although the goals of intensity-modulated radiation therapy (IMRT) are the same as those of conventional treatments (maximize dose to target structures while minimizing dose to nearby normal tissues), some significant differences are present in the treatment planning and delivery processes.
