The Technique of Intensity-Modulated Radiotherapy in the Treatment of Cholangiocarcinoma

Tumori Journal, 2007
Aims and background Conventional radiotherapy in inoperable cholangiocarcinoma is limited by radiotolerance of the surrounding tissues. The aim of our dosimetric study was an evaluation of intensity-modulated radiotherapy in the treatment of inoperable bile duct carcinoma.

Comparison of the incidence of osteoradionecrosis with conventional radiotherapy and intensity‐modulated radiotherapy

Head & Neck, 2016
AbstractBackgroundModern techniques of radiotherapy are supposed to decrease the incidence of osteoradionecrosis of the mandible (ORNM). The purpose of this study was to compare the incidence of ORNM after intensity‐modulated radiotherapy (IMRT) in comparison to conventional 3D conformal radiotherapy techniques (conventional RT).MethodsWe conducted a ...

Intensity modulated radiotherapy

2012
Intensity-modulated radiotherapy (IMRT) is a radiation delivery technique that allows “dose sculpting” to improve target coverage while sparing normal tissues. In an IMRT plan, the number of photons delivered (or “fluence”) varies within a field. Such variability can be used to avoid normal structures with lower radiation tolerance than the cancer and ...

The Implementation of Intensity-modulated Radiotherapy in the UK

Clinical Oncology, 2010
Radiotherapy in the UK lags behind that in much of Europe in terms of both the low proportion of cancer patients gaining access to treatment and the long waiting times [1] and [2]. The technical quality of radiotherapy is also a cause for concern.

Exploration of tradeoffs in intensity-modulated radiotherapy

Physics in Medicine and Biology, 2005
The purpose of this study is to calculate Pareto surfaces in multi-criteria radiation treatment planning and to analyse the dependency of the Pareto surfaces on the objective functions used for the volumes of interest. We develop a linear approach that allows us to calculate truly Pareto optimal treatment plans, and we apply it to explore the tradeoff ...

Intensity-modulated radiotherapy of the female breast

Medical Dosimetry, 2002
Current methods for intensity-modulated radiotherapy (IMRT) in breast cancer use forward planning based on equivalent radiological path length to design intensity modulated tangential beams. Compared to conventional tangential techniques, dose reduction of organs at risk is limited using these techniques.
