[Conformal radiotherapy].

Progres en urologie : journal de l'Association francaise d'urologie et de la Societe francaise d'urologie, 1999
Conformal radiotherapy is a new irradiation technique made possible by technological improvements, especially progress in imaging and 3D dosimetry. By conforming the volume irradiated as closely as possible to the clinical anatomical target volume, conformal radiotherapy is designed to deliver a higher dose to the tumour volume, while more effectively ...

[Conformal radiotherapy: tomotherapy].

Cancer radiotherapie : journal de la Societe francaise de radiotherapie oncologique, 2001
Conformal radiation therapy allows the possibility of delivering high doses at the tumor volume whilst limiting the dose to the surrounding tissues and diminishing the secondary effects. With the example of the conformal radiation therapy used at the AZ VUB (3DCRT and tomotherapy), two treatment plans of a left ethmoid carcinoma will be evaluated and ...

Image guidance for precise conformal radiotherapy

International Journal of Radiation Oncology*Biology*Physics, 2003
To review the state of the art in image-guided precision conformal radiotherapy and to describe how helical tomotherapy compares with the image-guided practices being developed for conventional radiotherapy.Image guidance is beginning to be the fundamental basis for radiotherapy planning, delivery, and verification.

Stereotactically guided conformal radiotherapy for meningiomas

Radiotherapy and Oncology, 1999
Stereotactically guided conformal radiotherapy, (SCRT) is a high precision technique of conformal radiotherapy (RT) which reduces the volume of normal tissue irradiated compared to conventional RT and may lead to a reduction in long-term toxicity We describe the technique and the preliminary results in patients with inoperable, residual or recurrent ...

Conformal Proton Radiotherapy Planning

2000
Conformal radiotherapy planning tries to match a tumoricidal dose to the target volume, including a safety margin. At the same time this dose distribution must deliver a radiation dose as low as possible to normal or radio-sensitive tissues. Planning is thus one of the centre pieces of proton radiotherapy.

Clinical Implications of 3D-Conformal Radiotherapy

Oncology Research and Treatment, 2000
INTRODUCTION: Local tumor control in cancer patients is the major goal of radiation therapy. More than 10% of cancer patients die as a result of local failure with no evidence of metastatic disease. A local failure can represent the cause of metastastic progression.

Treatment planning for conformal stereotactic radiotherapy

Strahlentherapie und Onkologie, 1999
Due to three dimensional planning techniques it is possible to conform the high dose region precisely to a target volume inside the brain. Special patient fixation and positioning systems allow a high precision in repositioning of the patient thus allowing fractionated stereotactic radiotherapy.

Conformal radiotherapy of urinary bladder cancer

Radiotherapy and Oncology, 2004
Recent advances in radiotherapy (RT) are founded on the enhanced tumour visualisation capabilities of new imaging modalities and the precise deposition of individualised radiation dose distributions made possible with the new systems for RT planning and delivery.

Conformal radiotherapy, intensity-modulated radiotherapy and image-guided radiotherapy

2008
The aim of radiotherapy is to deliver the desired tumoricidal dose to the intended target as accurately and reliably as possible and avoid unnecessary dose to surrounding normal tissues. This principle was recognized when irradiation was utilized therapeutically over 100 years ago and has been the guiding force for development and refinement of modern ...

[Glossary of conformal radiotherapy].

Cancer radiotherapie : journal de la Societe francaise de radiotherapie oncologique, 1999
Most of the concepts and terms related to conformal radiotherapy were produced by English-speaking authors and eventually validated by international groups of experts, whose working language was also English. Therefore, a significant part of this literature is poorly accessible to the French-speaking radiation oncology community.
