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: 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 ...

Three-dimensional planning and conformal radiotherapy

1997
The value of three-dimensional (3D) planning and conformai radiotherapy in the treatment of soft tissue sarcoma has already been established [1]. In a previous volume on soft tissue sarcomas in this series (Cancer Treatment and Research), Suit and Willett succinctly described the sequential steps required for optimal radiation therapy [2].

[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.

[Conformal index and radiotherapy].

Cancer radiotherapie : journal de la Societe francaise de radiotherapie oncologique, 2004
Goal of radiotherapy is to treat patient with the best therapeutic ratio, i.e. the highest local control and the lowest toxicity rates. The conformal approach, three-dimensional conformal radiotherapy or intensity-modulated radiotherapy, is based on imageries, up-dated 3-D treatment planning systems, immobilization systems, restricted quality assurance

[Dosimetric evaluation of conformal radiotherapy: conformity factor].

Cancer radiotherapie : journal de la Societe francaise de radiotherapie oncologique, 2000
The aim of three-dimensional conformal therapy (3DCRT) is to treat the Planning Target Volume (PTV) to the prescribed dose while reducing doses to normal tissues and critical structures, in order to increase local control and reduce toxicity. The evaluation tools used for optimizing treatment techniques are three-dimensional visualization of dose ...

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 ...

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.
