CONFORMAL RADIOTHERAPY FOR BRAIN TUMOURS

Hematology/Oncology Clinics of North America, 2001
The technical improvements of three-dimensional conformal radiotherapy can decrease the toxicity of brain treatment to acceptable levels. The adoption of the technique by more centers would allow for the potential advantages of three-dimensional radiotherapy to be employed in a greater number of patients.

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.

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.

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 ...

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 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.

Conformal Photon-Beam Radiotherapy of Prostate Carcinoma

European Urology, 2002
Three-dimensional conformal radiotherapy is the recommended radiation technique for localized or locally advanced prostate cancer. In the past decades, external beam irradiation procedures have evolved in the context of technical developments of radiation and imaging equipment.

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].

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 ...
