Physics Support of Image-guided Radiotherapy

Clinical Oncology, 2013
Sir d The implementation of image-guided radiotherapy (IGRT) into routine clinical practice has been far more rapid than other novel technologies such as intensity-modulated radiotherapy or particle therapy. This may be due in part to the reduced physicist resources required to commission commercial systems and the inherent multidisciplinary nature of ...

Image-Guided/Adaptive Radiotherapy

2006
Adaptive radiotherapy system is designed to systematically manage treatment feedback, planning, and adjustment in response to temporal variations occurring during the radiotherapy course. A temporal variation process, as well as its subprocess, can be classified as a stationary random process or a nonstationary random process.

[Image-guided radiotherapy for prostate cancer].

Aktuelle Urologie, 2007
Intensity modulated radiotherapy (IMRT) has improved the capability to apply geometrically individualised high radiotherapy doses to the prostate bed, prostate and seminal vesicles. A high risk of geometrical miss with conformal methods, however, has been documented for mobile targets such as the prostate.

Image guided radiotherapy for prostate cancer.

Bulletin du cancer, 2008
The purpose of external beam radiotherapy is to sterilize malignant tumours and at the same time to avoid complications by radiation injury to the surrounding healthy tissues. Modern radiation techniques in recent years have allowed to safely escalate the dose by approximately 10% for the treatment of prostate cancer, resulting in a disease control ...

Helical Tomotherapy: Image-Guided and Adaptive Radiotherapy

2011
Helical tomotherapy is a treatment device that is designed to deliver intensity-modulated radiation therapy treatments. Helical tomotherapy systems have been used to treat a wide spectrum of anatomical sites. In addition to its unique delivery technique, the capability to obtain megavoltage-based CT (MVCT) images is highly integrated into the system's ...

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 ...

[Image-guided and adaptive radiotherapy].

Cancer radiotherapie : journal de la Societe francaise de radiotherapie oncologique, 2012
Image-guided radiotherapy (IGRT) aims to take into account anatomical variations occurring during irradiation by visualization of anatomical structures. It may consist of a rigid registration of the tumour by moving the patient, in case of prostatic irradiation for example.

Image-guided (4D) radiotherapy.

2007
Improper knowledge of the patient's anatomy and position during the course of therapy has always been a major source of concern in radiation therapy potentially compromising the clinical results by insufficient dose coverage of the target volume and/or overdose of normal tissues.
