Cancer radiotherapie : journal de la Societe francaise de radiotherapie oncologique, 2008
Recent advances in radiation oncology are based on improvement in dose distribution thanks to IMRT and improvement in target definition through new diagnostic imaging such as spectroscopic or functional MRI or PET. However, anatomic variations may occur during treatment decreasing the benefit of such optimization.

A review of image-guided radiotherapy
Radiological Physics and Technology, 2009Image-guided radiotherapy (IGRT) is in the midst of a strong development and implementation cycle, stimulated by pioneering work performed in Japan. We present a review of the rationale, technology, and methodology of image guidance, as well as an overview of current work in IGRT at the Massachusetts General Hospital. The technology is rapidly evolving,

Cancer radiotherapie : journal de la Societe francaise de radiotherapie oncologique, 2017
The IGRT is described in its various equipment and implementation. IGRT can be based either on ionizing radiation generating 2D imaging (MV or kV) or 3D imaging (CBCT or MV-CT) or on non-ionizing radiation (ultrasound, optical imaging, MRI or radiofrequency). Adaptive radiation therapy is then presented in its principles of implementation. The function

Image guided radiation therapy (IGRT) is currently one of the most active research fields in medical physics. The recent development of high precision dose delivery techniques with high energy photon and hadron beams can only be fully exploited if we confidently know the shape and location of radiation targets and the organs at risk at the time of the ...

Advanced Image-Guided External Beam Radiotherapy
2008The goal of radiation therapy is to eradicate tumor stem cells while sparing healthy tissue. Therefore, the first aim must be to delineate tumor from healthy tissue. Advanced imaging techniques will enable one to reduce the uncertainty of microscopic extension of disease.

Image-guided radiotherapy: rationale, benefits, and limitations
The Lancet Oncology, 2006Technological advances have greatly enhanced the specialty of radiation oncology by allowing more healthy tissue to be spared for the same or better tumour coverage. Developments in medical imaging are integral to radiation oncology, both for design of treatment plans and to localise the target for precise administration of radiation.

A (short) history of image-guided radiotherapy
Radiotherapy and Oncology, 2008Progress in radiotherapy is guided by the need to realize improved dose distributions, i.e. the ability to reduce the treatment volume toward the target volume and still ensuring coverage of that target volume in all dimensions. Poor ability to control the tumour's location limits the accuracy with which radiation can be delivered to tumour-bearing ...

Physics Support of Image-guided Radiotherapy
Clinical Oncology, 2013Sir 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
2006Adaptive 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, 2007Intensity 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.
