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,

The role of radiation therapy (RT) in the treatment of liver malignancies has historically been low, in part due to challenges in delivering ablative doses of RT safely while respecting the radiation dose limits of numerous normal tissues in the upper abdomen, including the liver itself. Challenges to the routine use of RT to treat hepatic malignancies

Innovations in image-guided radiotherapy
Nature Reviews Cancer, 2007The limited ability to control for the location of a tumour compromises the accuracy with which radiation can be delivered to tumour-bearing tissue. The resultant requirement for larger treatment volumes to accommodate target uncertainty restricts the radiation dose because more surrounding normal tissue is exposed. With image-guided radiotherapy (IGRT)

Dynamic targeting image-guided radiotherapy
Medical Dosimetry, 2006Volumetric imaging and planning for 3-dimensional (3D) conformal radiotherapy and intensity-modulated radiotherapy (IMRT) have highlighted the need to the oncology community to better understand the geometric uncertainties inherent in the radiotherapy delivery process, including setup error (interfraction) as well as organ motion during treatment ...

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 ...

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.

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 ...

IMAGE-GUIDED MOTION ADAPTATION IN RADIOTHERAPY
2007 4th IEEE International Symposium on Biomedical Imaging: From Nano to Macro, 2007In this paper we review the engineering problems and solutions for real-time spatial tracking of radiotherapy treatment sites during free breathing. These techniques will allow the reduction and possible elimination of dose-limiting motion margins in external-beam radiation delivery ...

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 ...
