When Should IGRT Be Done?

2018
The therapeutic window of radiotherapy is defined by the balance between the tumor control probability (TCP) and the normal tissue complication probability (NTCP). The tremendous evolution from bony-landmark two-dimensional radiotherapy over CT-based three-dimensional radiotherapy towards highly-conformal radiotherapy techniques such as intensity ...

[Image guided radiation therapy (IGRT)].

Bulletin du cancer, 2010
Image guided radiation therapy (IGRT) is a major technical innovation of radiotherapy. It allows locating the tumor under the linear accelerator just before the irradiation, by direct visualization (3D mode soft tissue) or indirect visualization (2D mode and radio-opaque markers).

Planar IGRT dose reduction: A practical approach

Practical Radiation Oncology, 2015
To retrospectively estimate the cumulative absorbed dose (at the skin) from kilovoltage planar x-rays received by 90 patients treated on a Varian iX and to determine if that dose could be reduced without sacrificing image quality.To estimate surface dose, measurements were obtained using the "in-air" method by varying the source-to-detector distance ...

CyberKnife®; Imaging-dose evaluation during IGRT-SRSand IGRT-SBRT treatments

2015
Il sistema di radiochirurgia robotica CyberKnife® è utilizzato per trattamenti di radoiochirurgia e radioterapia stereotassica intra ed extracranica guidati dalle immagini (IGRT). I trattamenti di tumori localizzati vengono erogati in singole (radiochirurgia stereotassica SRS[8]) o poche sedute (radioterapia stereotassica SBRT[11]) con un’elevata dose
