Image-Guided Radiation Therapy (IGRT)
For cancers of organs that move with respiration, IGRT—the latest innovation in imaging technology—produce a beam that precisely follows tumor motion and sculpts highly focused radiation around it to protect surrounding healthy tissue from collateral damage. In addition, patient and target positioning can be confirmed just before treatment is delivered. Physicians can see and analyze your tumor, and precisely focus radiation beam to the tumor. This leads to shrinking of radiated area and therefore fewer side effects and ability to return to normal faster than with traditional radiation therapy.

IGRT improves dose sculpting around complex shaped target volumes and minimizes radiation dose to healthy tissues. With IGRT delivery of complex prescription dose gradients close to sensitive tissues is possible.With IGRT “Adoptive treatment planning” has become possible. This is ability to adapt today’s treatment to yesterday’s delivered dose pattern based on tumor response adaptation, as well as target and normal structures shifting adaptation.

It uses sophisticated computer software to analyze a series of image scans to create a detailed, three-dimensional picture of the tumor, or target, and the surrounding tissues. The scans typically are produced by computed tomography (CT scan), magnetic resonance imaging (MRI), or positron emission tomography (PET scan).
