Image Guided Radiation Therapy (IGRT)
Image Guided Radiation Therapy (IGRT) is a radiation technique that combines the principles of external beam (3D conformal or IMRT) with real-time diagnostic images in combination with a course of radiation therapy. Diagnostic scans assist with tracking a tumor whose location is potentially disrupted by irregular movements of critical structures within the body, such as the bladder or lungs. This allows the radiation oncology team to aim the radiation beam more accurately at the cancer while avoiding surrounding healthy tissue. The Trilogy system is equipped with an On-Board Imager™ (OBI) which has the capability of performing cone beam CT scans or kV X-rays for daily localization or tracking of the tumor. Below are common disease sites for which IGRT can be used:
- Prostate
- Breast
- Lung
- Head & Neck
- Brain
- Gynecological
- Gastrointestinal
