Image guided radiation therapy (IGRT) is the use of frequent imaging during a course of radiation therapy for the purpose of improving the precision and accuracy of delivery of radiation treatment.
IGRT used scans and X-rays to make sure that patient is in the correct position for radiation treatment.
This is another ADVANCE IN RADIATION THERAPY TECHNOLOGY that improves the chance of killing a cancer while reduces risk damaging normal tissues.
Advantages:
- Accurate delivery of radiation
- Improved definition, localization and monitoring of tumor position, size and shape before and during treatment.
- High targeted radiation dosage to improve tumor control
- Decreased radiation exposure to normal tissues surrounding the tumor
