IGRT (Image-Guided Radiation Therapy)

IGRT stands for Image-Guided Radiation Therapy. It’s an advanced technique used in radiation oncology to improve the precision and accuracy of radiation treatment for cancer patients.

Image-Guided Radiation Therapy (IGRT) is an advanced technique used in radiation therapy that utilizes imaging technology to improve the precision and accuracy of treatment. By incorporating real-time imaging, IGRT ensures that radiation is delivered precisely to the tumor while minimizing exposure to surrounding healthy tissues.

Here are some key points about IGRT:

1. Precision: IGRT uses imaging technologies (like CT scans, MRIs, or X-rays) to visualize the tumor and surrounding tissues just before and during treatment. This ensures that the radiation is delivered precisely to the target area.
2. Real-Time Adjustments: The images obtained allow for real-time adjustments to the treatment plan if the tumor’s position changes due to patient movement, breathing, or other factors.
3. Enhanced Treatment: By improving targeting, IGRT can minimize damage to surrounding healthy tissues, potentially reducing side effects and improving outcomes.
4. Techniques Used: Common imaging techniques in IGRT include cone-beam CT, fluoroscopy, and ultrasound.
