Image-Guided Radiation Therapy
Advanced real-time imaging for unparalleled accuracy during every treatment session.
What is IGRT?
Image-Guided Radiation Therapy (IGRT) uses frequent imaging during a course of radiation therapy to improve the precision and accuracy of treatment delivery. IGRT involves the use of various imaging technologies like CT scans, X-rays, or ultrasound to identify the exact location of the tumor before and during each treatment session. Tumors can shift slightly due to breathing, digestion, or weight changes. IGRT allows physicians to adjust the patient's position and modify the treatment field dynamically, ensuring the radiation is delivered exactly where it's needed.
Benefits of IGRT
- ✓ Real-time tumor tracking during treatment
- ✓ Accounts for organ movement and body changes over the treatment course
- ✓ Increases treatment accuracy significantly
- ✓ Enables reduction in treatment margins, saving healthy cells
- ✓ Better outcomes with fewer side effects
How IGRT Works
Before each treatment session, imaging scans are taken using the linear accelerator's onboard imaging capabilities to verify the exact position of the tumor. These images are compared with the original treatment planning images. If the tumor has shifted, the robotic treatment couch adjusts your position automatically before the radiation is delivered. This ensures maximum precision in every single session.

Frequently Asked Questions
What is the difference between IMRT and IGRT?
IMRT controls the intensity and shape of the radiation beams, while IGRT uses imaging to ensure the beams hit the exact right spot every day. They are often used together for maximum precision.
Does the imaging in IGRT expose me to extra radiation?
The imaging used for IGRT involves a very small, safe amount of radiation. The benefits of hitting the tumor accurately and sparing healthy tissue far outweigh the minimal exposure from the imaging.
Do I need to hold my breath during IGRT?
For certain tumors that move with breathing (like lung or breast cancer), you may be asked to use a technique called Deep Inspiration Breath Hold (DIBH), but the IGRT system tracks this motion automatically.
