IGRT Radiotherapy in Lucknow | I D Cancer Centre
Ultra-Precise, Safe & Modern Cancer Radiotherapy at I D Cancer Centre, Lucknow
IGRT, or Image-Guided Radiotherapy, is one of the most advanced technologies used in modern radiation oncology. It uses real-time imaging before and during treatment to ensure that radiation is delivered exactly to the tumour, even if it shifts slightly due to breathing, movement, or natural changes inside the body.
What Is IGRT?
IGRT is a technique in which special imaging (X-ray, CT, cone-beam CT) is used before each radiotherapy session to:
Verify tumour position
Adjust patient setup
Ensure accurate radiation delivery
Protect surrounding normal tissues

In simple words:
IGRT makes radiotherapy safer and more precise by checking tumour position daily before giving radiation.

Why IGRT Is Needed
Tumours and internal organs can shift due to:
Breathing
Eating or digestion
Bladder/bowel filling
Weight loss during treatment
Natural body movement
Without IGRT, even small shifts can cause radiation to miss part of the tumour or affect nearby healthy organs.
IGRT eliminates this risk by ensuring perfect alignment every day.

How IGRT Works
Step 1: Daily Imaging
Before each treatment, the machine takes detailed images (X-ray or cone-beam CT).

Step 2: Tumour Verification
The doctor and radiation therapist compare the images with the original treatment plan.

Step 4: Radiation Delivery
Once perfect positioning is confirmed, treatment begins.
This ensures that radiation hits the tumour with maximum precision and reduces side effects.
