  • Introduction

What is IMRT?

Intensity-Modulated Radiation Therapy (IMRT) is an advanced radiation therapy technique that allows precise control of radiation intensity to match the exact shape of the tumour.
Using computer-controlled linear accelerators, IMRT delivers radiation with high precision — reducing damage to nearby healthy tissue and improving treatment outcomes. At Dr. K K Naik’s Oncology Centre, IMRT is a key tool in our personalised approach to cancer care.
  • How It Works

Shaping radiation around the tumour

IMRT divides each beam into thousands of small beamlets, each with adjustable intensity — combining angles and intensities into a dose distribution that hugs the tumour and avoids critical organs.

Multiple beam angles

Radiation is delivered from many directions, converging on the tumour for maximum dose.

Modulated radiation intensity

Beam intensity varies across each angle to conform precisely to the tumour shape.

Precise tumor targeting

Healthy organs near the tumour receive significantly lower doses, reducing side effects.

  • Benefits

Precision that translates into better outcomes

Every session combines real-time imaging with computer-guided beam adjustments — keeping treatment accurate, even as the body moves naturally.

Reduced Side Effects

Lower radiation dose to surrounding healthy tissues and critical organs.

Higher Precision

Dose conforms tightly to the tumour, even around complex anatomy.

Better Outcomes

Higher tumour control rates and improved quality of life during therapy.

  • Conditions Treated

Cancers we treat with IMRT

IMRT is effective across a wide range of solid tumours where precision is critical and surrounding tissues are sensitive.
Head and Neck Cancer
Brain tumors
Breast cancer
