Image-Guided Radiation Therapy (IGRT)

Precision. Safety. Confidence in Every Treatment.

Cancer treatment has come a long way — and one of the most advanced breakthroughs is Image-Guided Radiation Therapy (IGRT). At the centre of this cutting-edge approach is one clear goal: to deliver radiation with pinpoint accuracy while protecting the surrounding healthy tissues as much as possible.

Under the expert care of Dr. Bharat Dua, IGRT brings together innovation, expertise, and compassion to ensure every patient receives radiation therapy that is not only effective but also safe and comfortable.

What is Image-Guided Radiation Therapy (IGRT)?

Image-Guided Radiation Therapy (IGRT) is a highly precise form of external beam radiation therapy that uses advanced imaging technologies to guide and monitor the delivery of radiation treatment.

Unlike traditional radiation therapy — where doctors rely on static images taken before treatment begins — IGRT uses real-time imaging during each session. This allows oncologists to track even the smallest movements of a tumor or surrounding organs, adjusting radiation beams instantly to maintain pinpoint accuracy.

In simple terms, IGRT ensures that the radiation dose always hits the target, even if the tumor shifts slightly due to breathing, digestion, or natural body movement.

Why is IGRT Important?

Tumors can move. Even small shifts can affect how radiation is delivered — potentially missing part of the tumor or exposing nearby healthy tissues. IGRT helps overcome this challenge by combining precision imaging and adaptive radiation techniques.

This means:

• Greater accuracy in radiation delivery.
   
• Higher confidence that the tumor gets the full, intended dose.
   
• Reduced side effects and protection for surrounding healthy organs.
   
• Improved outcomes and overall treatment success.
   

For patients, IGRT brings peace of mind — knowing that every treatment session is personalized and guided by real-time data.

How IGRT Works: Step-by-Step

Here’s how a typical IGRT treatment works under the expert supervision of Dr. Bharat Dua:

1. Preparation and Planning
    Before treatment begins, detailed 3D images of the tumor and nearby organs are captured using CT, MRI, or PET scans. These images help design a customized radiation plan that targets the tumor’s exact shape and size.
    
2. Daily Imaging Before Treatment
    Before each radiation session, imaging tools such as cone-beam CT scans or X-rays are used to check the tumor’s current position. This ensures that any changes — even minor ones — are detected before radiation starts.
    
3. Real-Time Adjustments
    If the tumor has shifted due to breathing or internal movement, the system automatically adjusts the patient’s position or the radiation beam’s angle.
    
4. Precise Radiation Delivery
    Once alignment is confirmed, radiation is delivered with exceptional precision, ensuring the tumor receives the intended dose while minimizing exposure to nearby healthy tissues.
    

This combination of imaging and real-time corrections makes IGRT one of the most accurate forms of radiation therapy available today.

Benefits of Image-Guided Radiation Therapy (IGRT)

When performed by a skilled radiation oncologist like Dr. Bharat Dua, IGRT offers multiple benefits that significantly enhance treatment quality and patient comfort:

• Unmatched Accuracy – Radiation beams are guided directly to the tumor, reducing the chance of missing the target.
   
• Fewer Side Effects – Because radiation exposure to healthy tissues is minimized, patients experience fewer side effects and faster recovery.
   
• Higher Treatment Effectiveness – The precision allows doctors to safely deliver higher doses, improving treatment outcomes.
   
• Adaptability – Tumors can change in size or position over time, and IGRT allows treatment plans to adapt accordingly.
   
• Enhanced Safety – Real-time imaging ensures every treatment session is as safe and effective as possible.
   
• Improved Patient Confidence – Patients feel reassured knowing that their treatment is guided by the latest imaging technology and expert care.
   

Conditions Treated with IGRT

IGRT is a versatile technique used to treat a wide range of cancers, especially those located near vital organs or that tend to move with normal body functions. These may include:

• Prostate Cancer
   
• Lung Cancer
   
• Head and Neck Cancers
   
• Brain Tumors
   
• Pancreatic Cancer
   
• Liver Cancer
   
• Gynecologic Cancers
   
• Bladder and Rectal Cancers
   

Each of these cancers requires exceptional precision — and that’s exactly what IGRT provides.
