Image Guided Radiation Therapy (IGRT) in Kanpur | Precision Cancer Care

Why IGRT is Different from Conventional Radiation

Unlike conventional radiation, which assumes a fixed tumor position, IGRT compensates for organ movement and tumor shifts, making treatment more reliable.

• Static Positioning (Conventional Radiation): Does not adapt to organ or tumor movement.
• Dynamic Positioning (IGRT): Uses live imaging to track and correct changes instantly.

The Technology Behind IGRT

IGRT combines cutting-edge imaging and radiation systems to ensure accuracy.

• On-Board Imaging Systems: Built directly into the radiation machine.
• Daily Verification Scans: Confirm tumor location before each session.
• Real-Time Position Adjustments: Patient positioning and beam targeting updated instantly.
• 4D Imaging: Accounts for breathing or digestion-related tumor movement (common in lung or liver cancers).

IGRT offers several unique benefits that make it safer and more effective than older techniques.

• Enhanced Accuracy: Compensates for tumor motion, ensuring millimeter precision.
• Reduced Risk of Missing the Tumor: Daily imaging minimizes “geographic miss.”
• Higher Radiation Doses Possible: Accuracy allows safe delivery of stronger doses, improving tumor control.
• Fewer Side Effects: Healthy tissues are better protected from unnecessary radiation.

How Does IGRT Work?

The IGRT process follows a structured series of steps to ensure maximum accuracy:

• Simulation & Planning: CT/MRI/PET scans map the tumor in detail.
• Daily Imaging Before Treatment: Each session starts with new scans to locate the tumor.
• Position Adjustment: Patient setup and beam angles are adjusted if the tumor has shifted.
• Radiation Delivery: The tumor receives the exact prescribed dose with pinpoint accuracy.
• Ongoing Monitoring: Daily imaging data helps oncologists adapt plans as needed.

Types of Cancers Treated with IGRT

IGRT is especially effective for cancers where tumors move or lie close to critical organs.

• Lung Cancer: Corrects for breathing-related tumor shifts.
• Prostate Cancer: Adjusts for bladder or rectal changes.
• Head & Neck Cancers: Protects salivary glands, spinal cord, and oral cavity.
• Brain Tumors: Enables safe treatment near vital brain structures.
• Abdominal & Pelvic Tumors: Useful for rectal, pancreatic, and gynecologic cancers.
• Liver Tumors: Compensates for digestive and breathing-related organ motion.

IGRT is trusted worldwide for its ability to deliver safer and more precise cancer treatment. Patients benefit from:

• Millimeter-Level Precision: Daily imaging ensures radiation is always on target.
• Adaptability: Adjusts to changes in tumor size, shape, or position.
• Fewer Side Effects: Protects nearby organs such as lungs, bladder, bowel, and heart.
• Higher Treatment Effectiveness: Safe delivery of stronger doses improves tumor control.
• Patient Confidence: Knowing each session is verified gives reassurance and peace of mind.
• Faster Recovery: Most patients can continue daily activities with minimal disruption.

IGRT treatment is carefully structured to maximize both safety and effectiveness.

• Initial Consultation: Patients meet with the oncologist to review diagnosis and treatment suitability.
• Simulation Session: Planning CT scan performed, with immobilization devices for accuracy.
• Daily Treatment Sessions: Each visit begins with scans to confirm tumor position. Sessions last 20–30 minutes.
• Follow-Up & Monitoring: Regular scans and check-ups after completion to track progress.
