Overview
Treating cancer with precision while protecting healthy tissue
Radiation therapy has advanced far beyond simple beam delivery — today’s approach uses detailed 3D imaging, computer-optimised planning, and daily image guidance to shape radiation dose tightly around the tumour while sparing the organs and tissue around it. Whether IMRT, VMAT, or 3D-CRT is the right technique depends on tumour location, size, and proximity to critical structures, but in every case the plan is built around the same goal: maximum tumour control with minimum side effects.
Treatment begins with a planning CT scan and simulation session to map the exact size, shape, and position of the tumour, followed by careful contouring of the target and nearby organs at risk. A personalised dose plan is then created using advanced software to shape radiation beams precisely around the tumour from multiple angles. Daily image guidance (IGRT) confirms accurate positioning before every session, ensuring the treatment stays on target even as the body shifts slightly day to day.
Because radiation therapy is often combined with surgery, chemotherapy, or hormonal therapy, every case is discussed within a multidisciplinary tumour board — radiation oncology, surgical oncology, medical oncology, and supportive care working together to sequence treatment for the best outcome with the least impact on quality of life.
What We Offer
Radiation Therapy Techniques
A complete range of external beam radiation options, matched to tumour type, location, and treatment goals.
Intensity-Modulated Radiation Therapy (IMRT)
Computer-optimised radiation delivery that varies beam intensity across hundreds of tiny segments, shaping dose precisely around irregular tumour contours while sparing nearby healthy tissue.
Image-Guided Radiation Therapy (IGRT)
Daily imaging performed immediately before treatment to verify tumour position and patient setup, ensuring millimetre-level accuracy throughout the course of therapy.
Volumetric Modulated Arc Therapy (VMAT)
An advanced form of IMRT that delivers radiation in a continuous rotating arc around the patient, shortening treatment time while maintaining high precision.
3D Conformal Radiation Therapy (3D-CRT)
Radiation beams shaped to match the three-dimensional profile of the tumour from multiple directions, concentrating dose on the target while limiting exposure to surrounding tissue.
CT Simulation & Treatment Planning
Detailed imaging and computer-based dose planning performed before treatment begins, forming the blueprint for every subsequent radiation session.
Radiation Treatment Verification & Weekly Review
Ongoing imaging checks and physician review throughout the treatment course to confirm accuracy and adjust the plan if needed.
Our Approach
The Radiation Oncology Advantage
Precise tumour targeting and healthy tissue protection, planned together from the start.
A clear, supported path from first consultation through to long‑term follow‑up.
Image-Guided Accuracy
Daily imaging before each session confirms exact tumour position, keeping treatment on target throughout the entire course.
Personalised Dose Planning
Every treatment plan is individually shaped around the patient's tumour anatomy and nearby organs, built using advanced planning software.
Healthy Tissue Protection
Conformal and intensity-modulated techniques concentrate dose on the tumour while minimising exposure to surrounding organs and tissue.
Multidisciplinary, Whole-Person Care
Radiation oncology, surgical oncology, medical oncology, and supportive care coordinate from diagnosis through recovery.
No. External beam radiation itself is painless — each session feels similar to having an X-ray taken, though some side effects may develop over the course of treatment.
This depends on the type and stage of cancer being treated. Courses can range from a single session to several weeks of daily treatment, and will be outlined clearly in your personalised plan.
Modern techniques like IMRT and IGRT are specifically designed to concentrate dose on the tumour while sparing surrounding healthy tissue and organs as much as possible.
Yes. Radiation is often used before surgery to shrink a tumour, after surgery to eliminate residual cells, or alongside chemotherapy — the sequencing is determined by the multidisciplinary tumour board.
A CT scan is taken in the exact position you’ll be treated in, sometimes with the use of a positioning device or temporary skin markings, to ensure treatment is delivered accurately every session.
