Tomotherapy

Precision Radiation Therapy, Delivered from Every Angle. You're in safe hands!

Tomotherapy Technology

Tomotherapy is an advanced radiation treatment that combines a high-precision radiation system with an integrated CT scanner in a single machine. By taking 3D image scans immediately before each session, it allows radiation oncologists to pinpoint the exact size and position of a tumour in real time, ensuring maximum accuracy during every single treatment.

 

This technology is especially effective for treating irregularly shaped or hard-to-reach tumours, as well as cancers located near critical organs. At Manipal Hospitals, Tomotherapy is utilised by our Radiation Oncology team to deliver targeted cancer care that minimises side effects and protects nearby healthy tissue.

How It Works?

A tomotherapy machine combines a rotating radiation source with built-in CT imaging. Before each treatment session, the machine captures a CT scan of the patient's tumour and surrounding anatomy, allowing the care team to verify the tumour's exact position and adjust the treatment plan if needed, even accounting for small changes in body position or tumour size between sessions.

 

During the procedure, the built-in CT scan first verifies tumour alignment. Then, the machine adjusts the intensity and angle of the radiation beams in real time to match the exact shape of the tumour. The procedure is entirely painless, non-invasive, and completed in daily outpatient sessions that typically take 15 to 20 minutes.

Patient Journey

The oncologist reviews the patient’s diagnosis, imaging, and overall health to determine whether tomotherapy is the most suitable radiation therapy option for the patient's specific cancer.

Technology Advantage

Advanced TechnologyConventional Approach
PrecisionDelivers radiation in a continuous 360-degree helical spiral with thousands of narrow beamlets, precisely matching complex tumour shapes while minimising exposure to adjacent healthy tissueDelivers radiation from a limited number of fixed angles, making it harder to conform tightly around irregularly shaped tumours
VisualizationIntegrated low-dose CT imaging before every treatment session confirms exact daily patient positioning and tumour volume changes in real time (IGRT)Relies on periodic 2D portal imaging or external anatomical markers, which may not account for daily internal organ movement
InvasivenessNon-invasive high-precision radiation delivery designed to maximise dose distribution to the target volume while sparing surrounding critical structuresNon-invasive, but broader beam margins carry a higher risk of incidental radiation exposure to healthy surrounding organs
RecoveryOutpatient treatment with zero surgical downtime; enhanced healthy tissue sparing reduces treatment-related toxicities and side effectsOutpatient treatment, but higher scatter radiation to normal tissue can cause increased fatigue and local tissue irritation
Patient ExperienceSeamless ring-gantry design enables treatment of multiple tumour sites or large fields (e.g., total marrow irradiation) in a single continuous sessionRequires multiple couch recalibrations and beam resets when treating complex or widespread target areas, extending session duration
