TomoTherapy H

The built-in 3D CT imaging feature helps specialists confirm the shape and exact position of the tumour before each session and deliver the radiation beams precisely. Through the image guidance feature, TomoTherapy H reduces radiation exposure to surrounding healthy tissues.

TomoTherapy H – New-age Radiation Therapy Platform

TomoTherapy H is the new-age radiation therapy platform that combines Intensity-modulated Radiation Therapy (IMRT) with the accuracy of Computed Tomography (CT) image guiding technology. TomoTherapy H is designed to treat the entire spectrum of radiation therapy patients with enhanced speed, superior precision and augmented ease-of-use.

TomoTherapy H is the most unique radiation delivery platform that supports full-spectrum radiation therapy with multiple advantages, such as superior performance, unmatched dose distributions and enhanced radiation delivery speed.

TomoTherapy H is designed in such a way that it makes treating tumours present in hard-to-reach sites easy.

The built-in 3D CT imaging feature helps specialists confirm the shape and exact position of the tumour before each session and deliver the radiation beams precisely. Through the image guidance feature, TomoTherapy H reduces radiation exposure to surrounding healthy tissues and thereby brings down the risk of treatment-related side effects.

TomoTherapy H assists in the management of cancers of the breast, lung, head and neck, brain and prostate.

HCG Cancer Centre is the first hospital in India to install TomoTherapy H Series with HDA configuration.

How Does TomoTherapy H Work?

TomoTherapy integrates imaging, planning, positioning of the patient and radiation delivery all in one platform. This helps in reducing the overall treatment duration and leads to better treatment response and recovery.

Treatment Planning: Firstly, 3D images of the target area are captured in order to clearly define the contours of the tumour. Based on the data from the imaging, the intensity of the radiation beams, the position and the shape of the beams are calibrated.

CT Imaging and Patient Positioning: Just before the session, a CT scan is performed to confirm the tumour’s position, and the patient is positioned for the radiation therapy accordingly. In a few cases, the tumours change shape or slightly shift their position, and a CT scan right before every session helps specialists make sure that the radiation is precisely delivered to the tumour.

Radiation Delivery: TomoTherapy facilitates slice-by-slice radiation delivery and this helps in ensuring that the tumour is targeted from every angle. This platform works much like a CT scanner by rotating around the patient who is positioned on the treatment couch. This linac (linear accelerator) delivers radiation in a spiral delivery pattern, which facilitates multiple angle dose distribution and treats the tumour more precisely.

Advantages of TomoTherapy H

TomoTherapy H comes with numerous advantages for both patients and specialists:

  • Verifies the location of the tumour before each session and thereby spares more normal tissue and helps reduce side effects
  • Helps patients receive treatments that are not possible on conventional linacs
  • Facilitates personalised and effective treatment planning for each case
  • Facilitates better planning and efficient delivery of highly sculpted dose distributions
  • Provides daily CT image guidance for precise patient positioning, margin reduction and adaptive planning and facilitates seamless radiation therapy
  • Reduces the risk of radiation treatment-related side effects

Frequently Asked Questions

The treatment duration could be anywhere from 10 to 20 minutes.

Potential side effects associated with TomoTherapy H are fatigue, skin irritation and nausea. Most of the side effects are temporary and wear off over time.

However, if any side effects last longer than six weeks, you should get in touch with your treating doctor.

You may feel tired after the treatment. You may also experience skin irritation. Since it is a non-invasive procedure that takes less time, you can go home right after the procedure.

You may require sufficient rest, which will help your body to prepare itself for the next session.

This depends on the type of cancer, its stage and the overall condition of the patient. Most patients take 3 – 4 weeks to recover from radiation fatigue; but in some cases, it can go up to three months too.

Our doctors will be constantly monitoring your response to the treatment administered. Treatment monitoring helps in assessing if the administered treatment is working as it should be. It could involve various tests like PET-CT scan, MRI, blood tests or biopsy.

Based on the results of these tests, the doctor may continue or alter the treatment plan for better outcomes.
