TomoTherapy H: Personalizing Radiotherapy to Enhance Patient Well-Being Technology and Treatment Center


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 and Volumetric Modulated Arc Therapy (VMAT). 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 tumors present in hard-to-reach sites easy. The built-in 3D CT imaging feature helps specialists confirm the shape and exact position of the tumor 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 the TomoTherapy H Series with HDA configuration.

How Does TomoTherapy H Work?

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

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

CT Imaging and Patient Positioning:Just before the session, a CT scan is performed to confirm the tumor’s position, and the patient is positioned for the radiation therapy accordingly. In a few cases, the tumors 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 tumor.

Radiation Delivery:TomoTherapy facilitates slice-by-slice radiation delivery, and the tumor is targeted from multiple angles. This platform works much like a CT scanner by rotating around the patient, who is positioned on the treatment couch. This linac delivers radiation in a spiral delivery pattern, which facilitates multiple angle dose distribution and treats the tumor more precisely.

Advantages of Radiation Treatment with TomoTherapy H

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

Verifies the location of the tumor before each session and thereby spares more normal tissue and helps reduce side effects.

Helps patients receive treatments that are not possible with conventional linacs.

Facilitates personalized 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, adaptive planning, and seamless radiation therapy.

Helps with radiation treatment-related side effects to some extent.

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 6 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 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 to 4 weeks to recover from radiation fatigue, but in some cases, it can go up to 3 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. It could involve various tests like a PET-CT scan, an MRI, blood tests, or a biopsy.

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