ETHOS Adaptive Radiotherapy with SGRT: New Era for Cancer Treatment

English हिन्दी

What is Adaptive Radiotherapy?

Adaptive radiotherapy is an advanced technique used in radiation therapy for cancer treatments. It overcomes the challenges of traditional radiation therapy like, changes in a patient’s anatomy or tumor during the course of treatment, deviations in planned delivered dose due to patient setup deviations or machine delivery deviations, etc.

Adaptive radiotherapy modifies/ adapts to these uncontrolled variables, and delivers most efficient radiation treatment. This approach allows for real-time adjustments to treatment plans, optimizing the radiation dose to target the tumor cells. Adaptive radiotherapy also minimizes damage to the healthy surrounding tissues. Imaging technologies like CT scans or MRI are used to monitor changes and make necessary adaptations.

Why Adaptive radiotherapy?

In traditional radiation therapy, high doses of radiation are administered multiple times, over several weeks, to reduce tumor size, destroy tumor cells, and relieve symptoms. As a result-

• the size, shape or location of the tumor continuously changes
• the size, shape or location of nearby organs continuously changes
• continuous weight loss happens

Thus, adjustments to the dosage of radiation becomes important during the course of treatment. Adaptive radiotherapy allows continuous treatment adjustments, adapting to these changes, delivering the most accurate radiation dosage possible.

How is Artificial Intelligence Radiotherapy used?

Artificial Intelligence based Adaptive Radiotherapy enhances cancer treatment planning, radiation dose delivery, and dosage monitoring. 

Let’s see how-

Treatment Planning: Analyze medical images, like CT scans, MRI, thus assisting radiation oncologists in designing precise treatment plans. It helps to identify tumor boundaries and calculate appropriate radiation doses to target the tumor along with sparing healthy surrounding tissues.

Dose Prediction:  Adaptive Radiotherapy predicts radiation doses interactions with different tissues, thus creates therapeutic treatment plans with minimal side effects.

Real-time image data analysis- Adjust the radiation delivery based on any changes in the patient’s anatomy or tumor position, during treatment.

Treatment Response Monitoring: Tumor responses are analyzed in medical images over time, which helps oncologists modify treatment plans if needed.

Quality Assurance: Accuracy of radiation delivery systems, the prescribed dose matches the actual dose being delivered, is ensured.

Refined treatment strategies based on Data Analysis:  Treatment result patterns are identified, based on data analysis of medical records, that can aid in refining treatment strategies and predicting patient responses.

Revolutionising Radiotherapy for Personalized Cancer Treatment: India’s 1st ETHOS Adaptive Radiotherapy with Surface Guided Radiotherapy

With the Ethos Adaptive Radiotherapy platform, doctors can now efficiently plan & administer the radiation treatment in just 15 minutes.

VARIAN Ethos radiation therapy system is a novel Artificial Intelligence-based treatment platform that offers high-resolution CT images, helping in localization of the tumor before the treatment. It can create a new treatment plan using its artificial intelligence during treatment – “Adaptive Planning” – and thus helps physicians to save on time.

VARIAN Ethos Adaptive Radiation Therapy system has a cutting-edge solution that revolutionizes cancer treatment like never before.  VARIAN Ethos has features like:

• Adaptive Intelligence based Precision Radiotherapy

Ethos Radiation Therapy System uses inbuilt Artificial Intelligence (AI) algorithms- and Machine Learning (ML)-based mode of operation.

• Highly personalized cancer care

VARIAN ETHOS equipment has a wide treatment bore and a treatment couch that reduces claustrophobia of patients.

• Customized treatment, every patient, everyday

CBCT and Artificial Intelligence ensure that location of tumor in a patient’s body is accurately mapped and targeted during each therapy, in each patient.

•  Enhanced tumor control and reduced side effects

ETHOS adapts to changes in the tumor shape, position, and size during treatment. By accurately tracking and adjusting the treatment beam in real-time, ETHOS maximizes the radiation dose to the tumor while minimizing damage to surrounding healthy tissues.

• Integrated tumor tracking

The changes in anatomy of the patient and the tumor are visualized on a daily basis. The doctors are able to use the patient’s previous imaging such as PET scan, MRI, CT scan to track the tumor daily. This improves the visibility of the tumor, and the ability to track it accurately.

• Faster treatment, better outcomes

Ethos does real time optimizations in precisely targeting the tumor and completing each session in much less time. ETHOS is more than 3 times faster than conventional linear accelerators- reducing patient time, enhancing patient comfort, ensuring less tissue variation during treatment, improving treatment outcomes.

• Enhanced Safety

The Automated treatment planning algorithms makes it error free, rigid safety protocols during radiotherapy sessions ensures safety.

• Increased Precision and Accuracy

ETHOS has state-of-the-art imaging and motion management capabilities. The radiation beam is precisely targeted to the tumor, even when the tumor moves due to the patient’s breathing or motion of the organs. This ensures a high level of precision, allowing the treatment doses to be safely delivered to the tumor.

• Improved Patient Experience and Quality of Life

Superior treatment experience with minimal disruptions to their daily lives, patients experience fewer side effects, leading to improved quality of life during and after treatment, reduced treatment times enable patients to spend less time in the treatment room thus recovery time increases.

Thus, introduction of VARIAN ETHOS Adaptive Radiotherapy in India has significantly advanced cancer care, offering patients access to the state-of-the-art radiotherapy techniques that can improve treatment outcomes. It provides a personalised cancer treatment through adaptive radiotherapy. This ultimately enhances the overall patient experience and quality of life.

When you choose ETHOS, you choose to embrace the future of cancer care. ETHOS tailors the treatments to your individual needs, maximising your chances of a successful outcome.  Cancer treatment with ETHOS improves your overall quality of life.
