India’s first ETHOS Adaptive Radiotherapy with Surface Guided Radiotherapy: Revolutionizing Radiotherapy for Personalized Cancer Treatment

Welcome to a new era of cancer treatment at Sir H N Reliance Foundation Hospital with the ground breaking ETHOS Linear Accelerator in combination with Surface Guided Radiotherapy. Adaptive Intelligence based Precision Radiotherapy is the future of radiation therapy, and with ETHOS, we are at the forefront of this revolutionary technology.

  • Customised treatment, every patient, everyday

    ETHOS enables a patient-centric approach by providing personalized treatment plans based on each person's unique anatomy and changes in the tumour over time. With the help of advanced imaging techniques, such as onboard cone-beam computed tomography (CBCT), ETHOS allows for real-time imaging during treatment sessions. This ability to adapt and adjust the treatment plan throughout the course of therapy ensures precise targeting of the tumour and minimizes radiation exposure to healthy tissues.

    Enhanced tumour control and reduced side effects

    ETHOS adapts to changes in the tumour shape, position, and size during treatment. By accurately tracking and adjusting the treatment beam in real-time, ETHOS maximizes the radiation dose to the tumour while minimizing damage to surrounding healthy tissues. This ensures optimal treatment, improved outcomes, and reduced side effects.

    Faster treatment, better outcomes:

    ETHOS is more than 3 times faster than conventional linear accelerators. Hence, the patient’s time on the machine reduces, making the process more comfortable. Also, faster treatment ensures less variation in the tissues while treatment is being delivered, and this improves the treatment outcomes.

    Integrated tumour tracking

    The doctors are able to use patient’s previous imaging such as PET scan, MRI, CT scan to track the tumour daily. This is a significant change compared to other linear accelerators, where only CT scan taken during radiotherapy planning is available for comparison. This significantly improves the visibility of the tumour, and the ability to track it accurately.

    Enhanced Safety

    ETHOS has an intuitive user interface and automated treatment planning algorithms that makes the whole process completely automated and free from errors. The rigid safety protocols during radiotherapy planning and treatment ensures that there is no room for error and the treatment is delivered precisely and safely.

    Increased Precision and Accuracy

    Compared to non-adaptive treatment methods, ETHOS has state-of-the-art imaging and motion management capabilities and can account for daily anatomical variations and intra-fraction motion, ensuring that the radiation beam is precisely targeted to the tumour, even when the tumour moves due to patient’s breathing or motion of the organs. This level of precision allows for higher treatment doses to be safely delivered to the tumour, while minimizing the risk to surrounding healthy tissues.

    Improved Patient Experience and Quality of Life

    Adaptive radiotherapy using ETHOS offers patients a superior treatment experience with minimal disruptions to their daily lives. By precisely targeting the tumour and minimizing radiation exposure to healthy tissues, patients experience fewer side effects, leading to improved quality of life during and after treatment. The streamlined workflow and reduced treatment times enable patients to spend less time in the treatment room, allowing them to focus on their recovery and spend more time with their loved ones.

    Unique combination of SGRT and ETHOS

    We at Sir H N Reliance Foundation Hospital are the pioneers of Surface guided radiotherapy (SGRT) in India. This is a unique technology which helps us to continuously track the patient’s body to ensure precise treatment, which significantly enhances the accuracy of the ETHOS Adaptive Radiotherapy. Because of this technology, we do not have to put any tattoos or permanent markings on the patient’s body.

    Join the Revolution with ETHOS

    ETHOS at Sir H N Reliance Foundation, Mumbai is transforming cancer treatment by bringing Adaptive Intelligence based Precision Radiotherapy to the forefront. By choosing ETHOS, you are embracing the future of cancer care, where treatments are tailored to your individual needs, maximizing your chances of a successful outcome and improving your overall quality of life.
