Radiation Oncology Home About Us Our Hospital Our Technology Radiation Oncology Overview The Radiation Oncology Department at Sir H.N. Reliance Foundation Hospital use a variety of equipment and technologies to deliver precise and effective cancer treatment using high-energy radiation. Our advanced linear accelerators, including the Varian Ethos system, enable highly targeted radiation therapy that maximizes tumor control while minimizing exposure to surrounding healthy tissue.Supported by sophisticated treatment planning software and imaging guidance systems, our expert radiation oncologists design and deliver personalized radiation doses with exceptional accuracy and safety. This technology-driven approach ensures superior treatment outcomes with reduced side effects, offering an excellent option for patients who cannot undergo surgery or prefer non-surgical cancer management. Ethos Linear Accelerator Varian TrueBeam Radiosurgery Linear Accelerator with SGRT The Ethos linear accelerator is a simple yet powerful tool in radiation oncology designed to deliver highly personalised cancer care to each patient every day. It allows radiation oncologists to assess the changes in patient anatomy with high diagnostic precision and adjust the treatment plan in real time. This revolutionary therapy transforms online adaptive therapy from being complex and time-consuming to an accessible option for patients with cancer.Ethos offers personalised treatment plans as it considers the unique anatomy of each patient and tumour feature changes over time. Ethos—coupled with superior imaging modalities such as on-board cone-beam computed tomography (CBCT)—permits real-time imaging during therapy. The Ethos system ensures precise tumour targeting and minimises radiation exposure to the adjacent healthy tissues by virtue of its flexibility in terms of adapting and tweaking the treatment plan across the therapy timeline. By reconstructing the delivered dose based on daily anatomical changes, it provides oncologists with the ability to fine-tune treatments in real time, delivering highly personalised cancer care. The TrueBeam radiotherapy system provides high-precision treatment options for a variety of patient needs. Our centre is equipped with the most advanced TrueBeam STx Radiosurgery Linear Accelerator along with a state-of-the-art radiotherapy treatment planning system Eclipse.In addition to SGRT, Radiation Oncology Department of the Sir H.N. Reliance Foundation Hospital hosts diverse radiotherapy modalities:Image-Guided Radiotherapy (IGRT)Volumetric-Modulated Arc Therapy (VMAT)Intensity-Modulated Radiotherapy (IMRT)Three-Dimensional Conformal Radiotherapy (3DCRT)Stereotactic Body Radiotherapy (SBRT)Stereotactic Radiosurgery (SRS)
