SRIOR completes one year of TomoTherapy Radixact

Marking one year since the beginning of the TomoTherapy Radixact X9 system, Sri Ramakrishna Hospital and the Institute of Oncology & Research (SRIOR) continue to strengthen advanced cancer treatment services through sustained clinical outcomes and expanded precision-based care.

The Radixact X9, a radiation therapy platform that integrates imaging and treatment delivery, has significantly enhanced the institute’s ability to deliver personalised, high-precision radiation therapy. With its installation in 2025, the hospital became the first in western Tamil Nadu to operate three advanced radiation treatment machines, including a TomoTherapy unit and two linear accelerators.

The system has enabled real-time tumour tracking, adaptive treatment planning, and reduced radiation exposure to surrounding healthy tissues. The technology has proven particularly effective in treating complex cancers, recurrent tumours, and malignancies requiring high accuracy across multiple sessions.

P. Guhan, Director, Sri Ramakrishna Institute of Oncology & Research, said the first year of Radixact X9’s clinical use has reinforced the institute’s commitment to patient-centric cancer care. He noted that the system’s artificial intelligence–driven planning and adaptive radiation therapy allows oncologists to fine-tune treatment based on daily anatomical and tumour changes, improving outcomes while minimising side effects.

Dr. Guhan added that real-time motion management and adaptive replanning are especially critical for cancers influenced by organ movement, such as lung, head and neck, and abdominal malignancies. The institute has reported consistent clinical improvements, including enhanced precision, better patient comfort, and fewer treatment-related complications. A multidisciplinary oncology team, comprising radiation oncologists, medical physicists, technologists, and nursing staff, continues to work collaboratively to optimise treatment planning and delivery.
