The Department of Radiation Oncology at Army Hospital Research and Referral (AHRR), New Delhi, has commissioned a Ring Gantry-based Linear Accelerator, significantly upgrading cancer treatment capabilities for serving military personnel, veterans, and their dependents, according to an official statement issued on Monday, 25 May. The Ministry of Defence said the new system is expected to substantially enhance in-house radiotherapy capacity at the hospital.

What the New Equipment Offers

The Ring Gantry-based Linear Accelerator is capable of delivering a range of advanced radiotherapy techniques, including Volumetric Modulated Arc Therapy (VMAT), Intensity-Modulated Radiation Therapy (IMRT), Image-Guided Radiation Therapy (IGRT), Stereotactic Body Radiation Therapy (SBRT), and Stereotactic Radiosurgery (SRS). These modalities allow clinicians to deliver highly precise doses of radiation directly to tumour sites while minimising exposure to surrounding healthy tissue — a critical factor in improving patient outcomes and reducing treatment side effects.

Replacing Outdated Infrastructure

According to the Ministry of Defence statement, the newly inducted equipment represents a substantial upgrade over the previous Linear Accelerator used within the Armed Forces Medical Services (AFMS), which has since been decommissioned. The induction is described as a key step in the broader modernisation of oncology services across AFMS. Officials noted that other oncology centres under AFMS are also being upgraded in a phased manner, signalling a sustained institutional push to bring military healthcare in line with contemporary standards.

AHRR's Growing Record of Medical Firsts

The commissioning adds to a growing list of medical milestones at AHRR. In 2025, the hospital's Ophthalmology Department made headlines for performing India's first-ever 3D Flex Aqueous Angiography with iStent — a procedure that combined advanced intraoperative imaging with minimally invasive glaucoma surgery, setting a new benchmark in glaucoma care. In August 2025, AHRR became the first government institution in India and the second in South Asia to perform Robotic Custom Laser Cataract Surgery using the ALLY Adaptive Cataract Treatment System, marking its entry into femtosecond laser-assisted, computer-guided eye surgery.

Why This Matters for Military Healthcare

AHRR serves a high patient load comprising active-duty service members, ex-servicemen, and their families — a population that has historically had limited access to cutting-edge oncology care within the military healthcare system. The addition of a Ring Gantry Linear Accelerator brings the hospital's radiation oncology capabilities closer to those available at leading civilian cancer centres. This comes amid a wider national conversation about improving specialised healthcare access for armed forces personnel, and the upgrade is likely to reduce referrals to external facilities, easing both cost and logistical burden on patients.
