Radiation Oncology
Overview
In year 1977 the department started in full-swing since the inception. This one of the modalities available to treat the solid tumours, where 70% to 80% of the patients require radiotherapy either alone or in combination with surgery and / or chemotherapy, with the aim to either cure those tumours or ease the distressing symptoms in terminally ill individuals. In early stages of cancer (Stage I & II) radiotherapy can cure more than 80% of the patients.
Bhabhatron II cobalt-60
Bhabhatron is an isocentric, external beam radiation therapy machine designed for the treatment of cancer patients. It uses radioactive cobalt-60 isotope as the source of radiation. It is a computer-controlled system to deliver planned amount of radiation exposure to the designated target safely and accurately.

Linear Accelerator VERSA HD-
The unit is a recent addition of sophisticated linear accelerator technology at CHRI. The Versa HD utilizes the Agility 160 leaf multi-leaf collimating system, which allows for precision shaping of the beam to the treatment area. The Versa HD is also capable of delivering Volumetric Modulated Arc Therapy (VMAT) & Intensity-modulated radiation therapy (IMRT), which provides our patients with faster treatment deliveries and improves the overall treatment experience. This unit allows for very accurate setup of the patient on the machine with the ability to make small adjustments to the positions of patients to exactly align them with the radiation beams. Through its high-end features, such as advanced beam-shaping, superior imaging and capability to deliver high-dose-rate radiation, Versa HD is especially helpful in the management of tumours located in critical areas.
Advantages of Linear Accelerator Versa HD
- It helps specialists treat challenging cancers with submillimetre accuracy.
- Through dual registration of target(s) and critical structures, it helps radiation oncologists protect the critical structures close to the tumour while also achieving positive outcomes.
- It can treat small and multiple targets in complex structures, namely lungs.
- Through high-dose-rate radiation delivery, this helps in reducing the overall treatment duration.
- Radiation therapy with Versa HD is a non-invasive procedure with fewer treatment-related complications, and in most cases, patients see faster recovery.
V MAT
Volumetric modulated arc therapy (VMAT) is an advanced radiotherapy technique that uses arcs of radiation, rather than individual beams used in other types of radiotherapy. As the linear accelerator machine moves, it automatically changes the beam shape and treatment dose. This makes the treatment much more targeted and accurate than single beam-based radiotherapy.

IMRT
Intensity-modulated radiation therapy (IMRT), is an advanced type of radiation therapy. Radiation therapy uses powerful energy beams to kill cancer cells. The energy can come from X-rays, protons or other sources. With IMRT, the beams of radiation are carefully customized. The beams are shaped to match the shape of the cancer. The beams can move through an arc while they deliver the radiation. The intensity of each beam can be varied. The result is a precisely controlled radiation treatment. IMRT delivers the correct radiation dose as safely and efficiently as possible. IMRT can be used to treat cancers and tumours that aren’t cancerous, which are called benign tumours. It can treat cancers and tumours anywhere in the body. The goal of treatment is to target the radiation so that nearby healthy tissue isn’t hurt.
3D-CRT
A procedure that uses a computer to create a 3-dimensional picture of the tumour. This allows doctors to give the highest possible dose of radiation to the tumour, while sparing the normal tissue as much as possible. Also called 3-dimensional conformal radiation therapy and 3-dimensional radiation therapy.
The consultant assesses patient’s condition and precise diagnosis to decide if this treatment is right. CHRI’s multidisciplinary & compassionate team of specialists, including oncologists, radiographers, physicists, and nursing staff manages patient’s treatment.
