Types of Radiation Treatment


  • Radiation Oncology is the branch of cancer therapy which makes use of high-energy radiation beams to target and destroy the cancer cells and stop their replication inside the body. Radiation therapy can be used alone or as an adjunct therapy along with surgery and chemotherapy for the management of cancer. 


  • 3D Conformal Radiotherapy (3D CRT): An advanced form of cancer treatment where the radiation beams are focussed to match the exact shape of cancer to kill them precisely and avoid harm to surrounding normal healthy cells.

  • Intensity-modulated Radiotherapy (IMRT): An advanced form of radiation oncology that makes use of computer-assisted technology to deliver precise radiation dose at a specific area. The radiation dose intensity can be varied throughout treatment fields.

  • Volumetric Modulated Arc (VMAT): This technology is useful for delivering radiation therapy near sensitive body organs. The key advantages of this technology include high precision, faster treatment and also reduced risk of side-effects.

  • Image-guided Radiation Treatment (IGRT): This technology is used to target tumours that move, such as the lungs, prostrate, liver. Imaging (X-ray) is used along with radiation therapy to improve the precision and accuracy of radiation delivery.

  • Respiratory Active Breath Coordination (ABC): This technology provides non-invasive immobilisation of internal organs that are affected by breathing during treatment. It is useful for minimising the risk of radiation exposure to the heart during the treatment of left breast tumours.

  • Hypo Fractionated Radiation Treatment: It is used as an adjunct therapy in early-stage breast cancer patients undergoing breast conservative surgery. As compared to conventional radiation therapy, this treatment requires fewer therapy sessions.

  • Stereotactic Body / Ablative Radiotherapy (SBRT / SABR): It is used for precise targeting of tumours in the lungs, spine, liver, neck, lymph node or other soft tissues. It makes use of 3D imaging to target high doses of radiation to the tumour in a short overall number of treatment days (usually 1 to 5 days treatment).

  • Stereotactic Radiosurgery (SRS): It involves a single radiation treatment to destroy small tumours in the brain or in the body.

  • Stereotactic Radiotherapy (SRT): It is also employed for precise destruction of tumour cells in the brain and the spinal cord. As compared to SRS, it makes use of a series of radiation therapy over a shorter time.

  • Image-guided Brachytherapy (IGBT): It makes use of advanced imaging technology for accurate, safe and effective placement of radioactive implants (intracavitary/interstitial implant) close to the cancer tissue. It is used alone or in combination with external radiotherapy.

  • Dedicated Big Bore 4D CT Simulator: 4D CT simulator helps in knowing the movement of the tumour due to respiration. By using 4D CT simulator we can exactly know how much the tumour moves during respiration and give adequate margins to encompass the tumour while treating with radiation.
