Utilize technology

  • Cyberknife VSI

    Cyberknife system is used for performing robotic radiosurgery. It is a robotic radiosurgery system which helps in handling the non-threatening tumours, malignant tumours, and other medical conditions. With the support of advanced technology, Cyberknife – available at Medanta – works as a detector to visualise the tumour, measure it with accuracy which helps the doctors to diagnose the problem and take necessary actions. A robotic arm is used in this technology to engage the radiation rays with any part of the body. A Lightweight Linear Accelerator, commonly abbreviated as LINAC, is involved with a Robotic arm, ensuring view from different angles.

  • Linear Accelerators

    Infinity and Synergy-S, linear accelerators at Medanta Cancer Institute are capable of treating all body cancers including brain, head and neck, breast, sarcomas, cervix, uterus cancers, prostate, kidney, oesophagus, stomach, gall bladder, pancreas, liver, colon, rectum and anal canal.

  • Integrated Brachytherapy Unit

    A cutting edge technology in brachytherapy. The tumours that have a higher control with brachytherapy are Cancer Cervix, Endometrial Cancer, Oesophagus Cancer, Lung Cancer and Cholangiocarcinoma. The advanced dosimetry and standardized processes at Medanta Cancer Institute ensure that patients do not miss their treatment if one of the machines is under maintenance or repair. In case you have a breakdown or delay on your treatment units, we shall be ready to provide treatment to you patients to maintain continuity of care.

  • Tomotherapy HD

    It is the world's only integrated image-guided-intensity-modulated (IG-IMRT) delivery system. It permits helical radiation delivery that can treat tumours like medulloblastomas, acute lymphatic leukaemias (Total Body Radiation) and bilateral breast cancer in a very short time. The dose to heart, lungs, and kidneys can be reduced to very low levels resulting in the mitigation of acute and delayed radiation effects. Tomotherapy – is especially recommended for:

    • Megna-field radiotherapy in the form of total body, half body and total nodal irradiation
    • Medulloblastoma-childhood brain tumour
    • Methelioma-cancer of lung surface
    • Total Body Irradiation (TBI) for bone Marrow transplantMultiple metastases (Prostate, Breast cancer)
    • Multiple metastases (Prostate, Breast cancer)

  • Volumetric Arc Therapy

    VMAT delivers a precisely sculpted 3D dose distribution with a 360 degree rotation of the gantry in a single or multi arc treatment. It also modulates the radition for higher conformity while rotating the machine around the patient. It allows treatment delivery speed that is 4 times faster than traditional IMRT. At Medanta, it is used to treat head and neck, prostate and lung cancers keeping in mind patient’s comfort.


    A dedicated system for non-invasive stereotactic radiosurgery and stereotactic radiotherapy (SRS and SRT), represents cutting-edge technology for treatments of the highest precision. Its X-ray-based localisation technology allows our physicians to localise tumours with sub-millimeter accuracy and to position patients automatically and with the highest degree of precision.

  • IGRT

    Image Guided Radio Therapy is a type of therapy which can shape the radiotherapy beams around the area of cancer. Our doctors at Medanta have used this technology treat the cancers precisely and accurately. This reduces the side-effects of the treatment.

  • PET Scan

    A positron emission tomography (PET) is a diagnostic test that allows the doctor to check for diseases in your body. The scan uses a special dye that has radioactive tracers. These tracers are injected into a vein in your arm. Your organs and tissues then absorb the tracer. When highlighted under a PET scanner, the tracers help your doctor to see how well your organs and tissues are working. The PET scan can measure blood flow, oxygen use, glucose metabolism (how your body uses sugar), and much more.

  • Radiation Therapy for Bladder Cancer

    Bladder cancer begins when cells in urinary bladder start to grow uncontrollably. The type of radiation most often used to treat bladder cancer, known as external beam radiation therapy, focuses radiation from a source outside of the body on cancer. Before your treatments start, your radiation team will take careful measurements to find the correct angles for aiming the radiation beams and the proper dose of radiation. This planning session, called simulation, usually includes getting imaging tests such as CT or MRI scans.

  • Radiation Therapy in Head and Neck Cancer

    A radiation therapy regimen at Medanta usually consists of a specific number of treatments given over a set period of time. Before beginning radiation therapy for any type of head and neck cancer, patients are examined by an oncologic dentist or oral-oncologist. After the therapy, patients begin speech and swallowing therapy to prevent long-term problems with speaking and eating.

  • Radiation Therapy for Brain Tumour

    Our team of neurologist, radiation oncologist, medical oncologist and endocrinologist are at your disposal to treat these sensitive tumours in the brain. The radiation team predetermines the correct angles of aiming the radiation beams and the proper dose of radiation. The technology used at Medanta to treat brain tumours include Cyberknife VSI, Integrated Brachytherapy Unit, Volumetric Arc therapy, SBRT/SRS and IGRT.

  • Radiation Therapy for Thoracic Cancer

    Radiation plays an important role in the treatment of thoracic tumours. During the last 10 years, there have been several major advances in thoracic RT including the incorporation of concurrent chemotherapy and the application of conformal radiation delivery techniques (eg, stereotactic RT, three-dimensional conformal RT, and intensity-modulated RT) that allow radiation dose escalation. Radiation as a local measure remains the definitive treatment of medically inoperable disease in NSCLC and part of a multimodality regimen for locally advanced NSCLC, limited stage SCLC, oesophagal cancer, thymoma, and mesothelioma.

  • Radiation Therapy in Breast Cancer

    1. Breast cancer occurs almost entirely in women, but men can get breast cancer, too. Not all women with breast cancer need radiation therapy, but it may be used in several situations such as:
    • After breast-conserving surgery (BCS), to help lower the chance that cancer will come back in the breast or nearby lymph nodes
    • After a mastectomy, especially if the cancer was larger than 5 cm (about 2 inches), or if cancer is found in the lymph nodes
    • If cancer has spread to other parts of the body, such as the bones or brain

    At Medanta, our breast services team uses Hypofractionated radiation therapy, Intraoperative radiation therapy and 3D – conformal radiotherapy to provide you with long-term and stable results.

  • Radiation Therapy in Abdominal Cancer

    Organs of the abdomen include the stomach, small intestine, colon, liver, gallbladder, spleen and pancreas. Before your treatment starts, the radiation team will take careful measurements to determine the correct angles for aiming the radiation beams and the proper dose of radiation. Radiation therapy can be used to slow the growth and ease the symptoms of advance abdominal cancer.

  • Radiation Therapy for Pelvic Cancer

    The pelvis is either the lower part of the trunk of the human body between the abdomen and the thighs. Radiation therapy to the pelvis can be used to slow the growth and ease the symptoms of advanced pelvic cancer.

  • Tomotherapy

    Tomotherapy combines an advanced form of intensity modulated radiation therapy (IMRT) with the accuracy of computed tomography (CT) scanning technology, all in one machine. Using in-built CT scanning to confirm the shape and position of the tumour before each treatment, Tomotherapy reduces radiation exposure to healthy tissues and organs.

  • Craniospinal Irradiation

    Craniospinal irradiation is used for patients who have or are at risk for, disseminated disease throughout the CNS that is not sufficiently responsive to chemotherapy (typically methotrexate). This includes:

    • Embryonal CNS malignancies (medulloblastoma, primitive neuroectodermal tumour, atypical teratoid/rhabdoid tumour)
    • Intracranial germ cell tumour with evidence of distant CNS metastases
    • Ependymoma with evidence of distant CNS metastases or CSF involvement

    Craniospinal Irradiation is also used for paediatric patients because of its simplicity.

Why choose Medanta?

Medanta has formed the Disease Management Group (DMG) at the Cancer Institute. In this approach for each type of cancer, a specific multidisciplinary group of doctors that includes medical oncologists, radiation oncologists, surgical oncologists, pathologists, radiologists and physiologists meet in a tumour board setting to discuss cases and debate the best possible course of treatment.
