Radiation oncology is a modality of treatment that involves the controlled use of
radiation beams to treat cancer and other symptoms caused by cancer. Radiation therapy
also known as radiotherapy is the term used to describe the actual treatment delivered
by the radiation oncology team.
Radiation therapy can be delivered to treat a wide range of cancers, and may be used
alone or in conjunction with surgery, chemotherapy and other treatments. Radiation
Therapy is usually completely non-invasive, and does not require a patient to be
admitted for the treatment.
Importance of Radiation Oncology
With constant advances in the technologies used for radiation oncology it results in
bringing out successful outcomes for more number of patients, resulting in higher cure
rates, causing no damage to the healthy tissues, shorter treatment time and improved
quality of life. The latest technologies provide three-dimensional images of tumours
that precisely target radiation beams to the cancer, limiting damage to the healthy
tissues, along with advances such as real-time imaging which captures the smallest
involuntary patient movements, such as breathing.
Radiation Oncology at HCG
At HCG we have the most advanced state-of-the-art technologies assisting our specialists
to obtain the best clinical outcomes.
The CyberKnife robotic radiosurgery system is a non-invasive alternative to surgeries
for the treatment of both cancerous and non-cancerous tumors anywhere in the body which
includes Prostate Cancer, Lung Cancer, Brain Cancer, Spine Cancer, Pancreatic Cancer and
Kidney Cancers. CyberKnife uses a movable linear accelerator that is controlled by a
computer. The machine rotates so that it can target the tumor from all possible angles
which makes the treatment more precise. Cyberknife does not affect the surrounding
healthy tissues and also allows the patient to go home in a few hours after the
The Tomotherapy H is a state- of- the- art image guided radiotherapy technique which
combines the benefits of computed tomography (CT scan) and radiotherapy machines. This
helps in imaging the treatment area on a daily basis, pre-treatment, and delivering the
radiotherapy exactly to the area intended. It is possible to do this because the machine
has the unique ability to deliver thousands of beams let’s travelling in a straight line
or in tangents, safely. This cannot be achieved by using any other radiotherapy machine
available in this day and age. It’s the regular CT scanning of the treatment area that
helps the technologists to make on table adjustments, prior to the delivery of
radiation, to correct any shifts that may affect the internal organs.
The TrueBeam is a radiotherapy system which delivers non-invasive radiation to destroy
the tumor cells though out the body and minimises exposure of the radiation to the
surrounding healthy tissue. Its advanced imaging and treatment models allow the doctor
to tailor make treatment plans based on the particular cancer. It synchronises the beam
system to an imaging system that adjusts according to the smallest movement of the
patient including breathing. The ability of the TrueBem to deliver the high dose
radiation at a great speed allows most of the treatment timings to be shortened.
Versa HD is a Versatile, all-in-one system which offers classic radiotherapy to advanced
stereotactic precision. Equipped with sophisticated conformal beam-shaping technology
and High Dose rate mode delivery, Versa HD™ is designed to provide the precision and
speed necessary to deliver advanced stereotactic radiotherapy (SRT) and stereotactic
radiosurgery (SRS), techniques that demand the maximum accuracy in tumor targeting and
protection of critical structures.
The Agility- synergy is a linear accelerator that enables extremely accurate, image
guided adaptive radiotherapy to be delivered safely and in a short period of time. This
makes it possible to treat the cancer at any site in the body with great precision to an
extent that even non-cancerous conditions like Meningioma, Trigeminal Neuralgia and
Acoustic Neuroma can be treated effectively.
Artiste with CT on rails
The Artiste is Asia’s first IGRT with CT-on-rails, making cancer treatment more accurate
with minimal side-effects. This provides a high level of accuracy, with a minimal dose
to the healthy tissue and maximum does close to the target area. This gives the
physicians a broad selection of imaging options and image-based target verification.
Brachytherapy is a type of internal radiation therapy; this therapy allows the
physicians to use a higher dose of radiation to treat a smaller area and in a shorter
time period with external beam of radiation. Brachytherapy is used to treat wide range
of cancers including the Prostate Cancer, Head & Neck Cancer, Cervical Cancer, Skin
Cancer, Breast Cancer, Gall Bladder Cancer, Uterine Cancer, Vaginal Cancer, Lung Cancer,
Rectum Cancer and Eye Cancer.
Hyperthermia is a medical treatment, which involves heating a part of the body to 42°C
and at this temperature the cancer cells can be destroyed with ease through radiation
and anti-cancer drugs. Hyperthermia when combined with radiation or chemotherapy can
treat tumors on the skin, tumors of the Head & Neck region that may have spread to the
