Stereotactic Radiotherapy

Stereotactic radiosurgery is the use of multiple small beams to deliver very high ablative doses of radiation, from different angles and planes, shaped to the size of the tumour. It is most often used on small, well-defined tumours. Three-dimensional imaging is used to determine the exact coordinates of the tumor to localize it. Contrary to its name, it is a non-surgical radiation therapy that ca be used as an alternative to invasive surgery.

Its biggest benefits over conventional therapy are:

• It can treat very small tumors or those located in hard-to-reach places.
• Treatment times are much shorter.

Different kinds of stereotactic radiosurgery may be used, depending on the type of cancer and where it is located in the body. Stereotactic radiosurgery is used to treat brain and spinal cancers.

SBRT PLAN

Stereotactic body radiation therapy (SBRT) offers the same benefits as stereotactic radiosurgery and is used to treat similar tumours at extracranial sites like the head and the neck, Liver, Pancreas, Bones and any other sites needed.

DIBH- Deep inspiration breath hold (DIBH) is a technique that takes advantage of a more favorable position of the heart during inspiration to minimize heart doses over a course of radiation therapy. When one takes a deep breath and holds it, her diaphragm pulls the heart away from the chest. This is known as a deep inspiration breath hold (DIBH). The radiation is delivered to the breast while the patient is holding her breath deeply for 20 seconds. This provides protection for the heart. This benefit is the greatest in those patients with left-sided disease and those receiving IMC irradiation. DIBH has also been shown to decrease dose to the lungs.
