Stereotactic radiation therapy uses precisely focused radiation beams to treat tumors in various parts of the body. Stereotactic radiosurgery (SRS) is used to treat tumors in the brain and can also be applied to a variety of neurological conditions. When stereotactic radiation therapy is used to treat tumors in other parts of the body (such as the lung, breast and prostate) it is called Stereotactic Ablative Body Radiotherapy (SABR). 


The aim of the Stereotactic Interest Group of Australasia (SIGA) is to establish collaboration between various medical specialists (Radiation Oncologists, Radiation Therapists, Radiation Oncology Medical Physicists, Neurosurgeons and other subspecialists) who promote the use of stereotactic radiation therapy and radiosurgery in the management of both intra and extracranial diseases. 

The use of stereotactic radiation treatments has expanded in the Australasian region. SIGA works to establish a regular forum to discuss and facilitate best-practice stereotactic radiation therapy/radiosurgery treatment, to share knowledge and experience that may then encourage collaborative research. 


The purpose of SIGA is to enable sharing of knowledge and experience to facilitate the delivery of best-practice stereotactic radiation therapy. The main project that SIGA delivers is a one-day workshop that is usually held in conjunction with the SABR Symposium.
