Stereotactic Radiosurgery

Stereotactic radiosurgery is a highly precise non-invasive treatment. It utilizes advanced equipment such as the Novalis Tx, now available at Hopeland’s new centre at the Life Hilton Hospital, which incorporates a six-dimensional robotic couch to concentrate radiation with sub-millimetre accuracy on both benign and malignant tumours. It is also utilized to treat certain functional abnormalities, such as to relieve pain caused by trigeminal neuralgia, as well as blood vessel abnormalities such as arteriovenous malformations.

Initially developed to treat targets in the brain, its use has now been expanded to include tumours involving the spine, as well as mobile targets in organs such as the lung and liver. This is possible by utilizing monitoring equipment such as the ExacTrac, which is able to detect and follow the movement of these tumours during therapy. The use of these techniques allows highly effective doses to be administered to the tumour with minimal dose to the surrounding normal tissue. The ability to deliver concentrated doses in a short amount of time allows for treatment in a single or a few sessions.
