Stereotactic radiosurgery gives one high dose of radiotherapy from many different angles precisely targeted at the tumour.
Stereotactic radiosurgery is used for small tumours with well-defined edges. It is a type of image guided radiotherapy. This type of radiotherapy is mostly used to treat brain tumours, such as acoustic neuromas, pituitary adenomas, haemangioblastomas or secondary brain tumours. It is also used for spinal cord tumours. Stereotactic radiosurgery gives a high dose of radiotherapy without harming surrounding normal tissues.
