Radiosurgery is a procedure that precisely delivers large radiation doses to tumors and other relevant anatomical targets in one to five treatments.
Varian radiosurgery involves the use of sophisticated technology to ablate tumors or other abnormalities with non-invasive, high dose radiation while minimizing the exposure to surrounding healthy tissue. Starting from classical neurosurgical targets, SRS (stereotactic radiosurgery) is progressing to treat targets previously not considered candidates for high-dose, hypofractionated delivery. Varian radiosurgery can be used for treating benign, malignant, metastatic or non-oncologic targets. Benign lesions can include schwannomas, adenomas, neurofibromas and meningioma. Malignant lesions include astrocytomas and glioblastomas. Metastases to distant targets, such as brain or spine, can come from any malignant primary cancer, the leading ones of which are lung, breast, melanoma, and prostate. Non-oncologic targets include vascular malformations, trigeminal neuralgia and others prescribed by the doctor.
Varian has helped pioneer new stereotactic treatment technologies in use for the treatment of cancer and other conditions. Radiosurgery treatments take advantage of recent advances in proven technologies, including:
- Imaging with cone-beam CT
- Motion management
- Precision beam delivery with RapidArc®
- Treatment planning through Eclipse™
- Automated patient-positioning technologies
Radiosurgery treatments using Varian technology are helping expand the options available to multidisciplinary oncology teams to treat a wide variety of targets throughout the body, including:
- Benign brain tumors
