Critical Reviews in Neurosurgery, 1999
This review looks at papers dealing with radiosurgery for tumors, cavernous malformations, and arteriovenous malformations. The tumors were meningiomas, many of them at the base of the brain, and the results were excellent. One paper used the gamma knife for patients with cavernous malformations.

The Radiobiology of Radiosurgery
Neurosurgery Clinics of North America, 1999Radiosurgery is the precise and complete destruction of a chosen target containing healthy or pathological cells, without significant concomitant or late radiation damage to adjacent cells. This article discusses briefly the many uses of radiobiology and considers variables in the treatment, such as dose rate, dose homogeneity, and the issue of ...

1993
Since 1982 a series of 11 epileptic patients have been treated with stereotactic radiosurgery. Patients were intracranially recorded with cortical and deep electrodes until the location of the epileptogenic focus was determined. A deep electrode was stereotactically placed at this point to confirm the accuracy of the location.

The most important imaging technology for GKNS continues to be magnetic resonance. The introduction of 3 Tesla machines permits quicker studies with better signal to noise ratio. The more powerful magnet increases the chances of heating the points of contact between patient and frame, but this has been solved with non-conducting nuts. There are several

Radiosurgery for pituitary adenomas
Clinical Endocrinology, 2004The role of irradiation in the management of pituitary adenomas is not well defined. Nevertheless, patients with residual or recurrent tumours have been treated with conventional external-beam radiotherapy and more recently with highprecision stereotactic techniques of stereotactic radiosurgery (SRS) and stereotactic radiotherapy (SRT).

Medical Dosimetry, 2013
Performances of radiosurgery of intracranial lesions between cone-based Linac system and Tomotherapy-based system were compared in terms of dosimetry and time. Twelve patients with single intracranial lesion treated with cone-based Linac radiosurgery system from 2005 to 2009 were replanned for Tomotherapy-based radiosurgery treatment.

Radiosurgery in dentistry: a review.
La Clinica terapeutica, 2019The aim of the present study was to analyse the clinical potential of radiosurgery applied to modern dentistry through a revision of the indexed literature. Radiosurgery represents a recent form of electrosurgery working at a frequency of 3.0-4.0 MHz. The depth of penetration of the waves is inversely proportional to the frequency.

Neurosurgery Clinics of North America, 1990
During the past decade, multiple linear accelerator (LINAC) radiosurgical systems have been developed. By measuring beam energy, beam accuracy, and dose gradient, it is possible to compare them to the older radiosurgical device, the gamma knife. LINAC systems appear to be advantageous in terms of cost, variety of collimator sizes available, and ...

Neurosurgery, 1999
Although the application of stereotactic radiosurgery for the management of functional brain disorders began in 1951, almost 50 years elapsed before it received appropriate attention. Radiosurgical techniques are used to create image-guided, physiological inactivity or focally destructive brain lesions without neurophysiological guidance.

Editorial: Epilepsy and radiosurgery
Journal of Neurosurgery, 2012Usami and colleagues4 from the University of Tokyo provide data on 7 patients who underwent Gamma Knife surgery (GKS) for mesial temporal lobe epilepsy (MTLE) between 1996 and 1999. Five of the 7 patients received a maximum radiosurgery dose of 50 Gy, which led to significant reduction in seizures in all 4 patients who underwent follow-up.
