Analysis of factors associated with volumetric data errors in gamma knife radiosurgery.

25 Nov 2009 OBJECT: Gamma knife (GK) surgery is an important part of the treatment armamentarium for benign and malignant brain tumors. In general, quantitative volumetrical analysis of the tumor on neuroimaging studies is the most reliable method of assessment ... Read more...

Surgical displacement of risk organs to improve stereotactic radiotherapy for liver tumors.

30 Oct 2009 BACKGROUND AND OBJECTIVES: Precision irradiation may cure some liver malignancies, but adjacent stomach and colon may interfere with the delivery of the desired high doses due to the risk for serious side effects. METHODS AND RESULTS: Preferably ... Read more...

Proton beam radiotherapy versus three-dimensional conformal stereotactic body radiotherapy in primary peripheral, early-stage non-small-cell lung carcinoma: a comparative dosimetric analysis.

30 Oct 2009 PURPOSE: Proton radiotherapy (PT) and stereotactic body radiotherapy (SBRT) have the capacity to optimize the therapeutic ratio. We analyzed the dosimetric differences between PT and SBRT in treating primary peripheral early-stage non-small-cell ... Read more...

Technical information about 'Radiosurgery'

Definition: A radiological stereotactic technique developed for cutting or destroying tissue by high doses of radiation in place of surgical incisions. It was originally developed for neurosurgery on structures in the brain and its use gradually spread to radiation surgery on extracranial structures as well. The usual rigid needles or probes of stereotactic surgery are replaced with beams of ionizing radiation directed toward a target so as to achieve local tissue destruction.
