Stereotactic radiosurgery using a linear accelerator.
A basic and clinical study of radiosurgery using the linear accelerator (Linac) system for unremovable deep-seated brain tumors is reported. A Komai stereotactic ring was used to locate the target coordinates. The patient was laid on the Linac treatment table and held in the head fixation system. Irradiation was given in five positions. The dose profile by film dosimetry and Rando phantom was s...
متن کاملLinear accelerator stereotactic radiosurgery for trigeminal neuralgia.
BACKGROUND Stereotactic radiosurgery is accepted as an alternative for patients with refractory trigeminal neuralgia, but existing evidence is fundamentally based on the Gamma Knife, which is a specific device for intracranial neurosurgery, available in few facilities. Over the last decade it has been shown that the use of linear accelerators can achieve similar diagnostic accuracy and equivale...
متن کاملA Novel Linear Accelerator Based Stereotactic Radiosurgery System
A novel platform for LINAC-based SRS treatment, the Edge, (Varian Medical Systems, Palo Alto, CA) offers multiple imaging modalities for treatment localization, including an optical surface monitoring system (OSMS) for surface tracking, 2.5 MV portal imaging, triggered monoscopic kV imaging to track intra-fractional motion, 4D CBCT to evaluate tumor motion offline, extended CBCT images by stitc...
متن کاملAccelerator-based stereotactic radiosurgery for brainstem metastases.
BACKGROUND Stereotactic radiosurgery represents a noninvasive alternative treatment for intracranial metastases. OBJECTIVE To investigate the treatment outcome of linear accelerator-based stereotactic radiosurgery (linac-SRS) for brainstem metastases. METHODS We retrospectively reviewed our database of patients who were diagnosed with brainstem metastases and underwent linac-SRS between 199...
متن کاملLinear accelerator stereotactic radiosurgery for vestibular schwannomas: a UK series.
AIMS To evaluate non-auditory toxicity and local control after linear accelerator stereotactic radiosurgery (SRS) for the treatment of vestibular schwannomas. MATERIALS AND METHODS The institutional policy was to use SRS for radiologically progressing vestibular schwannomas. Case notes and plans were retrospectively reviewed for all patients undergoing SRS for vestibular schwannomas between S...
