Stereotactic frame for neuroradiology and -charged particle bragg peak radiosurgery of intracranial disorders

Image correlation of MRI and CT in treatment planning for radiosurgery of intracranial vascular malformations

“…The effectiveness of the stereotactic frame and mask and the accuracy of the correlation between CT and angiography have already been discussed in earlie~; reports [10,13]. However, the incorporation of MRI has resulted in some slight modification of our procedures, a better rmderstanding of the source and magnitude of errors in the repositioning of the patient within the mask, and an increased confidence in the accuracy of our ability to target and irradiate a desired volume of tis~me within the brain.…”

“…The neuroradiological procedures are performed with the patient fixed in the stereotactic fra1ne and removable mask system, as described in Ref. (10]. 'l;'he patient wears a mask constru.cted of thermoplastic that conforms very accurately to the contours of the head.…”

Stereotactic radiosurgery and the linear accelerator: accelerating electrons in neurosurgery

“…11,27 Other investigators worked with particle beam radiosurgery systems at the University of California at Berkeley and in Boston. 23,33 Early radiosurgery researchers were aware of LINAC's potential in delivering targeted radiation. In 1974, Larsson, the head physicist in the collaborative group at Uppsala University with Leksell, wrote:…”

Verbesserte Lagerungsreproduzierbarkeit eines nichtinvasiven Hochpräzisionsmaskensystems in der stereotaktischen Radiotherapie durch eine integrierte Kieferfixierung

“…Sie wurden aus rigiden, invasiven Fixierungsmethoden, wie sie im Rahmen der Hochpräzisionsbestrahlung der Radiochirurgie zur Anwendung kommen, entwickelt. Technisch basieren diese Systeme auf der Kombination einer reversiblen Patientenfixierung mit einem stereotaktischen Koordinatensystem [2,3,9,13]. Diese Fixierung erfolgt entweder durch ein plastisch formbares Maskenmaterial [10] oder durch die Fixierung eines festen anatomischen Punktes (Oberkiefer, äußerer Gehörgang [4,13,15]) am stereotaktischen Rahmen.…”
