title: Preliminary experience with Brown-Roberts-Wells (BRW) computerized tomography stereotaxic guidance system.
abstract: The production model of the Brown-Roberts-Wells (BRW) computerized tomography (CT) stereotaxic guidance system is described. Hardware and software modifications to the original prototype now allow the system to be used independently of the CT scanner after an initial scan with the localizing components fixed to the skull. The system is simple and efficient, can be used universally with all CT scanners, and includes a phantom simulator system for target verification. Preliminary experience with 74 patients at two institutions is described. It is concluded that CT stereotaxic guidance systems will become important tools in the neurosurgical armamentarium, as they allow accurate approach to any target identifiable on the CT scan.
