California Association of Neurological Surgeons' Emergency Services Committee report: guidelines for establishment of trauma centers.
The CANS supports the concept of organized neurological trauma care consisting of an appropriate amalgamation of prepared communities, institutions, and adequate numbers of committed neurosurgeons. It further supports the guidelines of the ACS regarding institutions designated to receive trauma cases. ⋯ It supports the concept of prehospital triage of trauma victims as conducted by well-trained field personnel and reasonable triage criteria agreed upon by the local neurosurgical community. It further supports audit systems that include neurosurgeons to assess and improve the quality of neurosurgical care.

A frameless stereotaxic integration of computerized tomographic imaging and the operating microscope.
A computer-based system has been developed for the integration and display of computerized tomography (CT) image data in the operating microscope in the correct perspective without requiring a stereotaxic frame. Spatial registration of the CT image data is accomplished by determination of the position of the operating microscope as its focal point is brought to each of three CT-imaged fiducial markers on the scalp. Monitoring of subsequent microscope positions allows appropriate reformatting of CT data into a common coordinate system. ⋯ The CT data are reformatted into a plane and orientation corresponding to the microscope's focal plane or to a deeper parallel plane if required. This reformatted information is then projected into the optics of the operating microscope using a miniature cathode ray tube and a beam splitter. The operating surgeon sees the CT information (such as a tumor boundary) superimposed upon the operating field in proper position, orientation, and scale.
