The Mark III Scanner: A Compact Device for Multiple-View and Section Scanning of the Brain

A device for rectilinear and transverse-section scanning of the brain using 99m Tc pertechnetate is presented. The scanner has four detectors to view four different aspects of the brain simultaneously. A self-contained computer controls display and all automatic operations with no processing delay. This system permits more thorough studies with multiple rectilinear and transverse section views without moving the patient, precise orientation of views to each other and to the patient's position, minimal technician operations to assure simplicity and reliability, maximum physician operation to assure a complete examination, efficient transfer of information, and economy of design to encourage wide application.
