Patent ID: 7578795

Claim:
A system for performing a medical examination comprising: means for presenting a series of sensory stimuli for perception by a patient; means for detecting electrical signals representative of the patient's evoked brain potentials in response to said sensory stimuli, comprising a plurality of electrodes configured to be connected to a scalp of the patient, wherein at least one electrode is configured to be placed over a visual cortex of the patient; means for amplifying said signals, connected to said means for detecting; means for converting said signals into digitized data, connected to said means for amplifying; means for recording said data, connected to said means for converting; means for measuring said data, connected to said means for recording; and a computer processor programmed to analyze said data and to compare said data to predetermined values to determine if said data is outside of predetermined ranges and thus indicates unreliable data results, connected to said means for measuring and to said means for recording, wherein said means for recording records each occurrence of data being outside of predetermined ranges, wherein said computer processor is programmed with a predetermined maximum value of a plurality of faults and is further programmed to continue to collect data notwithstanding detection of a fault until after determining said predetermined maximum value of said plurality of faults and is programmed to stop the collection of data after receiving an indication that the data collected is reliable, and wherein said computer processor is further programmed, upon stopping a collection of data after receiving said indication that the data collected is reliable, to determine if said data passes a scattering check.
