1. A method for detecting, recording, analyzing, and storing data of cranial vasculature of a patient with or without a cranial vascular abnormality, at a region of interest, including the steps of: (a) using an array of accelerometers engaged externally at a plurality of different positions against a patient's head, measuring acceleration and recording pressure wave/motion stimulation acceleration signal data from displacements of the skull at said plurality of positions on the skull, such displacements occurring from heartbeat-induced repeated pulsing of blood flow into the vasculature of the brain and resultant expansion and subsequent contraction of the blood vessels which moves the brain tissue due to such pulsing, the brain tissue movement causing resultant displacement of the skull at said plurality of positions on the skull, and (b) associating said signal data to characteristics of known signals of cranial vascular anomalies, in a computer, and finding any matches of said signal data to known signals of vascular anomalies, and further including (c) correlating signal data from multiple accelerometers of said array to determine a waveform signal common to the signal data from the multiple accelerometers and determining phase time differences among the signal data from the multiple accelerometers to thereby determine origins of a series of signal data collected by the multiple accelerometers from said displacements of the skull, thus localizing at least one signal from the signal data of the multiple accelerometers to define location of a structure of a vascular anomaly, and (d) storing results of the correlation and localizing steps as metadata in a database.
