1. Apparatus for the diagnosis of pathologic turbulent arterial blood flow in a patient comprising:

  • wave sensing means positioned at a plurality of spaced sites on the patient for generating a corresponding plurality of space time signals responsive to energy waves propagated from a site of arterial blood flow;

    interfacing means responsive to each of the space time signals from said wave sensing means for generating a vectorized data structure corresponding to the energy waves, said interfacing means including a frequency domain transform means for transforming desired portions of said plurality of said space time signals into a continuous sequence of time sampled sensor data; and

    processing means responsive to the vectorized data structures from said interfacing means for generating a report signal indicating the temporal waveform of the energy wave propagating from the site of turbulent arterial blood flow, the location and spatial configuration of that site.
