ABSTRACT:
Existing ultra-sonic echogram systems have limited resolution and contrast capabilities. The described system utilizes a pseudo-random frequency waveform and coherent signal processor to resolve image geometry simultaneously and non-ambiguously in radial distance (time) and velocity (frequency) domains. The high resolution and spectral detail provides a definitive data base for further data processing wherein vascular anomalies can be vividly displayed. Hazards associated with anesthesia, toxic injections, surgical entry and exposure to X-rays are avoided.
