Abstract: A Ring-Arrayed Forward-viewing (RAF) ultrasound imaging and administration device combines an ultrasonic (US) US imager including a plurality of single element transducers arranged in a circular frame to define a ring array, and an instrument posture tracking circuit coupled to the ring array for performing RF (radio frequency) data acquisition with the plurality of ring-arrayed transducers. A needle holster is concentrically disposed in the ring array and is adapted to receive and direct an insertion instrument such as a needle, probe or extraction tool along an axis defined by a center of the ring array directed by the concentric needle holster. The tracking circuit includes a processor having instructions for instrument posture tracking and US imaging.
