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.

Abstract: An ultrasonic imaging configuration rendering an image based on a reflected beam aligned with a needle insertion axis provides enhanced images and guidance. A percutaneous insertion guidance device for ultrasonic (US) imaging includes an US transducer and a reflector for redirecting imaging signals between the transducer and an imaged region. An enclosure or bracket is adapted to support the reflector at a predetermined angle based on a surgical target in the imaged region such that a forward beam direction from the transducer reflects in a direction of the needle insertion as the needle passes through a discontinuity or slot in the reflector. The resulting return signal is based on an axial alignment of the US signals with the needle travel towards the surgical target.
