Patent number: 11759167Abstract: Systems and methods of facilitating the viewing of interventional instruments (e.g., needles, catheters, guidewires, vascular filters, biopsy probes) are disclosed herein. In one embodiment, a portable, handheld or cart-based ultrasound imaging machine is connected to an external laser light source that transmits laser light to a tip of an interventional instrument via one or more optical fibers. The laser light is absorbed at the distal tip of the instrument and generates a photoacoustic signal. The ultrasound imaging machine creates an image by combining data from the received photoacoustic signals with ultrasound echo data to show both tissue in a region of interest and the tip of the interventional instrument.Type: GrantFiled: July 2, 2021Date of Patent: September 19, 2023Assignee: FUJIFILM SonoSite, Inc.Inventors: Qinglin Ma, Kerem Karadayi

Patent number: 11096657Abstract: A laser light source transmits laser light to a tip of an interventional instrument such as a needle via an optical fiber. The laser light is absorbed at the distal tip of the instrument and generates a photoacoustic signal. The laser light source is configured to receive a trigger signal from an ultrasound machine when a laser pulse is to be produced. The light source signals the ultrasound machine when an optical connector is connected to the laser light source to automatically begin a needle tip (NTV) visualization mode. If the optical connector is removed from the laser light source, the laser light source stops producing laser light pulses.Type: GrantFiled: June 2, 2017Date of Patent: August 24, 2021Assignee: FUJIFILM SONOSITE, INC.Inventors: Qinglin Ma, Paul Thurman Dunham, Keith David Williams, Hiroshi Murakami, Wealth Salvador, Carl Fabian, Brian R.
