摘要
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.
