摘要：
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.
