We investigated a novel needle visualization using the PA effect to enhance needle-tip tracking. An optical fiber and laser source are used to generate acoustic waves inside the needle with the PA effect. Acoustic waves are generated along the needle. Some amount of acoustic energy leaks into the surrounding material. The leakage of acoustic waves is captured by a conventional US transducer and US channel data collection system. Then, the collected data are converted to a PA image. The needle-tip can be visualized more clearly in this PA image than a general US brightness mode image.
