Abstract
At least a tip portion of a puncture needle 15 is inserted into a subject. The puncture needle 15 includes a light guide member which guides light from a laser unit 13, and a light emission unit which is provided in the vicinity of the tip portion and emits light guided by the light guide member, and generates a photoacoustic wave caused by light from the light emission unit in the tip portion. A probe 11 detects the photoacoustic wave from the puncture needle 15 in a state where the puncture needle 15 is inserted into the subject. A Photoacoustic image generation unit 25 generates a photoacoustic image based on the detected photoacoustic wave. A Light source control unit 30 controls the amount of light emitted from the light emission unit based on the photoacoustic image.
