Title: PHOTOACOUSTIC IMAGE GENERATING DEVICE AND INSERTION OBJECT
Abstract:
[Problem] To acquire, for a photoacoustic image generation device and an insertion object, insertion object position information and surrounding environment information. [Solution] At least a part of a piercing needle (15) is inserted into a test subject by piercing the same. An optical fiber (153) guides light of a first wavelength, and an optical fiber (154) guides light of a second wavelength. A first light emission part (153a) emits the light guided by the optical fiber (153) and a second light emission part (154a) emits the light guided by the optical fiber (154). A light absorption member (51) absorbs the light of the first wavelength emitted from the first light emission part (153a) and generates a photoacoustic wave, and allows the light of the second wavelength emitted from the second light emission part (154a) to pass through.
