Abstract
Provided are a photoacoustic image generation apparatus and an insert that can evaluate whether a plurality of materials with different absorption wavelengths are present in the vicinity of a puncture needle, without preparing a plurality of light sources. A puncture needle is at least partially inserted into a subject. An optical fiber guides light with a first wavelength. A light emitting portion emits the light guided by the optical fiber. A light absorption/conversion member absorbs the light with the first wavelength emitted from the light emitting portion and converts the light with the first wavelength into light with a second wavelength. In addition, the light absorption/conversion member generates photoacoustic waves with the conversion into the light with the second wavelength.
