Title: PHOTOACOUSTIC IMAGE GENERATION DEVICE
Abstract:
Provided is a photoacoustic image generation device which uses an insert that generates photoacoustic waves from the vicinity of a tip of the insert, wherein detection is possible as to whether the output of the photoacoustic waves from the vicinity of the tip of the insert is normal. The present invention comprises: an insert (15) having a photoacoustic wave generation unit; an acoustic wave detection unit (11) that detects photoacoustic waves and reflected acoustic waves; a photoacoustic image generation unit (24) that generates a photoacoustic image on the basis of the photoacoustic waves; an image output unit (26) that outputs, to an image display means, information based on the photoacoustic waves detected by the acoustic wave detection unit 11; a tip position detection unit (29) that detects that a tip portion of the insert (15) is disposed at a predetermined detection position relative to the acoustic wave detection unit (11); and a control unit (28) that, if it is detected that the tip portion of the insert (15) is positioned at the predetermined detection position, displays, on the image display means, information based on the strength of a detection signal of the photoacoustic waves generated from the photoacoustic wave generation unit in an insert detection mode.
