Abstract
A photoacoustic image generation apparatus includes: a puncture needle that generates photoacoustic waves; an ultrasound probe that detects the photoacoustic waves and reflected ultrasonic waves reflected by the transmission of ultrasonic waves; a processor that generates a color Doppler signal of a region of interest as a color Doppler measurement target, generates a photoacoustic image on the basis of the photoacoustic waves, and detects the position of a tip portion of the puncture needle on the basis of the photoacoustic image; and a controller that sets the region of interest such that the position of the tip portion of the puncture needle and a center position of the region of interest are separated from each other by a predetermined distance and sets the region of interest, following the movement of the tip portion of the puncture needle, in a state in which the distance is maintained.
