Classification: CPC A  G | IPC G

Claim 0:
1. A photoacoustic image generation apparatus comprising:
an insert of which at least a tip portion is adapted to be inserted into a subject and which includes a light guide that guides light to the tip portion and a photoacoustic wave generation portion that absorbs the light guided by the light guide and generates photoacoustic waves;
an ultrasound probe that detects the photoacoustic waves emitted from the photoacoustic wave generation portion and detects reflected acoustic waves reflected by transmission of acoustic waves to the subject; and
a processor,
wherein the processor configured to:
generate a B mode acoustic image on the basis of the reflected acoustic waves detected by the ultrasound probe,
generate a photoacoustic image on the basis of the photoacoustic waves detected by the ultrasound probe,
output a display image obtained by synthesizing the B mode acoustic image and the photoacoustic image,
determine a resolution of the B mode acoustic image, and
control a detection frequency of the photoacoustic waves used in a case where the photoacoustic image is generated based on the resolution of the B mode acoustic image forming the display image in order to change a size of bright point indicating the tip of the insert in the photoacoustic image forming the display image.
