PROBLEM TO BE SOLVED: To make it possible, when making sure the position of an object inserted into a subject using a photoacoustic image, to determine whether or not the inserted object, which is indicated on the photoacoustic image, is in a direction directly below the probe.SOLUTION: Among plural photoacoustic images based on photoacoustic detection signals detected in photoacoustic waves in plural postures during peak search mode, peak discrimination means 31 specifies the photoacoustic image having the detected highest intensity photoacoustic detection signal on the basis of the plural photoacoustic images. Posture determination means 32 determines whether or not the posture of a probe 11 when detecting the photoacoustic waves of the photoacoustic image generation source in normal mode coincides with the posture of the probe 11 when detecting photoacoustic waves of the generation source for the photoacoustic image specified by the peak discrimination means. Display control means 27 causes photoacoustic images to be displayed on a display screen, and, when the posture determination means 32 determines that the postures coincide, causes a message to that effect to be displayed on the display screen. |
