Claim 0:
1. An acoustic wave device comprising:
a probe;
a processor that irradiates inside of a subject with an ultrasonic beam or laser beam from the probe;
an insertion object that is capable of being inserted into the subject and has a photoacoustic wave generator at a distal end portion;
an insertion object laser light source that generates a photoacoustic wave from the photoacoustic wave generator by irradiating the photoacoustic wave generator of the insertion object with laser beam; and
a display,
wherein the processor is configured to
receive an acoustic wave emitted from a tissue of the subject to generate a tomographic image generating reception signal by irradiating the inside of the subject with the ultrasonic beam or the laser beam from the probe, and receive a photoacoustic wave by the photoacoustic wave generator to generate an insertion object image generating reception signal,
generate a tomographic image signal representing a tomographic image of the subject from the tomographic image generating reception signal,
generate an insertion object image signal representing an image of the distal end portion of the insertion object from the insertion object image generating reception signal,
detect a first signal width of the insertion object image signal having a signal strength of a predetermined ratio to a peak value of a signal strength in the insertion object image signal,
generate, in a case where the first signal width is larger than a predetermined second signal width, an insertion object display image signal having a center at a peak position where the signal strength of the insertion object image signal becomes the peak value and having a maximum width corresponding to the second signal width from the insertion object image signal, and generate, in a case where the first signal width is smaller than the second signal width, an insertion object display image signal having a center at the peak position and having a maximum width smaller than the second signal width from the insertion object image signal, and
superimpose the tomographic image of the subject and the image of the distal end portion of the insertion object to be displayed on the display on the basis of the tomographic image signal and the insertion object display image signal.
