摘要： When a subject is pressed by a plate and an acoustic wave is received by a probe via the plate, the acoustic wave is refracted because of the difference between a sound velocity in the subject and a sound velocity in the plate. When the refraction is not considered, a reduction in resolution occurs. Weights for signals or virtual wavefronts corresponding to the signals to be added to one another are determined using a thickness of the plate, the sound velocity in the plate, the sound velocity in the subject, positions of image elements (pixels or voxels) for image information, and arrival times of the acoustic wave from an object that is a sound source. The signals or the virtual wavefronts corresponding to the signals are added to one another, thereby acquiring the image information.

摘要： A photoacoustic apparatus obtains information on a specimen by receiving photoacoustic waves which are generated from the specimen resulting from light irradiated to the specimen. The apparatus includes a light source for irradiating light to the specimen, an acoustic wave receiver for receiving the photoacoustic waves, and a light reflection member for causing the light, which is radiated out of the specimen by optical diffusion thereof after having entered an interior of the specimen from the light source, to reenter the interior of the specimen, wherein the light reflection member allows elastic waves to pass therethrough. As a result, a photoacoustic apparatus and a probe are provided which can confine scattered light from the specimen into the specimen, and which can reliably prevent photoacoustic waves from being generated from a receiving element region of the probe by the scattered light.
