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.

摘要： A photoacoustic imaging apparatus performs imaging of an optical absorber. The photoacoustic imaging apparatus includes a light source, a detector configured to detect an acoustic wave generated from the optical absorber that has absorbed energy of light emitted from the light source, and a signal processing unit configured to form an image of the optical absorber. The signal processing unit stores information indicating whether a rate of change in pressure of the acoustic wave detected by the detector is positive or negative before performing a waveform process on the acoustic wave.
