摘要： An acoustic-wave measuring apparatus includes a holding unit configured to hold a subject and an irradiation unit configured to irradiate the subject with light. An acoustic-wave detecting unit detects acoustic waves generated in the subject due to irradiation with the light; an image pickup unit acquires an image of the subject; and a measurement position on the image acquired by the image pickup unit is designated. A coordinate transforming unit transforms the coordinates of the measurement position on the image to coordinates of a corresponding position on the holding unit; and a position control unit moves at least one of the irradiation unit and the acoustic-wave detecting unit to the corresponding position on the holding unit.

摘要： A photoacoustic imaging apparatus includes a signal processor. The signal processor includes an adding unit configured to add received signals obtained by acoustic wave detecting devices to obtain a summed signal, a normalizing unit configured to normalize the summed signal for each acoustic wave detecting device with reference to an amplitude value in the received signal in the acoustic wave detecting device at the time when a maximum amplitude value in the summed signal is obtained to obtain a normalized signal, a reducing unit configured to subtract the normalized signal from the received signal for each acoustic wave detecting device to obtain a reduced signal in which the amplitude value in the received signal at the time when the maximum amplitude value in the summed signal is obtained is reduced, and an imaging unit configured to generate image data using the reduced signals.

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.
