摘要： Provided is a display data obtaining apparatus capable of, in photoacoustic tomography, reducing a fluctuation in sensitivity which depends on location for image reconstruction even in a limited measurement condition in which a photoacoustic wave generated in the entire subject cannot be obtained in a sufficient range. The display data obtaining apparatus includes: an acoustic wave detecting unit for detecting an acoustic wave generated from a subject irradiated with pulsed light to obtain a signal; a first data deriving unit for deriving first data exhibiting an optical characteristic distribution of the subject based on the obtained signal obtained by the acoustic wave detecting unit; a memory for storing spatial sensitivity distribution data specific to the display data obtaining apparatus; and a second data deriving unit for deriving second data exhibiting the optical characteristic distribution of the subject using the first data and the spatial sensitivity distribution data.

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. A correction table or a correction formula for correcting image distortion associated with refraction is provided. After image information is acquired, new image information is acquired in accordance with the correction table or the correction formula, and is displayed.

摘要： A measuring apparatus includes a shape maintaining member that maintains a shape of at least a part of a subject, an element that receives an acoustic wave through the shape maintaining member and converts the acoustic wave into a first electric signal, the acoustic wave being generated in the subject when the subject is irradiated with light, and a processing unit that generates image data using the first electric signal. The processing unit determines, on the basis of the first electric signal, a first time from when the acoustic wave is generated in the subject to when the acoustic wave reaches a reception surface of the element. The processing unit converts the first electric signal into a second electric signal using a difference between the first time and a second time in which the acoustic wave travels from a virtual detection region set near a subject-side surface of the shape maintaining member to the reception surface of the element, the second electric signal being assumed to have been obtained by receiving the acoustic wave at the virtual detection region.

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 biological information processing apparatus includes: a light source 11 that irradiates light 12 to a light irradiation region 13A on a test object 13; an acoustic wave detector 17 that detects an acoustic wave 16 generated by a light absorber 15 in the test object upon its absorption of the light, and outputs a detection signal; and an electronic control system 18 having an amplifier that amplifies the detection signal outputted from the acoustic wave detector 17. The electronic control system controls a gain of the amplifier in such a manner that a gain for a detection signal of an acoustic wave generated at a first location in the test object becomes larger as compared with a gain for a detection signal of an acoustic wave generated at a second location which exists nearer to the light irradiation region than the first location does.
