An information processing apparatus includes an image data acquisition unit and a template data acquisition unit. The image data acquisition unit acquires a plurality of pieces of image data generated by performing a plurality of ultrasonic wave transmission and reception operations on a subject while changing an ultrasonic wave transmission and reception mode. The template data acquisition unit acquires a plurality of pieces of template data corresponding to the plurality of ultrasonic wave transmission and reception operations, respectively. The similarity information acquisition unit acquires information indicating a similarity between an image value sequence of the plurality of pieces of image data at a target position and a template data sequence of the plurality of pieces of template data at the target position.

A photoacoustic apparatus includes a light source; a receiving element configured to receive, at a plurality of positions, a photoacoustic wave generated through irradiation of a subject with light generated by the light source, and output a time-series reception signal; a signal data obtaining unit configured to obtain information that is based on a shape of the subject, generate reception signal data by reducing a data amount of the time-series reception signal on the basis of the obtained information that is based on the shape of the subject, and store the reception signal data; and an information obtaining unit configured to obtain information about the subject on the basis of the reception signal data stored in the signal data obtaining unit.

Photoacoustic apparatus

A specimen information acquisition apparatus includes a signal processor which can selectively operate in first and second modes. In the first mode, when a first group represents a group of devices among receiving devices and a second group represents at least a fraction of a group of devices other than the first group, a photoacoustic image and an ultrasonic image are obtained based on received signals from the first group and the second group, respectively. In the second mode, when a third group represents a group of devices having at least a fraction of a group of devices other than the first group and a fourth group represents at least a fraction of a group of devices other than the third group, a photoacoustic image and an ultrasonic image are obtained based on received signals from the third group and the fourth group, respectively.

Specimen information acquisition apparatus and specimen information acquisition method

There is provided a received data processing apparatus of photoacoustic tomography including a minimum constitution unit data composition unit that sequentially reads receiving digital signals from first storage units and composes minimum constitution unit data of the acoustic wave of the minimum constitution units by performing a delay-and-sum processing. A second storage unit stores the minimum constitution unit data of the entire region of the specimen, and an image construction unit constructs an image of the specimen based on the minimum constitution unit data stored in the second storage unit. A control unit sequentially stores the minimum constitution unit data calculated by the minimum constitution unit data composition unit in the second storage unit and reads the stored minimum constitution unit data of the entire region of the specimen to transmit the minimum constitution unit data to the image construction unit.

Received data processing apparatus of photoacoustic tomography

Generally, a photoacoustic signal has a wavelength longer than a general ultrasonic signal. That is, it does not matter even if at the time of acquisition of the photoacoustic signal, an element pitch of a probe is several times as large as at the time of acquisition of the ultrasonic signal. Thus, at the time of acquisition of the photoacoustic signal, a plurality of neighboring elements in a receiving element array are collectively considered as one element, and a phasing process is performed. As a result, the same effect as a plurality of phasing addition circuits are disposed in parallel is obtained, and not only a phasing addition process of the photoacoustic signal but also image reconstruction can be performed in real time at a high speed.

Subject information processing apparatus

A laminated structure of a flat plate type solid oxide fuel cell is made up of an alloy metal separator having a flat plate and a slit plate, wherein the flat plate is brought into contact with the slit plate after the slit plate is brought into contact with an air pole or the air pole is brought into contact with the slit plate after the slit plate is brought into contact with the flat plate, whereby a problem with the working of the alloy metal separator can be eliminated, and also the excellent performance of the flat plate type solid oxide fuel cell can be maintained by using the separator.
