Employed is an information acquisition apparatus which acquires characteristic information about an object using a reception signal of acoustic waves generated by the object that is irradiated with light, the apparatus having: region acquisition unit for acquiring information indicating a plurality of regions of mutually different characteristics, in the object; sound velocity determination unit for determining sound velocity in the plurality of regions, using the information indicating the plurality of regions; and characteristic information acquisition unit for acquiring the characteristic information about the object, using the sound velocity and the reception signal.

Information acquisition apparatus and signal processing method

The present invention has an objective to display information more suitable for searching for medical information. An information processing apparatus includes a display control unit configured to display, when a first medical information item included in a plurality of medical information items is associated with a second medical information item, an icon indicating that a medical information item related to the first medical information item is present, on a display unit in conjunction with a thumbnail of the first medical information item, wherein the display control unit performs, when the icon is selected, such control as to display a display information item indicating a relationship between the first medical information item and the second medical information item, on the display unit.

Information processing apparatus and information processing method with display of relationship icon

The present invention provides an image display system which can simplify an operation of an operator for displaying images appropriate for diagnosis. An image display system according to the present invention includes a first obtaining unit configured to obtain first image data piece, a second obtaining unit configured to obtain a first meta-information piece regarding the first image data piece, a third obtaining unit configured to obtain a second image data piece, a fourth obtaining unit configured to obtain a second meta-information piece regarding the second image data piece, and a display control unit configured to determine a superimposition style corresponding to a combination of the first and second meta-information pieces based on the first and second meta-information pieces and display a superimposition image of the first and second image data pieces in the superimposition style on a display unit.

Image display system, image display method, and program

An image processing apparatus includes an acquisition unit configured to obtain information indicating a discrepancy in the oxygenation index of a blood vessel related to a region of interest based on image data indicating a spatial distribution of an oxygenation index in a subject and information indicating the blood vessel related to the region of interest, and a display control unit configured to display an image on a display unit based on the information indicating the discrepancy in the oxygenation index of the blood vessel related to the region of interest, the image indicating a condition of a tissue included in the region of interest.

Image processing apparatus, image processing method, and non-transitory storage medium

A photoacoustic apparatus sets a light irradiation timing such that a subject is irradiated with pulsed light at least once within a period extending from a start timing determined on the basis of a generation timing of an R-wave in an electrocardiogram signal to a point at which a first time extending from the generation timing of the R-wave in the electrocardiogram signal to a generation timing of a T-wave in the electrocardiogram signal elapses, and sets the light irradiation timing such that the subject is not irradiated with the pulsed light in a period outside the period extending from the start timing to a point at which the first time elapses.

Photoacoustic apparatus

A photoacoustic apparatus includes a light irradiation unit configured to irradiate a subject with light a plurality of times; a driving unit configured to move a supporting member so that relative positions of the supporting member and the subject differ at each of the plurality of times; a plurality of transducers configured to receive acoustic waves generated through the plurality of times of irradiation and output a plurality of groups of reception signals corresponding to the plurality of times of irradiation; the supporting member configured to support the transducers such that directional axes of at least some of the transducers converge; a first memory configured to store the groups of reception signals; and a processing unit configured to obtain subject information at a target position by assigning, to each of the groups of reception signals, a weight corresponding to relative positions of the supporting member and the target position.

A photoacoustic apparatus disclosed herein includes a plurality of receiving elements which receive photoacoustic waves caused by irradiation of light from a light source to a subject and outputs reception signals and a signal data acquisition unit which generates and stores reception signal data by reducing a data amount of reception signals output from the plurality of receiving elements when a region where the directional axes of the plurality of receiving elements are gathered at a point is not included in a region of interest.
