PHOTOACOUSTIC APPARATUS

摘要

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.

主权项

1. A photoacoustic apparatus, comprising:
a control unit configured to set a light irradiation timing; a light irradiation unit configured to irradiate a subject with pulsed light at the light irradiation timing; a reception unit configured to receive a photoacoustic wave generated as the subject is irradiated with the pulsed light from the light irradiation unit and to output a signal; an electrocardiogram acquisition unit configured to acquire an electrocardiogram signal of the subject; and a subject information acquisition unit configured to acquire subject information on the basis of the signal, wherein the control unit is configured to
set the light irradiation timing such that the subject is irradiated with the 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 the 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, andset 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.
