Title:
PHOTOACOUSTIC APPARATUS AND INFORMATION ACQUISITION APPARATUS
Document Type and Number:
WIPO Patent Application WO/2016/035344
Kind Code:
A1
Abstract:
A photoacoustic apparatus includes a light irradiation unit, an acoustic wave receiving unit that receives an acoustic wave generated by irradiating the object with light emitted from the light irradiation unit and that outputs an electric signal, a control unit that controls the light irradiation unit, and a processing unit that processes the electric signal. The control unit controls the light irradiation unit so that a density of a distribution of emission positions in a plurality of times of light emission by the light irradiation unit is higher in an inner part of the distribution of the emission positions than in an outer part of the distribution. The acoustic wave receiving unit outputs a plurality of electric signals corresponding to the plurality of times of light emission by receiving acoustic waves generated by the plurality of times of light emission. The processing unit acquires image data on the basis of the plurality of electric signals.
