PHOTOACOUSTIC APPARATUS, OPERATION METHOD OF PHOTOACOUSTIC APPARATUS, AND PROGRAM |
摘要 |
A photoacoustic apparatus disclosed in the present specification includes: an acoustic wave transmission unit configured to transmit a transmission acoustic wave to a specific area; a control unit configured to control a transmission waveform of the transmission acoustic wave transmitted from the acoustic wave transmission unit; a light source configured to generate light emitted to an area including the specific area when the acoustic wave reaches the specific area; an acoustic wave reception unit configured to receive the acoustic wave and to output a time-series received signal; and a signal processing unit configured to acquire optical property information based on the time-series received signal, wherein the control unit controls the transmission waveform in such a manner that amplitude of a photoacoustic wave generated in the specific area is reduced by the transmission acoustic wave transmitted from the acoustic wave transmission unit. |
