Abstract

Disclosed are photoacoustic imaging systems, and laser energy correction methods and prompting methods therefor, and photoacoustic imaging systems. The method includes: controlling a laser to transmit a first optical pulse to a target tissue; receiving a first acoustic wave generated by the target tissue absorbing the first optical pulse to acquire a first photoacoustic signal, and receiving a third acoustic wave generated by a marker absorbing the first optical pulse to acquire a third photoacoustic signal; controlling the laser to transmit a second optical pulse to the target tissue; receiving a second acoustic wave generated by the target tissue, and receiving a fourth acoustic wave generated by the marker; correcting a signal intensity of the first photoacoustic signal based on a signal intensity of the third photoacoustic signal together with a first absorption coefficient of the marker with respect to the first optical pulse, and correcting a signal intensity of the second photoacoustic signal based on the fourth photoacoustic signal together with a second absorption coefficient of the marker with respect to the second optical pulse; and acquiring an oxygen saturation of the target tissue based on the corrected signal intensity of the first photoacoustic signal and the corrected signal intensity of the second photoacoustic signal.
