DEVICE AND METHOD FOR PROCESSING PHOTOACOUSTIC SIGNAL

摘要

To obtain an absorption distribution from a detected signal with a practical device. Light is applied to a subject, and a photoacoustic signal generated in the subjectA photoacoustic is detected. From the detected photoacoustic signal, a light differential waveform, which is a differential waveform of a temporal waveform of the light applied to the subject, is deconvolved. As a result of this deconvolution, an absorption distribution is obtained.

1. A photoacoustic signal processing device comprising:
a sampler that samples a photoacoustic signal generated in a subject due to light applied to the subject to provide a sampled photoacoustic signal; and a light differential waveform deconvolver that generates, from the sampled photoacoustic signal, a signal from which only a light differential waveform is deconvolved, the light differential waveform being a differential waveform of a temporal waveform of light intensity of the light applied to the subject.
