Abstract

A photoacoustic imaging system detecting ultrasound generated by pulse-modulated mid-infrared light irradiation is proposed and developed. Based on the spectra obtained with this method, we used SVM to derive the optimal combination of two wavelengths for separating muscle and fat, and achieved imaging using this combination.
