Experimental setups for the imaging systems: (A) Commercial PA system (Vevo LAZR-X) equipped with ultrasound detector MX550D, of which the central frequency is 40 MHz. (B) Self-developed handheld photoacoustic real-time imaging system. The system includes a pulsed laser with repetition rate of 100 Hz, while the operation wavelengths for the signal port is from 680 to 980 nm, a XYZ scanning stage with a customized handheld fiber bundle hosted on it and a research ultrasound platform for processing the imaging purposes. The detector of the ultrasound platform is a 128-element linear transducer array, which is in the middle of the bifurcated fiber bundles.
