Photoacoustic imaging is a hybrid biomedical imaging technique, combining rich optical
contrasts and good acoustic resolution in deep tissues. As a noninvasive and nonionized …

Speed-of-sound and optical absorption reflect the structure and function of tissues from
different aspects. A dual-mode microscopy system based on a concentric annular ultrasound …

Frequency domain analysis of radio frequency signal is performed to differentiate between
different tissue categories in terms of spectral parameters. However, due to complex …

Photoacoustic (PA) spectral parameters, obtained using conventional frequency domain
analysis of photoacoustic power spectrum, bear complex relationship with absorber size …
