Abstract:Ultraviolet photoacoustic microscopy (UV-PAM) has emerged as a promising medical imaging technique for alternative histopathology, relying on the inherent optical absorption of DNA/RNA. However, traditional UV-PAM faces resolution challenges compared to clinical histological methods, limiting the observation of cellular structures. This limitation stems from the constraints of conventional reflection-mode UV-PAM systems, utilizing opto-ultrasound beam combiners or ringshaped ultrasound transducers. These compo… Show more
