As photoacoustic imaging (PAI) begins to mature and undergo clinical translation, there is a need for well-validated, standardized performance test methods to support device development, quality control, and regulatory evaluation. Despite recent progress, current PAI phantoms may not adequately replicate

Handheld imaging probes are needed to extend the clinical translation of optical elastography to in vivo applications, yet such probes have received little attention. In this paper, we present the first demonstration of optical palpation using a handheld probe. Optical

A Review of Mesoporous TiO2 Thin Films

Electronically, it behaves as a wide band gap (3.2 eV) semiconductor and exhibits memristor properties.2 Optically, TiO2 has high opacity with a very high refractive index3 (>2.4), and it exhibits strong absorbance in the UV range.
