Ultrafast photoacoustic cavitation pumped by picosecond laser for high-efficient and long-term shockwave theranostics. [PDF]
Photoacoustics, 2023 Photoacoustic (PA) theranostics is a new emerging field that uniquely combines diagnosis and treatment in one modality. However, its current status is compromised by the indispensable dependence on nonreversible phase-change nanoprobes that provides one-time-only action.

Efficient ultrafast photoacoustic transduction on Tantalum thin films
Applied Physics A, 2023 AbstractNano-acoustic strain generation in thin metallic films via ultrafast laser excitation is widely used in material science, imaging and medical applications. Recently, it was shown that transition metals, such as titanium, exhibit enhanced photoacoustic transduction properties compared to noble metals, such as silver.

FPGA-based reconfigurable processor for ultrafast interlaced ultrasound and photoacoustic imaging [PDF]
IEEE Transactions on Ultrasonics, Ferroelectrics and Frequency Control, 2012 In this paper, we report, to the best of our knowledge, a unique field-programmable gate array (FPGA)-based reconfigurable processor for real-time interlaced co-registered ultrasound and photoacoustic imaging and its application in imaging tumor dynamic response. The FPGA is used to control, acquire, store, delay-and-sum, and transfer the data for real-

High-resolution microscopy through optically opaque media using ultrafast photoacoustics
Optics Express, 2020 We present a high-resolution microscope capable of imaging buried structures through optically opaque materials with micrometer transverse resolution and a nanometer-scale depth sensitivity. The ability to image through such materials is made possible by the use of laser ultrasonic techniques, where an ultrafast laser pulse launches acoustic waves ...
