Numerical Study of Photoacoustic Pressure for Cancer Therapy
Applied Sciences, 2016 A commonly used therapy for cancer is based on the necrosis of cells induced by heating through the illumination of nanoparticles embedded in cells. Recently, the photoacoustic pressure shock induced by the illumination pulse was proved and this points ...

Shape Optimization of an Open Photoacoustic Resonator
Applied Sciences, 2021 Photoacoustic (PA) measurements with open resonators usually provide poor detection sensitivity due to signal leakage at the resonator opening. We have recently demonstrated three different approaches for modelling the photoacoustic signal of open ...

Photoacoustic thermography of tissue [PDF]
Journal of Biomedical Optics, 2014 Photoacoustic (PA) techniques can measure temperature in biological tissues because PA signal amplitude is sensitive to tissue temperature. So far, temperature-measuring PA techniques have focused on sensing of temperature changes at a single position. In this work, we photoacoustically measured spatial distribution of temperature in deep tissue.

Photoacoustic Imaging in Ophthalmology
International Journal of Ophthalmology & Eye Science, 2015 Photoacoustic (PA) imaging is a rapidly developing new biomedical imaging modality. Unlike existing ophthalmic imaging technology such as fundus photography, optical coherence tomography, fluorescein and indocyanine green angiography, and ultrasound, photoacoustic imaging combines the advantages of optical excitation and acoustic detection.
