By mapping the distribution of targeted plasmonic nanoparticles (NPs), photoacoustic (PA) imaging offers the potential to detect the pathologies in the early stages. However, optical absorption of the endogenous chromophores in the backgrou...
Investigation of the far-field approximation for modeling a transducer's spatial impulse response in photoacoustic computed tomography [0.03%]

When ultrasonic transducers with large detecting areas and/or compact measurement geometries are employed in photoacoustic computed tomography (PACT), the spatial resolution of reconstructed images can be significantly degraded. Our goal in...
Graphene-based contrast agents for photoacoustic and thermoacoustic tomography [0.03%]

Imaging of the cells and microvasculature simultaneously is beneficial to the study of tumor angiogenesis and microenvironments. We designed and built a fiber-optic based photoacoustic microscopy (PAM) and confocal fluorescence microscopy (...
Normal and melanoma skin visualized, quantified and compared by in vivo photoacoustic imaging [0.03%]
活体皮肤光声成像对正常和黑素瘤皮肤的可视化、量化及对比研究
Photoacoustic imaging (PAI) shows promise for skin cancer diagnosis by detecting chromophores like melanin, hemoglobin, lipids, and collagen. While most studies focus on malignant lesions, understanding normal skin variability across anatom...
