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...
