1多焦点多光子显微成像经典数据压缩应用研究显示文摘该文针对多焦点多光子显微镜被越来越多地用于生物组织的三维成像。由于三维成像的实时图像数据巨大,开发实时压缩算法将有助于大规模图像数据的采集和存储。基于霍夫曼编码的无损压缩算法和基于离散余弦变换的JPEG有损压缩算法,对多焦点多光子显微镜成像数据的压缩进行初步研究。实验结果表明,基于霍夫曼编码的无损压缩算法压缩率稍低,但无图像信息丢失;基于JPEG编码的有损压缩算法具有较高的压缩率,但是图像信息会有一定程度的丢失。王瑞荣 何峰 丁颖 金朝阳 王建中 薛安克 Peter TC SO 2010杭州电子科技大学学报(自然科学版)2010,30,4:0
2Wide-field three-photon excitation in biological samples显示文摘Three-photon wide-field depth-resolved excitation is used to overcome some of the limitations in conventional point-scanning two-and three-photon microscopy.Excitation of chromophores as diverse as channelrhodopsins and quantum dots is shown,and a penetration depth of more than 700μm into fixed scattering brain tissue is achieved,approximately twice as deep as that achieved using two-photon wide-field excitation.Compatibility with live animal experiments is confirmed by imaging the cerebral vasculature of an anesthetized mouse;a complete focal stack was obtained without any evidence of photodamage.As an additional validation of the utility of wide-field three-photon excitation,functional excitation is demonstrated by performing threephoton optogenetic stimulation of cultured mouse hippocampal neurons expressing a channelrhodopsin;action potentials could reliably be excited without causing photodamage.Christopher J Rowlands Demian Park Oliver T Bruns Kiryl D Piatkevich Dai Fukumura Rakesh K Jain Moungi G Bawendi Edward S Boyden Peter TC So 2016Light(Science & Applications)2016,5,1:0
