Abstract

The invention discloses a three-dimensional super-resolution method based on Bessel film imaging, comprising the following steps: acquiring a three-dimensional image of a sample, wherein the three-dimensional image is obtained by quickly scanning a biological sample by using a piezoelectric ceramic displacement stage to collect fluorescent molecules emitted by stimulation in the sample; performinga radial fluctuation based super-resolution analysis on the three-dimensional image, and generating a first super-resolution image by analyzing a high-order variation of the fluorescent molecule withtime; guided by the first super-resolution image, the three-dimensional image is subjected to three-dimensional Bayesian analysis based on the scintillation and bleaching characteristics of fluorescent molecules to obtain a final super-resolution image. The invention extends the traditional two-dimensional super-resolution radial fluctuation analysis and two-dimensional Bayesian analysis to threedimensions for the first time, and realizes three-dimensional super-resolution; and the invention organically combines two super-resolution algorithms to improve the operation speed of the super-resolution algorithm and the spatial resolution of the super-resolution image.

Description

technical field [0001] The invention relates to the technical field of microscopic imaging, and more specifically, to a three-dimensional super-resolution method based on Bessel light sheet imaging. Background technique [0002] Light sheet fluorescence microscopy is a cutting-edge optical microscopic imaging method in the 21st century, which is of great significance to modern life science research. Traditional wide-field microscopy and confocal microscopy need to irradiate or scan the entire biological sample, which has high phototoxicity and low signal-to-noise images with poor axial resolution. The light sheet microscopy technology uses an excitation light sheet with a thickness of micron to excite the fluorescence of biological samples, and detects the fluorescence signal of the sample in a direction perpendicular to the direction of the excitation light sheet to form a two-dimensional image. Light sheet microscopy only excites fluorescent molecules near the focal plane...
