摘要
Methods and systems to resolve positions of sample components in fluorescence stochastic microscopy using three-dimensional structured illumination microscopy (“3D-SIM”) are disclosed. In one aspect, components of a sample specimen are labeled with fluorophores and weakly illuminated with a frequency of light to stochastically convert a subset of the fluorophores into an active state. The sample is then illuminated with a three-dimensional structured illumination pattern (“3D-SIP”) of excitation light that causes the activated fluorophores to fluoresce. As the 3D-SIP is incrementally moved within the volume of the sample and images are recorded, computational methods are used to process the images to locate and refine the locations of the activated fluorophores thereby generating a super-resolution image of sample components.
