Generalized recovery algorithm for 3D super-resolution microscopy using rotating point spread functions

Abstract: Super-resolution microscopy with phase masks is a promising technique for 3D imaging and tracking. Due to the complexity of the resultant point spread functions, generalized recovery algorithms are still missing. We introduce a 3D super-resolution recovery algorithm that works for a variety of phase masks generating 3D point spread functions. A fast deconvolution process generates initial guesses, which are further refined by least squares fitting. Overfitting is suppressed using a machine learning determined … Show more

“…Although the imaging performance of these localization‐based axial SRFM methods is affected by many experimental factors, such as the marker labeling density, detector noise, optical system aberrations, refractive index mismatch, photon efficiency, and field‐dependent aberrations, it is possible to design the optimal PSF with few localization errors by considering the PSF as individual designing parameter, and analyzing and balancing the interactions among the pupil function, ambiguity function, Fisher information, CRLB, and the relevant experimental parameters mentioned above . Benefiting from the development of 3D localization‐based super‐resolution reconstruction algorithms, these PSF engineering techniques have become a powerful research tool for many challenging topics, being used for velocity measurement, dipole orientation analysis, spectral traits tracking, etc. More recently, Gustavsson et al.…”

“…For example: Assuming an input image patch of 64-by-64 pixels, with a cubic volume of 6.4×6.4×1 m 3 represented by close-packed voxels of size 16 3 nm 3 , the RAM requirement for the sensing matrix A with single float precision is approximately 152.6 Gigabytes. We note here that setting up the problem with Fourier transforms [7] can significantly reduce the RAM requirement, but relies on the convolution assumption that we explicitly would like to avoid as discussed in the previous section.…”
