3D microscopy with a double-helix point spread function

3D microscopy with a double-helix point spread function

conference on Three-dimensional and multidimensional microscopy - image acquisition and processing XVI

Double-helix point spread function (DH-PSF) is an engineered three-dimensional (3D) PSF specifically designed for 3D position estimation and imaging. It exhibits two lobes that rotate continuously around the optical axis with propagation. An information theoretical analysis shows that the DH-PSF carries higher and more uniform Fisher Information than the standard PSF through the 3D volume of interest. Experiments with DH-PSF demonstrate nanometer scale position localization accuracies in all three dimensions. Further, a variety of microscopy techniques such as bright-field, dark-field, and fluorescence can be directly transformed into their DH-PSF counterparts by placing an appropriate phase mask in the imaging path. The flexibility and performance make the DH-PSF attractive for 3D position localization in both photon-limited and photon-unlimited regimes.

Fuzzy Logic Components for Iterative Deconvolution Systems

Fuzzy Logic Components for Iterative Deconvolution Systems

conference on Three-dimensional and multidimensional microscopy - image acquisition and processing XX

Deconvolution systems rely heavily on expert knowledge and would benefit from approaches that capture this expert knowledge. Fuzzy logic is an approach that is used to capture expert knowledge rules and produce outputs that range in degree. This paper describes a fuzzy-deconvolution-system that integrates traditional Richardson-Lucy deconvolution with fuzzy components. The system is intended for restoration of 3D widefield images taken under conditions of refractive index mismatch. The system uses a fuzzy rule set for calculating sample refractive index, a fuzzy median filter for inter-iteration noise reduction, and a fuzzy rule set for stopping criteria.

In recent development of fluorescence microscopy, the out-of-focus fluorescence background that arises when imaging deep inside biological tissues is critical in determining the image quality and penetration depth. Focal modulation microscopy (FMM) is an advanced fluorescence technique that can provide high subcellular resolution when imaging thick specimens mainly by preserving the signal-to-background ratio.

Phase microscopy has been widely used to acquire information about unstained transparent biological objects. These objects are well visualized by techniques such as Differential Interference Contrast (DIC) microscopy, but standard DIC systems don't provide quantitative phase information. Quantitative analysis is limited by the nonlinear relation between the intensity image and the object phase. In this work we combine nonlinearity concepts of the image formation process to model 3D DIC images, specifically the point spread function (PSF) formulation;capturing behavior of measured images along the optical axis that are not obtained when using other models. We verify our model by comparing simulated images to real measured images. This model is designed so that the reconstruction of the 3D properties of imaged specimens can be done in a simple form.

Three-dimensional and multidimensional microscopy: image acquisition and processing ix

作者： Larson, Jeffrey M. Nikon Instruments Inc. Melville NY 11747 United States

Deconvolution of confocal fluorescence images by maximum likelihood estimation (MLE) was investigated for its ability to increase the information content in the images. 3-D MLE algorithms, applied to confocal image stacks, increase lateral and axial resolution and result in a finer optical section. Contrast, especially at edges, is enhanced, improving the documentation quality of high magnification images beyond that possible by confocal microscopy alone. Axial smear associated with spherical aberration was not removed by deconvolution and a lateral thinning artifact was introduced. Single confocal images can be rapidly deconvolved by 2-D MLE by applying a two-dimensional point spread function and treating them as images of planar objects. The 2-D algorithm can also deconvolve a maximum projection of a stack. The method works best when there is a minimal overlap of fluorescent structures. The projection is treated as a two dimensional object. Intensity information excluded by the projection operation cannot be recovered. Deconvolution of images acquired with the pinhole opened to increase sensitivity closely matches images acquired through an optimal opening, although in 2-D MLE, colocalization cannot be distinguished from overlap and the integrity of quantitative data cannot be guaranteed. Properly applied, MLE deconvolution increases the useful information content of confocal images.

In confocal microscopy, target objects are labeled with fluorescent markers in the living specimen, and usually appear with irregular brightness in the observed images. Also, due to the existence of out-of-focus objects in the image, the segmentation of 3-D objects in the stack of image slices captured at different depth levels of the specimen is still heavily relied on manual analysis. In this paper, a novel Bayesian model is proposed for segmenting 3-D synaptic objects from given image stack. In order to solve the irregular brightness and out-of-focus problems, the segmentation model employs a likelihood using the luminance-invariant 'wavelet features' of image objects in the dual-tree complex wavelet domain as well as a likelihood based on the vertical intensity profile of the image stack in 3-D. Furthermore, a smoothness 'frame' prior based on the a priori knowledge of the connections of the synapses is introduced to the model for enhancing the connectivity of the synapses. As a result, our model can successfully segment the in-focus target synaptic object from a 3D image stack with irregular brightness.

A snapshot high-sampling image Mapping Spectrometer (IMS) is developed for hyperspectral microscopy, measuring datacube of dimensions 285x285x60 (x,y,lambda). microscopy IMS is designed to work at the Nyquist sampling limit to realize high resolution imaging. The spatial resolution is similar to 0.45 mu m with FOV similar to 130 mu m. The spectral working range is 500-700nm with similar to 8.3nm average spectral resolution. Preliminary tests have been implemented on its imaging performances.

We report on a deconvolution method developed in a Bayesian framework for adaptive-optics corrected images of the human retina. The method takes into account the three-dimensional nature of the imaging process;it incorporates a positivity constraint and a regularization metric in order to avoid uncontrolled noise amplification. This regularization metric is designed to simultaneously smooth noise out and preserve edges, while staying convex in order to keep the solution unique. We demonstrate the effectiveness of the method, and in particular of the edge-preserving regularization, on realistic simulated data.

We developed a compact polarization-converter using two liquid-crystal spatial-light-modulators with eight electrodes. The converter converted a linearly polarized beam to two orthogonal linearly polarized beams and a radially polarized beam, and the direction of the electric filed at the focal point were controlled three-dimensionally. We constructed a second-harmonic-generation microscope using the polarization-converter to observe three-dimensional molecular orientation and demonstrated the detectability of molecular orientation.

Multiple beam interference system is used in conjunction with a conventional scanning confocal microscope to examine the morphology and construction of 3-D images of Histolytic Ameba and parasite Candida Albicans. The present combination permits to adjoin advantages of both systems, namely the vertical high contrast and optical sectioning. The interference pattern obtained from a multiple internal reflection of a sample, sandwiched between the glass plate and the cover plate, was focussed on an objective of a scanning confocal microscope. According to optical path differences, morphological details were revealed. The combined features, namely improved resolution in z axis, originated from the interference pattern and the optical sectioning of the confocal scanning system, enhance the resolution and contrast dramatically. These features permitted to obtain unprecedented images of Histolytic Ameba and parasite Candida Albicans. Because of the improved contrast, several details like double wall structure of candida, internal structure of ameba are clearly visible.
