The analysis of cell and pathogen movement and motility is a major topic in cell biology for which computerized methods are most needed. This study proposes a method to detect and track multiple moving biological objects in image sequences acquired through fluorescence video microscopy. The method enables the analysis of video microscopy image sequences in order to obtain reliable quantitative data such as number, position, speed and movement phases. The method consists of three stages. A stage of detection is performed through a multi-scale analysis of images using an undecimated wavelet transform. The next stage is the prediction of the state of each detected spot in the next frame using a Kalman filter and an adapted model. Then comes a stage of data association which constructs the tracks and refines the filters. Once all moving objects have been assigned with unique spatio-temporal paths, trajectories are analyzed in terms of different parameters relevant to the motility analysis of biological objects.

We describe a simple modification to a rigid endoscope so as to provide both high quality conventional endoscopic as well as and confocal endoscopic images of reasonably accessible regions of the body in real time. The systems are based around either host lenslet-array tandem scanning microscope together with laser illumination or a structured illumination approach together with a conventional incoherent illumination source. images taken in fluorescence are presented using this combined conventional and confocal endoscope.

Real-time optically sectioned microscopy is demonstrated using an AC-sensitive detection concept realized with smart CMOS image sensor and structured light illumination by a continuously moving periodic pattern. We describe two different detection systems based on CMOS image sensors for the detection and on-chip processing of the sectioned images in real time. A region-of-interest is sampled at high frame rate. The demodulated signal delivered by the detector corresponds to the depth discriminated image of the sample. The measured FWHM of the axial response de ends on the spatial frequency of the projected grid illumination and is in the pm-range. The effect of using broadband incoherent illumination is discussed. The performance of these systems is demonstrated by imaging technical as well as biological samples.

We have developed a novel confocal microscopy system, which can perform both axial and lateral scanning at an ultra high speed. A rotary mirror array (RMA) consists of 36 small mirrors deployed on the surface of a round plate with a small tilting angle and a discrete rotational symmetry. When the RMA rotates at a constant speed, the focal point is scanned inside a sample periodically and linearly. We have demonstrated a scanning rate of 2400 lines per second, which can be readily improved to more than 20000 lines per second. Our scheme can also be used in a fast scanning multi-photon microscope.

Recent developement in confocal microscope systems allow to tune the spectral characteristics of those elements which separate excitation and emission. The new devices replace the classical filter-devices, which have been used in fluorescence microscopy for many yeas. Excitation filters have been replaced by acousto optical filters, which work as multichannel dimmer devices and allow fine tuning of excitation energy as well as tunig the excitation ratio of multiple excitations. Emission filters have been replaced by tunable multiband detectors, which allow tuning of emission band width for higher efficiency and better band separation. The multiband detector also allows spectral scanning modes. Dichroitic beam splitters have been replaced by acousto optical beam splitters (AOBS((R))) giving significantly increased signal efficiency and allow fast switching of excitation modes without moving mechanical parts. All three devices touether lead to much better primary images, either giving highly improved signal to noise ratio or much less photobleaching (which is identically with viability of life samples).

We present results from 2D Fourier analysis on 3D stacks of images obtained by confocal laser scanning reflectance microscopy (CLSM) and two-photon fluorescence microscopy (2PM) on human skin in vivo. CLSM images were obtained with a modified commercial system (Vivascope1000(TM), Lucid Inc, excitation wavelength 830 nm) equipped with a piezo-focusing element (350 mum range) for depth positioning of the objective tens. 2PM was performed with a specially designed set-up with excitation wavelength 730 nm. Mean cell size in the epidermal layer and structural orientation in the dermal layer have been determined as a function of depth by 2D Fourier analysis. Fourier analysis on microscopic images enables automatic non-invasive quantitative structural analysis (mean cell size and orientation) of living human skin.

Recognizing spatial relationships of neuro-degeneration in brains exposed to organic solvents is difficult when working from 2-dimensional serial slices. Recent advances in software have allowed the assembly of serial sections of stained tissue into a 3-dimensional (3D) representations. Appropriately chosen stains indicative of specific pathology can be highlighted and the 3D representation of its spatial distribution within the organ displayed. The purpose of this work was to develop a method for visualizing the spatial distribution of neuronal degeneration following organic solvent exposure. A cupric silver stain highly specific for degenerating neurons was used to identify neuronal degeneration in 83 serial histologic sections of brains of rodents exposed to toluene.. Brain sections were scanned at 600 dpi using a grey-scale protocol. Scans were assembled into 3D images which were further processed into stereo pairs. Grey-scale scans were compared to the original sections in order to establish grey- scale ranges for healthy and damaged tissue and artifact staining. The respective categories then were assigned pseudo-colors to improve contrast.

Current high-performance computers and advanced image processing capabilities have made the application of three dimensional visualization objects in biomedical images facilitate the researches on biomedical engineering greatly. Trying to cooperate with the update technology using Internet, where 3-D data are typically stored and processed on powerful servers accessible by using TCPAP, we held the results of the isosurface be applied in medical visualization generally. So in this system we use the 3-D file format VRML2.0, which is used through the Web interface for manipulating 3-D models. In this program we implemented to generate and modify triangular isosurface meshes by marching cubes algorithm, using OpenGL and MFC techniques to render the isosurface and manipulate voxel data. This software is more adequate visualization of volumetric data. The drawbacks are that 3-D image processing on personal computers is rather slow and the set of tools for 3-D visualization is limited. However, these limitations have not affected the applicability of this platform for all the tasks needed in elementary experiments in laboratory or data preprocessed. With the help of OCT and MPE scanning image system, applying these techniques to the visualization of rabbit brain. constructing data sets of hierarchical subdivisions of the cerebral information, we can establish a virtual environment on the World Wide Web for the rabbit brain research from its gross anatomy to its tissue and cellular levels of detail. providing graphical modeling and information management of both the outer and the inner space of the rabbit brain.

The abundance of naturally fluorescing components (autofluorophors) encountered in environmentally sourced samples can greatly hinder the detection and identification of fluorescently labeled target using fluorescence microscopy. Time-resolved fluorescence microscopy (TRFM) is a technique that reduces the effects of autofluorescence through precisely controlled time delays. Lanthanide chelates have fluorescence lifetimes many orders of magnitude greater than typical autofluorophors, and persist in their luminescence long after autofluorescence has ceased. An intense short pulse of (UV) light is used to excite fluorescence in the sample and after a short delay period the longer persisting fluorescence from the chelate is captured with an image-intensified CCD camera. The choice of pulsed excitation source for TRFM has a large impact on the price and performance of the instrument. A flashlamp with a short pulse duration was selected for our instrument because of the high spectral energy in the UV region and short pulse length. However, flash output decays with an approximate lifetime of 18 mus and the TRFM requires a long-lived chelate to ensure probe fluorescence is still visible after decay of the flash plasma. We synthesized a recently reported fluorescent chelate (BHHCT) and conjugated it to a monoclonal antibody directed against the water-borne parasite Giardia lamblia. Fluorescence lifetime of the construct was determined to be 339mus +/- 14mus and provided a 45-fold enhancement of labeled Giardia over background using a gate delay of 100mus. Despite the sub-optimal decay characteristics of the light pulse, flashlamps have many advantages compared to optical chopper wheels and modulated lasers. Their low cost, lack of vibration, ease of interface and small footprint are important factors to consider in TRFM design.

En-face optical coherence tomography (OCT) employing parallel heterodyne detection technique is demonstrated for three-dimensional microscopy. To enable the use of commercially available CCD cameras as two-dimensional heterodyne detector arrays in OCT imaging, a frequency synchronous detection method is Employed. Depth-resolved, full-field images are acquired at 30 Hz video-rate without lateral scanning.
