摘要： A method for 3D imaging of cells in an optical tomography system includes moving a biological object relatively to a microscope objective to present varying angles of view. The biological object is illuminated with radiation having a spectral bandwidth limited to wavelengths between 150 nm and 390 nm. Radiation transmitted through the biological object and the microscope objective is sensed with a camera from a plurality of differing view angles. A plurality of pseudoprojections of the biological object from the sensed radiation is formed and the plurality of pseudoprojections is reconstructed to form a 3D image of the cell.

摘要： A scanning method for scanning samples of biological cells using optical tomography includes preparing, acquiring, reconstructing and viewing three-dimensional images of cell samples. Concentration and enrichment of the cell sample follows. The cell sample is stained. Cells are isolated from the cell sample and purified. A cell/solvent mixture is injected into a gel by centrifugation. A cell/gel mixture is injected into a capillary tube until a cell appears centered in a field of view using a stopped-flow method. An optical imaging system, such as a fixed or variable motion optical tomography system acquires a projection image. The sample is rotated about a tube axis to generate additional projections. Once image acquisition is completed, the acquired image projections are corrected for errors. A computer or other equivalent processor is used to compute filtered backprojection information for 3D reconstruction.

摘要： A system for optical imaging of a thick specimen that permits rapid acquisition of data necessary for tomographic reconstruction of the three-dimensional (3D) image. One method involves the scanning of the focal plane of an imaging system and integrating the range of focal planes onto a detector. The focal plane of an optical imaging system is scanned along the axis perpendicular to said plane through the thickness of a specimen during a single detector exposure. Secondly, methods for reducing light scatter when using illumination point sources are presented. Both approaches yield shadowgrams. This process is repeated from multiple perspectives, either in series using a single illumination/detection subsystem, or in parallel using several illumination/detection subsystems. A set of pseudo-projections is generated, which are input to a three dimensional tomographic image reconstruction algorithm.

摘要： A flow optical tomography system includes a flow cytometer, and at least one reconstruction cylinder positioned around a capillary tube. A photon source and a photon sensor work together with a pulse height analyzer to provide a first trigger point for the beginning of an object or cell, and a second trigger point for the end of the cell. The trigger signal is received by the reconstruction cylinder. The reconstruction cylinder includes optical point sources having a selectable emission wavelength, disposed in a geometric pattern around the cylinder perpendicular to and concentric with the capillary tube axis that facilitate the acquisition of transmitted, attenuated projection images of the flowing cells. The sensors also collect projections of fluorescence emitted from tagged molecular probes associated with nuclear and/or cytoplasmic structures or cell membranes. The projections are algorithmically processed to provide three dimensional information about the cells and their disease state.

摘要： A computer aided biological specimen screener is responsive to a priori information about biological specimens. An automated slide classifier scans a slide specimen and generates a set of scores. The classification which results from this set of scores depends on a priori information concerning the patient, such as patient age and prior health history and diagnosis. Using the patient information and an appropriate score, the specimen is classified. A normal threshold used for classification is changed over a wide range depending on the specificity appropriate to a particular patient risk category. The sensitivity of the classification is automatically maximized for a predetermined normal specificity.

摘要： A method for automated cell enrichment preparation where biological cells are injected into a first subchamber and flowed through the first subchamber, through a large pore filter and into a second subchamber so that the large pore filter retains particles large particles in the first subchamber, while the biological cells pass through the first filter into the second subchamber and are retained by a small pore filter. After clearing, the biological cells are stained. A solvent exchange leaves the biological cells in solvent and they are released into a concentration module where a portion of the solvent is removed to form an enriched concentrated cell suspension.

摘要： A parallel-beam optical tomography system for imaging an object of interest includes a parallel ray beam radiation source that illuminates the object of interest with a plurality of parallel radiation beams. After passing through the object of interest the pattern of transmitted or emitted radiation intensities is magnified by a post specimen optical element or elements. An object containing tube is located within an outer tube, wherein the object of interest is held within or flows through the object containing tube. A motor may be coupled to rotate and/or translate the object containing tube to present differing views of the object of interest. One or more detector arrays are located to receive the emerging radiation from the post specimen magnifying optic. Two- or three-dimensional images may be reconstructed from the magnified parallel projection data.

摘要： A system and method for rapidly detecting cells associated with malignancy and disease using molecular marker compartmentalization includes an optical tomography (OT) or a flow optical tomography (FOT) instrument capable of producing various optical projection images (or shadowgrams) containing accurate density information from a cell or cells labeled with tagged molecular probes or stains, a computer and software to analyze and reconstruct the projection images into a multi-dimensional data set, and automated feature collection and object classifiers. The system and method are particularly useful in the early detection of cancers such as lung cancer using cells from sputum or cheek scrapings and cervical/ovarian cancer using a cervical scraping, and the system can be used to detect rare cells in specimens including blood.
