    Abstract: 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.

    Abstract: 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.

    Abstract: 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.

    Abstract: 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.

    Abstract: 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.

    Abstract: Motion of an object of interest, such as a cell, has a variable velocity that can be varied on a cell-by-cell basis. Cell velocity is controlled in one example by packing cells into a capillary tube, or any other linear substrate that provides optically equivalent 360 degree viewing access, so that the cells are stationary within the capillary tube, but the capillary tube is translated and rotated mechanically through a variable motion optical tomography reconstruction cylinder. The capillary tube motion may advantageously be controlled in a start-and-stop fashion and translated and rotated at any velocity for any motion interval, under the control of a computer program. As such, there are several configurations of the optical tomography system that take advantage of this controlled motion capability. Additionally, the use of polarization filters and phase plates to reduce light scatter and diffraction background noise is described.

    Abstract: A variable control displayed through a graphical user interface and linked to a control element. The variable control has graphical representations of readily identifiable and easy to use controls. These controls include at least one text box to display a value. The displayed value can be set by default, or to show the current state of the control element. The variable control also includes at least one range box for assigning a range unit that corresponds to the text box. The variable control also includes a slider control that is linked to the text box and is used to make coarse adjustments to the value displayed in the text box. A spinner is also linked to the text box and is used to make fine adjustments to the displayed value. In a preferred embodiment, the user can select a digit or several digits within the displayed value and adjust only the user-selected digit or digits. Also in a preferred embodiment, the range box automatically updates the range unit when the displayed value is adjusted beyond a predetermined range limit.
