    Abstract: Three-dimensional (3D) reconstruction of a cell includes adjusting a current set of projection images according to a priori knowledge to produce adjusted projection images, for example, based on probability masks and/or Bayesian analysis of multiple similar objects in the same sample. A reconstruction algorithm processes the adjusted projection images to generate a 3D image. The 3D image is further adjusted according to the a priori knowledge to generate an adjusted 3D image. Criteria for process completion are applied to determine whether the adjusted 3D image is adequate. Otherwise, a set of pseudo projections are computationally created at the same projection angles as the current set of projection images and then compared to the current set of projection images to produce a set of new projections, wherein the new projections are input again to the reconstruction algorithm and the steps of the method are repeated until the adequacy criteria are met.

    Abstract: A cytological system dynamic normalization of a normal threshold. An analysis score from a slide is compared against a threshold to determine whether or not the slide is normal or requires microscopy review. The normal threshold is dynamically adjusted using a three step process. The process is implemented on an automatic cytology system. The first step is initial calibration of the system to determine an initial threshold. The second step is a running adjustment of the normal threshold in response to the presentation of new slides to the automatic cytology system. The third step is the batch certification of every slide. The threshold may be adjusted for an analysis score, a quality control score, or a screening score.

    Abstract: 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.

    Abstract: Method and apparatus for reducing X-ray dosage required for xeroradiographic examinations without reducing the relative information capacity of the images produced during the examination. In particular, a charged xerographic plate is positioned adjacent the object to be examined and penetrating X-ray radiation is projected through the object onto the plate surface, forming a latent electrostatic image on the surface of the plate. The penetrating radiation utilized is of a substantially lower dosage than normally utilized. The image is then partially developed with developing powder and the partially developed image is then charged and exposed to substantially uniform radiation. The exposed charged image is finally developed by applying additional developing powder thereto resulting in an enhanced image or signal.

    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 process includes coating a cylinder having an inner wall and a cylinder axis with a gel coating on the inner wall. Then a specimen mixture including solvent is made to flow through the cylinder while the cylinder is being continuously rotated. The specimen mixture is initially directed to flow along the cylinder axis and such that specimen particles from the specimen mixture are accelerated off the cylinder axis toward the inner wall, so as to form a film of specimen particles embedded into the gel coating.

    Abstract: An optical tomographic system wherein the localization of secondary emitters within an object of interest is determined using the temporal signatures of secondary emission arising from the object being illuminated by an external primary source beam that is non-parallel, such as a cone beam, while the object is moving relative to said beam in a controlled manner. A unique set of secondary emitter spots is localized within the object and, when combined with a computed 3D reconstruction of the object from its primary cone beam projections, creates an image of the secondary emitters in the object so as to enable quantitative three-dimensional imaging of fluorescent labeled molecular probes in a biological cell, for example.
