  • Patent number: 7494809
    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.

  • Patent number: 6181811
    Abstract: A method and apparatus for optimizing biological and cytological specimen screening and diagnosis. A slide review process is recommended for cytological specimen screening to identify abnormal sub-populations for further review and also diagnosis by a human expert. An automated screener processes a cytological specimen. Using a slide score generated by the automated screener, a slide review process using a slide score classification is determined. The recommendation of slide review processes improves overall performance of the screening process as measured by sensitivity to abnormal specimens, and at the same time reduces the work load of a human reviewer. The system also effectively and smoothly integrates the process of initial screening of the specimen with the process of further review of the specimen and final diagnosis of the specimen.

  • Patent number: 5787208
    Abstract: Image enhancement for a digital image, such as an image of a biological specimen mounted on a microscope slide or a cytological specimen is herein described. A digital representation of the image is dilated to produce a dilated image and eroded to provide an eroded image. The dilated image, eroded image and the digital representation of the image are then processed to produce an enhanced image.
