  • Cytological stain composition including verification characteristic
    Patent number: 6661501
    Abstract: The present invention relates to the analysis of cytological material. Specifically, the invention relates to stains and methods of producing the stains, methods of staining cells for cytological or histological analysis to contrast the nuclear portion of the cell from the cytoplasmic portion, and systems and methods for illuminating a cytological sample. The analysis can be automated or manual.
    Type: Grant
    Filed: October 29, 1999
    Date of Patent: December 9, 2003
    Assignee: Cytyc Corporation
    Inventors: David J. Zahniser, Norman W. Soule, Louise M. Isenstein

  • Filtering in 3-D visual system
    Patent number: 4884225
    Abstract: A series of spacial filters are used in a convolution process to determine location, size and orientation of bodies in an image. One series of spacial filters of different sizes is used to determine location and size. A second series is used to determine orientation and is a series of varying density, overlapping spacial filters. In particular, the series of spacial filters determines the spherical coordinants (r, .theta., .phi.) of bodies in an image of a muscle cell. The series of overlapping filters in one design have vector responses such that a resultant vector is defined. .phi. equals the angle of the resultant vector and .theta. is proportional to the length of the resultant vector. A series of one and two dimensional differential gaussian filters determine the cell boundaries.
