  • Interactive method and apparatus for sorting biological specimens
    Patent number: 6252979
    Abstract: An interactive process for sorting biological specimens includes the steps of processing a biological specimen to provide an analysis score, sorting the biological specimens according to the analysis score into categories including: clearly normal, interactive review, and microscopy review, and selecting a field-of-view (FOV) for the biological specimens sorted into the interactive review category.

  • Method for cytological system dynamic normalization
    Patent number: 5627908
    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.
