摘要： A free-lying cell classifier. An automated microscope system comprising a computer and high speed processing field of view processors identifies free-lying cells. An image of a biological specimen is obtained and the image is segmented to create a set of binary masks. The binary masks are used by a feature calculator to compute the features that characterize objects of interest including free-lying cells, artifacts and other biological objects. The objects are classified to identify their type, their normality or abnormality or their identification as an artifact. The results are summarized and reported. A stain evaluation of the slide is performed as well as a typicality evaluation. The robustness of the measurement is also quantified as a classification confidence value. The free-lying cell evaluation is used by an automated cytology system to classify a biological specimen slide.

摘要： Dynamic control of the processing flow of an image analyzer such as a biological specimen analyzer as processing proceeds. Data collected and processed from a specimen under analysis, such as a biological specimen on a microscope slide, determines the fate of further processing. If there is enough evidence, based on the data collected from a slide, to make a decision with sufficient confidence, the processing of the slide can be stopped and a decision may be rendered. By avoiding unnecessary additional computation system throughput may be enhanced. Otherwise, data collection and computation continues until either certain termination criteria are met or no more data is left to acquire. This slide-dependent control and decision making method flexibly limits the amount of computation required to reach a system decision about a specimen. By evaluating analysis processing continuously a maximum signal to noise ratio may be achieved by preventing additional noise from entering the analysis and thus swamping signal information.

摘要： A robust biological specimen classifier. An automated microscopy system obtains features from an image of a biological specimen slide. A computer system in the automated microscopy system computes feature variations. Clusters are created that comprise samples of similar characteristics. A cluster membership generator generates membership values for each cluster. Classifiers specialized to certain feature sets are used to provide independent outputs. These outputs are offset and biased by the output of the membership generator. The output of the adjusted classification values are summed to create a slide score output.

摘要： Reference information for a biological slide is obtained. The reference information normalizes the measured object features. Calibrated feature measurement, not based on absolute measurements, self adjusts to match the situation of each slide, where each slide is characterized by the reference information. The reference may be different from slide to slide because of the preparation variations. The calibrated features will not carry the inter-slide variations. In addition, the reference information provides a good indication of the slide condition such as dark stained, air dried, etc. which can be used as slide features for the specimen classification. No alteration of the current practice of specimen preparation is required. The many slide context dependent features improve the classification accuracy of the objects in a specimen.

摘要： 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.

摘要： An automated biological screening system obtains biological and procedural data from a slide set of a selected clinical laboratory. The integration system tests the data on standardized criteria and passes and fails the data in selected categories. The results of the assessment are used to make process adjustment recommendations based on the results of a laboratory process adjustment procedure. Assessment and adjustment may continue until data from a slide set from the selected clinical laboratory passes in each category. The integration system then sets up, calibrates and installs the automated biological screening system. During operation, the integration system continuously monitors biological data generated by the automated biological screening system. The biological data may also be stored in a central product/service database for additional monitoring. The integration system also serves as an objective standard for reviewing and improving laboratory practices.

摘要： Measurement of the optical transfer function of an optical system imaging a bar pattern. A one dimensional fast Fourier transform processes sampled image data from the bar pattern. A model of the system utilizes robust measurements of the period, duty cycle and center of each stripe in the pattern. A signal alias free optical transfer function is estimated from the plurality of one dimensional frequency representation of the signal. An idealized bar pattern synthesized from the measured parameters of period, duty cycle and the center of each stripe in the pattern generates an ideal optical transfer function. The noise reduced optical transfer function, OTF, is estimated from OTF of the signal and OTF of the synthesized bar pattern.
