摘要： Methods and apparatus to diagnostic techniques which programmatically generate N-dimensional histograms from data obtained from volumetric data sets, such as those obtained using particle analyzers and flow cytometers. Received data is processed utilizing data shaping techniques such as noise and outlier filtering, segregation and amplification of desired data, and thresholding of data sets, to aid in the detection of abnormalities. In biological samples, such abnormalities are often indicative of disease, and therefore it is important to provide consistently accurate results. Populations of biological abnormalities may be detected and enumerated using multiple parameters, such as fluorescence, optical, and electrical parameters, and displayed in a manner which maximizes information content.

摘要： Embodiments of the present invention encompass automated systems and methods for analyzing immature platelet parameters in an individual based on a biological sample obtained from blood of the individual. Exemplary techniques involve correlating aspects of direct current (DC) impedance, radiofrequency (RF) conductivity, and/or light measurement data obtained from the biological sample with an evaluation of immature platelet conditions in the individual.

摘要： In accordance with the principles of the invention, methods, systems, and computer- readable mediums are provided for processing image data representing cellular analysis result data including accessing image data; generating an intensity histogram based on the image data; transforming the intensity histogram into a stepped image; performing normalized cross-correlation between the stepped image and a reference image to measure similarity; and determining an abnormality based on the measured similarity.
