Document Type and Number:
Japanese Patent JP3130628
Kind Code:
B2
Abstract:
A device for identifying the kind of each particle detected by a particle detecting device such as imaging flow cytometer from detection signals obtained by passing therethrough a specimen, such as blood, in which various kinds of particles (blood corpuscles) exist intermixedly. Distribution characteristics (mean value, distribution width, etc.) of specific characteristic values previously sought on a known kind of reference particles are stored, the degree of similarity of the detected particle to the reference particles, that is, "probalibity of correctness of judgement at the time of judging the detected particle as of the same kind of the reference particles" is calculated in accordance with a predetermined rule from the detection signals of the detected particle representing the same characteristic values and the stored distribution characteristics of the reference particles, and the probabilities of calculated on the respective characteristic values are synthesized to judge whether the detected particle is of the same kind as the reference particles or not.
