Methods and apparatus for immunoploidy analysis

Claim 1

An interactive method of analyzing a population of cells for a predetermined material with a digital image processing means, said method comprising the steps of: optically marking cells in the population for a first particular visual morphological feature, which includes binding a chromogen to a specific protein in the cytoplasm of the cells, to allow visualization of morphological characteristics of the cells; optically enhancing the predetermined material on cells in the cell population, which includs staining nuclear DNA in the cells which causes the cytoplasm to be destroyed; providing a magnified image of a plurality of cells in a field of view from the population to a user-observer, through the use of said digital image processing means, and allowing viewing of the optically-marked morphological feature of the cells and of the optically-enhanced material for the cells in the field of view, by digitizing and separating the image into two separate images where, in the first image, the DNA stained areas are visible and, in the second image, the optically-marked cytoplasm areas are visible, and by combing the two image areas and marking those cells which contain optically-marked cytoplasm areas; gating the cells in the field of view of the combined image into one of several subpopulation classifications based upon the optically-marked cell cytoplasm image and the stained nuclear DNA image as viewed by the user-observer; measuring with the digital image processing means the optical density of the nuclear DNA material on cells of the gated subpopulation, and generating with the digital image processing means a quantitation based on the measurments of the nuclear DNA material of the cells.
