Abstract
The method and apparatus for analyzing particles and particularly blood cells by conveying the particles along a broad shallow path where the path is magnified and converted into a series of still frame images with multiple particles in individual images. The still frame images are manipulated and combined as digital images to generate measures of the blood cells in the overall fluid sample giving different selected measures, such as, particle count, particle count of different kinds of cells, cell area, and cell count of different predetermined categories of cell type.
