Abstract
An apparatus for analyzing particle images includes a sheath flow cell for transforming a particle suspension flow into a flat flow surrounded by a sheath liquid, a light source for irradiating particles in the transformed particle suspension flow, a video camera for capturing particle images of irradiated particles, an image analyzer for analyzing the captured particle images, and a display device. The image analyzer including a calculator for measuring a projected area and perimeter of each captured particle image to calculate a particle diameter and circularity of each particle, a graph making device for making a histogram based on the particle diameter and for making a scattergram based on two parameters corresponding to the particle diameter and the circularity to allow the display device to display the histogram and the scattergram, a memory for storing each of the captured particle images, and a particle image recalling device for allowing the display device to collectively display the particle images stored by the memory.
