An image processing equipment

摘要

The present invention relates to an equipment for analyzing the Ca<2><+> concentration in cardiomyocytes, wherein a fluorescent reagent is loaded into the cells to cause the carboxyl groups of the intracellular to be coupled with Ca<2><+>; the cells are subjected to a stimulative signal; pulse-excited light-pulses differing in wavelength are given to the cells during the vertical blanking period following a certain period of time after giving a stimulative signal to cause the cells to generate fluorescent images varying in fluorescence intensity due to the difference in the wavelengths of the pulse-excited light-pulses; the generated images are taken by a high-sensitivity television camera and displayed on a monitor; a plural number of image data are obtained by varying the timing of the stimulating signal, and the images are stored in an image memory; the image data are accessed through a CPU to two-dimensionally analyze the change in the shape of a single cardiomyocyte due to the contraction and the dynamic change in the intracellular Ca<2><+> concentration over time.
