AGGREGATED CELL EVALUATION METHOD AND AGGREGATED CELL EVALUATION DEVICE

摘要

An aggregated cell evaluation apparatus includes a laser light source, a speckle image acquisition unit, an SC calculation unit, an evaluation unit, and a memory unit. The speckle image acquisition unit acquires a two-dimensional speckle image by forward scattered light generated in aggregated cells by irradiation of the aggregated cells with laser light output from the laser light source. The SC calculation unit calculates a speckle contrast value K_n of a speckle image I_n at each time t_n, determines a maximum value K_max among the speckle contrast values K₁ to K_N, and normalizes the speckle contrast value K_n at each time t_n by the maximum value K_max to obtain a normalized speckle contrast value K_n′. The evaluation unit evaluates motion of the aggregated cells, based on the normalized speckle contrast value K_n′ at each time t_n.
