AGGREGATED CELL EVALUATION METHOD AND AGGREGATED CELL EVALUATION DEVICE

摘要

An aggregated cell evaluation apparatus 1 includes a laser light source 10, a speckle image acquisition unit 20, an SC calculation unit 30, an evaluation unit 40, and a memory unit 50. The speckle image acquisition unit 20 acquires a two-dimensional speckle image by forward scattered light generated in aggregated cells 90 by irradiation of the aggregated cells 90 with laser light output from the laser light source 10. The SC calculation unit 30 calculates a speckle contrast value K n of a speckle image In at each time t n , determines a maximum value K max among the speckle contrast values K 1 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 40 evaluates motion of the aggregated cells 90, based on the normalized speckle contrast value K n ' at each time t n . This realizes a method and an apparatus capable of readily evaluating the motion of aggregated cells.
