(EN) Provided is a technology whereby more accurate evaluation is possible of the drug efficacy of a drug candidate chemical substance on a cell aggregates. A drug efficacy evaluation method that evaluates the drug efficacy of a chemical substance administered to a cell aggregate inside a fluid supported by a container and has: a step (step S102) in which a tomographic image is captured of a cell aggregate cross-section substantially matching the vertical plane; a step (step S105) in which the characteristics value of the cell aggregate is calculated on the basis of the tomographic image; and a step in which the drug efficacy of the chemical substance is determined on the basis of the characteristics value calculation results.
(ZH) 本发明提供一种药效评价技术，其能够更准确地评价作为候选药剂的化学物质对细胞集块的药效作用。在对投放于由容器承载的液体内的细胞集块的化学物质的药效进行评价的药效评价方法中，具备：取得工序(步骤S102)，其在与铅垂面基本一致的截面上对细胞集块进行断层摄像，取得断层图像；计算工序(步骤S105)，其基于所述断层图像计算细胞集块的特征量；以及，判定工序，其基于特征量的计算结果判定化学物质的药效。
