Title:
METHOD FOR ASSESSING CELL STATE AND DEVICE FOR ASSESSING CELL STATE
Document Type and Number:
WIPO Patent Application WO/2019/175959
Kind Code:
A1
Abstract:
A microscope observation unit (1) acquires hologram data pertaining to a culture plate (12) that includes a colony (13), and a phase information calculation unit (22) and a moving image creation unit (23) perform prescribed processing on the data to thereby create a phase image. A texture feature value computation unit (241) and a texture feature image creation unit (242) perform statistical texture analysis on each small region of the phase image and create multiple types of texture feature images. A cell region extraction unit (243) extracts a colony region from a texture feature image, and an index value calculation unit (244) computes index values such as the mean or standard deviation from the feature values included in the colony region on the texture feature image. A state assessment processing unit (245) assesses whether there are undifferentiated aberrant cells in the colony by machine learning in which multiple types of index values are used. This makes it possible to accurately and non-invasively assess whether cells, or cells in a colony, are in an undifferentiated aberrant state.
