Cellular vitality of organoids is evaluated by AI-assisted algorithm. (A) Light field images of active organoids and aging organoids are evaluated by AI algorithm. The corresponding organoids are marked by boxes; (B) Output parameters include organoid number and organoid average diameter; (C) As to viability evaluation of organoids, the active organoids and aging organoids can be marked by boxes on the output images; (D) Output parameters include the proportion of active organoids and aging organoids.
