Method for detecting a cell event

A method for detecting or predicting the occurrence of a cell event, selected from between cell division or cell death, in a sample, the sample extending in at least one sample plane and comprising cells immersed in a medium, the method comprising:

• a) arranging the sample between a light source and an image sensor;
• b) illuminating the sample using the light source and acquiring a plurality of successive images of the sample using the image sensor, at different instants forming an acquisition time range, each image being representative of an exposure light wave to which the image sensor is exposed;
• c) on the basis of each acquired image of the sample, calculating an observation image at each instant, the observation image corresponding to a spatial distribution:
• of an optical path difference induced by the cells, the optical path difference at each transverse coordinate corresponding to a difference between the optical path of the exposure light wave respectively in the presence and in the absence of a cell at the said transverse coordinate
• or of an absorbance of the cells, in the sample plane;
• wherein the metho further comprises:
• d) using the observation images resulting from c) as input data of a supervised artificial intelligence algorithm, so as
• to detect and locate an occurrence of the cell event during the acquisition time range;
• or to predict an occurrence and a location of the cell event subsequent to the acquisition time range.
