Abstract
A method and system is provided for evaluating viability of oocytes and embryos comprising imaging an oocyte or embryo using motility contrast imaging; generating temporal contrast and spatial contrast data for the cells; generating a cell viability value as a function of the temporal and spatial contrast data; and comparing the cell viability value to a predetermined value indicative of a cell suitable for use in an in vitro fertilization program.
