1. A method for automated imaging and evaluation of human embryos, oocytes, or pluripotent cells with an imaging system, the method comprising:
- receiving a multi-well culture dish comprising a plurality of micro-wells on a stage of the imaging system, wherein the plurality of micro-wells contain a plurality of human embryos or pluripotent cells, wherein the imaging system comprises-at least one time-lapse microscope inside a housing;
initializing the imaging system, wherein initializing the imaging system comprises;
generating an initial image of the multi-well culture dish with the imaging system;
detecting the presence of the multi-well culture dish on the stage of the imaging system;
generating an estimate of a position and an orientation of the plurality of micro-wells, wherein generating the estimate of the position and the orientation of the plurality of micro-wells comprises;
generating an initial estimate of micro-well position and orientation;
generating a refined estimate of micro-well position and orientation; and
determining the position and orientation of the micro-wells in a rotated coordinate system;
providing an alignment indication, wherein the alignment indication comprises a first indication if the multi-well culture dish is properly aligned and a second indication if the multi-well culture dish is improperly aligned;
automatically illuminating the multi-well culture dish with an illumination source of the at least one time-lapse microscope when the multi-well culture dish is properly aligned; and
automatically focusing the at least one time-lapse microscope configured to capture time-lapse images of the multi-well culture dish when the multi-well culture dish is properly aligned;
acquiring time-lapse images of the multi-well culture dish with a camera of the at least one time-lapse microscope; and
analyzing the time-lapse images of the multi-well culture dish to determine a development potential of at least one human embryo or pluripotent cell.

Abstract
Apparatuses, methods, and systems for the automated imaging and evaluation of human embryos, oocytes, or pluripotent cells are described. An apparatus and method for automated dish detection and well occupancy determination are described. In addition, a multi-well culture dish and an illumination assembly for bimodal imaging are described. These inventions find use at least in identifying or in facilitating identification of embryos and oocytes in vitro that are most useful in treating infertility in humans.
