1. A method for identifying a specific cell as being of a known cell type, wherein the known cell type relates to the viability of the cell, comprising:
- staining a nucleus of the specific cell with a fluorescence stain;
directing incident light at the specific cell to obtain a nuclear image and a brightfield image of the specific cell with a light detector; and
determining the known cell type to which the specific cell corresponds, based on morphologic features of the specific cell that are derived from the nuclear image and the brightfield image, wherein the morphologic features include at least one morphologic feature selected from the group consisting of a size of the specific cell, a size of a nucleus in the specific cell, and a brightfield image contrast of the specific cell.

Abstract
Provided are methods for determining and analyzing photometric and morphometric features of small objects, such as cells to, for example, identify different cell states. In particularly, methods are provided for identifying apoptotic cells, and for distinguishing between cells undergoing apoptosis versus necrosis.

9. A method for identifying a specific cell, to enable a determination to be made as to whether the specific cell corresponds to a known cell type, wherein the known cell type relates to the viability of the cell, comprising:
-
directing incident light at the specific cell and using a detector to image the specific cell; calculating a contrast metric for a brightfield image of the specific cell; determining a nuclear size for the specific cell from nuclear imagery of the specific cell; and based upon the contrast metric for the brightfield image and on the nuclear size of the specific cell, determining if the specific cell corresponds to the known cell type. - View Dependent Claims (10, 11, 12, 13, 14, 15)
