Cell lineage extracting method
First Claim
1. A method for constructing a cell lineage comprising the steps of:
- (a) obtaining a plurality of 2D images different in focal plane and time by taking a plurality of 2D images changing the focal plane and taking a plurality of 2D images in a time series for a cell constituting the subject of observation;
(b) extracting a nucleus area by carrying out image processing for individual 2D images;
(c) unifying the nucleus area extracted from the individual 2D images, which is derived from an identical nucleus; and
(d) constructing the cell lineage from a time and a position, where the nucleus area emerges and disappears in the image, in the unified nucleus area.

Abstract
The present invention provides a method for constructing cell lineage that is less labor intensive and requires less time as a result of using a computer. The method comprises the step for obtaining a plurality of 2D images different in focal plane and a time by taking a plurality of the 2D images by changing the focal plane and taking a plurality of the 2D images in a time series for a cell constituting the subject of observation. The method further comprises the steps of extracting a nucleus area by carrying out image processing for individual 2D images; unifying the nucleus area, which is derived from the identical nucleus, from the nucleus area extracted from the individual 2D images; and constructing the cell lineage from a time and a position, where the nucleus area appears and disappears in the image, in the unified nucleus area.

wherein(e) said step (b) comprises the steps of;
extracting the area to become a candidate of the nucleus;
designating a presumable nucleus area by a trial operation of cell lineage preparation; and
extracting the nucleus area by feedback of the presumable area to the nucleus candidate area. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22)
