Abstract
A method of re-locating an object in a sample is provided for a previously-scanned slide having determined objects each with corresponding stored coordinates and a stored image, the objects being mapped relative to each other. The slide is positioned on a microscope stage, stored images of the objects are visually displayed, and a target object is selected. The slide is moved to an estimated coordinate position, corresponding to the coordinates of the target object, and a field-of-view image of the sample is captured for comparison to the stored image of the target. If the target is in the image, an offset between actual coordinates of the located target and the stored coordinates of the corresponding object is determined. The slide is then moved, via the stage, from the estimated coordinate position, according to the offset, to center the target in the image. Associated systems and methods are also provided.
