Abstract:
A method for duplicating an imaged field of view in a biological fluid sample, which sample is contained in a chamber, said method comprising:a) providing the sample on a hydrogel in the chamber; b) providing a plurality of stationary distinguishable formed bodies on a surface of the hydrogel; c) forming an image of a first field of view of the sample in the chamber, said image including a position pattern of said stationary formed bodies in said first field of view image; d) recording an X, Y grid location of said first field of view image in the chamber; e) moving away from said first field of view image; f) returning to said recorded X, Y grid location of said first field of view image; g) re-imaging said first field of view after returning thereto; h) comparing the positions of said stationary formed bodies in the first field of view images obtained in steps c) and g); and i) superimposing the stationary formed body positions in the re-imaged first field of view on the recorded position pattern of the stationary formed body positions from the first field of view so as to duplicate said first imaged field of view in said re-imaged field of view.
