Paper Abstract

Recent advances in autofocus, image segmentation, and fluorescence lamp stabilization have resulted in a fully automated high-speed image cytometer. This system performs computer-controlled autofocus, incremental stage scanning, image processing and data storage at a combined 1 Hz field rate. DAPI stained 3T3 cells that were cultured on microscope cover slips were scanned using the scanning cytometer. The integrated intensity for each detected cell object was computed and stored as well as its area and information about its location. Performance of the system was evaluated by repeatedly scanning cellular objects and comparing the results of each object over several hundred scans. This method of performance evaluation has the advantage of being independent of variations in stain homogeneity of the slide being scanned. For several hundred repeat scans, coefficients of variation (CVs) of significantly less than 1% were consistently obtained for the integrated intensity of each cellular object in the experiment.
