Predicted performance of single- versus multiple-slit flow systems.
Flow systems utilizing multiple orthogonal excitation slits have been proposed as a means of reducing some types of false alarms in prescreening systems for gynecologic cytology. Such false alarms include those caused by orientation-dependent events, such as passage of binucleate or overlapping cells through the measurement region with both nuclei entering the excitation slit simultaneously. This paper presents distributions of optimal projection angles for randomly oriented nuclei passing through one, two, and three slit excitation regions. The results are used to compute observed nuclear spacing of binucleate cells and to compare performance of one, two, and three slit systems in recognition of binucleate and overlapping cells.
