Gynecologic specimen analysis by multiangle light scattering in a flow system.

Abstract

A flow-system instrument is described in which the laser light scattered by a mammalian cell is sampled simultaneously at up to 32 angles between 0 degrees and 21 degrees from the laser beam axis as the cell passes through the beam. The scatter pattern for each cell is stored by a computer for later analysis. Various data-processing techniques are discussed. Results of preliminary application of the instrument to the analysis of normal and abnormal gynecologic specimens are presented.
