Abstract
A method, system and apparatus for selecting cells is disclosed. An example embodiment provides spatial information denoting the location, on a four part array of sensors, referred to as a quad array, of the center, of each particle that passes through the focused laser beam in a cell sorter. The center of a particle is commonly determined by the average fluorescence intensity within the field of view of a Side Fluorescence (SFL) collection lens. Fluorescence collected by an SFL lens from a particle having any orientation and any position in the core stream produces a spot large enough to illuminate all four segments of a quad array. By independently measuring the fluorescence intensity recorded by each of the four array segments for a particle, it is possible to calculate the x-y coordinate position across the quad array segments of the average total fluorescence emission collected from that particle.
