1. Apparatus for processing blood which has pathogen cells therein, comprising:
a chamber having an input port for receiving said blood and an output port for evacuating said blood from said chamber, said chamber having opposing transparent walls,
a light source for producing collimated light that is directed through said chamber,
an image sensor having an array of pixels, said image sensor positioned to receive light that has passed through said walls of said chamber from said light source, said image sensor producing a sensor image of said received light, said sensor image having therein shadow images of cells in said blood,
an electronic storage for storing reference images of said pathogen cells therein,
a pattern recognition processor coupled to receive said sensor image from said image sensor and said reference cell images for identifying ones of said shadow images which at least partially compare to one of said reference cell images, said processor for further determining the locations in said chamber for said ones of said shadow images which at least partially compare to one of said reference cell images, and
a first plurality of parallel electrical conductors adjacent a first of said walls of said chamber and a second plurality of parallel electrical conductors adjacent a second of said walls of said chamber, said first plurality of parallel electrical conductors substantially perpendicular to said second plurality of parallel electrical conductors, and
first and a second driver circuits coupled respectively to said first and second plurality of parallel electrical conductors for applying a voltage differential selectively to pairs of said electrodes, one electrode of each said pair being a conductor in said first plurality of parallel electrical conductors and a second conductor of each said pair being a conductor in said second plurality of parallel electrical conductors.
