  • a wall portion that supports sessile particles derived from the fluid;

    means for forming images of the sessile particles and particles suspended in the fluid adjacent the wall portion;

    means for producing data corresponding with the images of the sessile particles and suspended particles;

    means for processing data corresponding to the images of the sessile particles and the suspended particles, and for removing data corresponding to the suspended particles, and for producing an output data segment corresponding substantially exclusively to the sessile particles present in the images; and
