Various methods and systems for positioning microspheres for imaging are provided. One system includes a filter medium that includes openings. The openings are spaced in a substantially equidistant manner across the filter medium. The system also includes a flow subsystem coupled to the filter medium. The flow subsystem is configured to exert a force on the microspheres such that the microspheres are positioned above the openings. A method for positioning microspheres for imaging includes exerting a force on the microspheres through a filter medium such that the microspheres are positioned above openings in the filter medium. The openings are spaced as described above.
