Reconfigurable liquid attenuated collimator

A variably reconfigurable radiographic aperture mask collimator apparatus, the apparatus comprising:

• a grid manifold having an end cap and a plurality of passageways each having a cross sectional area and a length, wherein the plurality of passageways is disposed within the grid manifold, and wherein the end cap is fabricated from a material having a first attenuation value per unit volume;
• a plurality of conduits fluidically coupled to the plurality of passageways;
• a pumping system having a pump and a control logic, wherein the pumping system is fluidicically coupled to the plurality of conduits and configured to pump an attenuating liquid having a second attenuation value per unit volume into the plurality of conduits and the plurality of passageways;
• wherein the first attenuation value is less than the second attenuation value;
• wherein the attenuating liquid forms a column that substantially conforms to the cross sectional area of one of the plurality of passageways or a cooperating one of a plurality of conduits, and terminates at a position along the length of the one of the plurality of passageways or the cooperating one of a plurality of conduits;
• and
• wherein the attenuating liquid is present in the one of a plurality of passageways, and absent from a corresponding one of a plurality of conduits.
