Abstract: A method and system for modeling growth of reductant deposits for an aftertreatment system on a real time basis using input including exhaust gas temperature, exhaust gas flow rate, and reductant dosing rate. The growth of the reductant deposits are affected by a rate at which reductant accumulates and decomposes from a surface of the aftertreatment system. Thus, the method and system disclosed determines a net reductant deposit growth rate value based on a reductant deposit accumulation rate value and a reductant deposit decomposition rate value. Further, the method and system disclosed determines a reductant mass deposit value based on the net reductant deposit growth rate value. The reductant mass deposit value determined by the method and system may then be used to control a regeneration strategy of the aftertreatment system to eliminate the reductant deposits from the aftertreatment system.

Abstract: Techniques for suppression of motion artifacts in medical imaging include obtaining projections at different times within a time interval from a medical imaging system operating on a subject. A stationary projection is determined for a first subset of the projections in which a signal source and detector array of the imaging system are in a first configuration relative to the subject. An image of the subject based on the stationary projection is displayed. For any subset, the stationary projection is a minimum value for each pixel among the subset of projections if a signal passing through a moving object of interest inside the subject is expected to cause an increase in a pixel value. Alternatively, the stationary projection is a maximum value for each pixel among the subset of projections if the signal passing through the object of interest is expected to cause a decrease in a pixel value.
