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.
