1. A method of reducing artifacts in an image due to an object, comprising:
accessing parameters of the object;
creating at least one forward projection of the object based on the accessed parameters;
registering the object in the forward projection to at least one acquired projection having the object therein;
modifying the at least one acquired projection to a representation of the registered object; and
generating a reconstruction based on the modified at least one acquired projection.
