Abstract

Arguments are given for the pressing need to measure the local passage velocity, especially in the small intestine. Current velocity measurement methods are reviewed and a new magnetic method is presented. First results of “in vitro” experiments yielded a spatial resolving power in the order of 1 cm in any direction and demonstrate the feasibility of automatically imaging the trace of a magnetic marker moving through the gut and to measuring its local velocity.
