This study presents the 3D tracking of fluorine labeled capsules through the human intestinal tract using a dual frequency excitation scheme with a temporal resolution of 255ms. Liquid fluorine markers were Hexafluorobenzene and Perfluoro-15-crown-5-ether and capsule filling was 65l each. The study was performed in five healthy volunteers on two study days. Initial results are shown regarding the temporal and structural behavior of the capsule passages through the digestive tract.
