Reconstruction of Nuclear images in Human Gastrointestinal Tract Using an Electronic Engineering-based Capsule

Noninvasive dynamic tracing is very important to the alimentary canal micro-drug delivering device. In this paper, based on analyzing the rules of emission computed tomography images, a novel method for dynamic tracing micro-drug delivering device in alimentary canal has been proposed. The basic principle of the method is that, when the micro-drug delivering device with a mount of radioactive elements being encapsulated pass through the gastrointestinal tract, the series of medical images were detected by single photon emission computed tomography (SPECT), then the location of micro-device could be deduced and dynamic 3D tracks can be achieved. Through the experiment in simulative intestinal, the proposed method can be used to tracing the radioactive elements.
