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 ex periment in simulative intestinal, the proposed method can be used to tracing the radioactive elements.
