| Objective The new real-time location system based on Gamma scintigraphy is designed to satisfy the location research on micro-system in the gastrointestinal tract. Methods The medical images collected from emission computed tomography were post-processed to distill the useful information which could be helpful to obtain the motion track of the device. Results The structure and arithmetic of the micro-medical device location system was introduced in this paper, which was validated through model test and preclinical test. Conclusion The results of the experiment indicate that using such technique can solve the location problem properly. This processing method is of great academic and applied value. |
