Application of RSS output of a Radio Transceiver to 2D Tracking of Ingestible Capsules

Facilities for on-site drug delivery and the need for taking tissue/fluid samples within the human gastrointestinal (GI) tract are quite invaluable for diagnosing GI related diseases where diagnosis can only be made by taking a biopsy from the intestinal walls. Such biopsies have traditionally been preformed using custom endoscopes. To be effective in the above named tasks, the real-time location of telemetry capsules within the GI tract must be known with minimum error. Our Real time laboratory experimental results shows that the presented method can be adapted into medical equipments with a high degree of reliability
