Non-invasive medical procedures are desired in modern medicine because of advantages they provide in patients safety and comfort. A cutting edge non-invasive medical procedure implemented specifically for cancer treatment is proton emission therapy. However, to safely implement this procedure on the thorax or abdomen, it is important to monitor heartbeat and respiration since they displace surrounding tissue. Conventional methods for measuring patient’s vital signs are problematic because metal wires or leads of these systems interfere with the proton beam. These metal leads and wires deflect the proton beam, become radioactive as they are bombarded with radiation, and become entangles with other equipment as the procedure is conducted. This thesis documents research investigating the feasibility of implementing a non-intrusive microwave radar system for monitoring a patient’s chest displacement from breathing and heart motion. Investigation into first steps toward building a standalone prototype are also investigated.
