摘要：
A tool dislodgement detection apparatus 10 includes and MPS 20 outputting position and orientation (P&O) readings for determining tool 26 motion. A control 12 generates an alarm based on the tool motion and dislodgement 2 criteria. The criteria includes whether the tool motion meets a condition based on the type of medical procedure or tool, the tool parking position, a patient characteristic (.e.g., age, weight, gender) or a physician preference. The criteria includes when the correlation between the tool motion and the cardiac, respiration and patient motion changes abruptly. In a prolapse detection apparatus, guidewire tip P&O readings determine a tip 68 motion vector 70. The control generates an alarm using the motion vector and predetermined criteria. The criteria include a substantial change in the tip orientation not accompanied by a corresponding position change and a change in the motion vector by about 180° accompanied by a corresponding position change no greater than a threshold.
