A HEAD PHANTOM FOR SIMULATING THE PATIENT RESPONSE TO MAGNETIC STIMULATION

摘要

A simulated body part (e.g., head phantom) containing one or more sensors detects the time changing electric and magnetic fields created by a magnetic stimulation device and applied to the simulated body part. The sensors are connected to electronics that determine if the sensor output evidences that the strength of the applied magnetic field is sufficient to stimulate the patient. The measured signal levels may be varied to simulate patients with different thresholds and sensory feedback may be provided to the operator to indicate the accuracy of the positioning and orientation of the stimulation coil. The electronics may further include an analysis device that determines if the magnitude and duration of the stimulation is sufficient to stimulate the target nerves. The phantom or coil positioning apparatus also measures the location and orientation of the coil so that the trainee's positioning can be measured against a known result. A head phantom embodiment may also provide additional features such as the ability to adjust the Motor Threshold (MT) or sensor locations.
