摘要：
Systems and methods are described for determining an orientation and position of a capsule inserted into the body of a patient. A magnetic field is applied to an area of the patient where the capsule is located. Sensor data, including inertial data from an inertial sensor and magnetic field data indicative of the applied magnetic field as detected by at least one magnetic field sensor, is wirelessly received from the capsule. An orientation angle of the capsule is determined based at least in part on the inertial data. The magnetic field data is compared to known characteristics of the applied magnetic field and a location of the capsule is determined based on the comparison.
