Coupling loop and method of positioning coupling loop
First Claim
Patent Images
1. A method of positioning a coupling loop relative to a sensor, comprising:
- positioning the coupling loop relative to the sensor so that a first area of a housing for the coupling loop is in a predetermined position with respect to the sensor; and
adjusting an angle of the coupling loop relative to the sensor until a predefined pattern is formed by markings on the sensor and markings on the housing,wherein a medical imaging technology is used for positioning the coupling loop and adjusting the angle of the coupling loop.

Abstract
A coupling loop or antenna is provided that can be used with a system that determines the resonant frequency of a sensor by adjusting the phase and frequency of an energizing signal until the frequency of the energizing signal matches the resonant frequency of the sensor. In one embodiment orientation features are provided for positioning the coupling loop relative to the sensor to maximize the coupling between the sensor and the coupling loop.
