Title:
センサ装置および外乱信号の補償方法
Document Type and Number:
Japanese Patent JP5717313
Kind Code:
B2
Abstract:
The device has an electrical sensor circuit for generating a sensor signal. An induction circuit is provided to induce a compensation signal e.g. voltage, during an operation of a magnetic resonance tomography by a time-varying magnetic field. A summing unit (16) combines the compensation signal with the sensor signal for generating an output signal. A preamplifier preamplifies the sensor signal and compensation signal. The induction circuit is provided with three inductance loops that are orthogonal to each other. An independent claim is also included for a method of compensating interference signals, which are induced by a time-varying magnetic field of a magnetic resonance tomography in a sensor circuit.
