TDS-B1: Magnitude and Polarization Measurement in MRI Coil

Our latest video demonstrates ZMT's TDS-B1 to measure the polarization of the MITS3.0 birdcage resonator quickly and precisely. Two orthogonal time domain sensor (TDS) probes from our Z43 partner company SPEAG convert the incident radiofrequency magnetic field signals from the MITS to an optical signal, which is fiber-optically transmitted and opto-electrically converted by the remote units, captured by an oscilloscope, and transmitted to the computer where the polarization is computed and displayed. The full pulse train can also be seen in the time-domain view.

The TDS magnetic field probes can be used in free space or in loaded phantoms to measure the incident fields accurately in frequency or time domain, and they can operate inside harsh electromagnetic environments such as during magnetic resonance imaging scans.
