Abstract
A wireless magnetic resonance imaging scanner has one or more local coils, a microwave antenna array, and a local oscillator, and an upconverter. The local oscillator signal from the local oscillator is transmitted from the microwave antenna array to illuminate the local coils. The local coils generate magnetic resonance signals at a first frequency and the magnetic resonance signals at the first frequency are upconverted in the upconverter to microwave frequencies. The local oscillator operates at a frequency within an unlicensed band, chosen such that desired sidebands for reception of the upconverted local coil magnetic resonance signals fall outside the unlicensed band.
