Abstract:
1. A wireless magnetic resonance imaging data acquisition device, comprising: Radio Frequency (RF) local coils and gradient coils operable to obtain magnetic resonance data from a subject, a microwave antenna array, a local oscillator, and an upconverter; said local oscillator supplying a local oscillator signal from the microwave antenna array in order to operate the local coils; said local coils generating said magnetic resonance signals at a first frequency, and said upconverter upconverting said magnetic resonance signals at said first frequency into microwave frequencies; and said local oscillator emitting a local oscillator frequency in the 2.4 GHz Industrial, Scientific, and Medical (ISM) band in order to cause desired sidebands for reception of the upconverted local coil magnetic resonance signals to be located outside of said ISM band.
