Abstract: A microwave oscillator ultrasound receiver which includes one or more pressure sensitive microwave resonators having a perturbable resonant frequency; one or more signal generators operable to generate one or more microwave carrier signals; one or more detectors configured to detect at one or more of: an amplitude and phase modulation of the one or more carrier microwave signals corresponding to resonance perturbations; and a computer processing device arranged to analyze any of the following: amplitude and phase modulation, and measure, based on the amplitude and phase modulation, an ultrasound signal, so that the resonance perturbations arise in response to the ultrasound signal being received by the pressure sensitive microwave resonator, the ultrasound signal effecting pressure changes on the pressure sensitive microwave resonator and thereby perturbing the perturbable resonant frequency.

Abstract: A microwave oscillator ultrasound receiver is provided herein. The microwave oscillator ultrasound receiver may include: one or more pressure sensitive microwave resonators having a perturbable resonant frequency; one or more signal generators operable to generate one or more microwave carrier signals; one or more detectors configured to detect at least one of: an amplitude and phase modulation of the one or more carrier microwave signals corresponding to resonance perturbations; and a computer processing device arranged to analyse the at least one of: amplitude and phase modulation, and therefrom measure an ultrasound signal, wherein the resonance perturbations arise in response to the ultrasound signal being received by the pressure sensitive microwave resonator, the ultrasound signal effecting pressure changes on the pressure sensitive microwave resonator and thereby perturbing the perturbable resonant frequency.
