Claim:
1. A wireless sensor array communication system comprising: a sensor array composed of a plurality of wireless sensors, each of the plurality of wireless sensors comprising a resonant circuit that is excited responsive to an RF pulse received by the wireless sensor such that the resonant circuit provides a resonant energy, with a characteristic of the resonant energy being proportional to a measurand monitored by the passive wireless sensor; and an interrogator system comprising: wherein each of the plurality of wireless sensors is configured such that a frequency and phase of the resonant energy provided by the resonant circuit therein, and included in the RF signal transmitted therefrom, is altered responsive to the generated magnetic field and the applied magnetic field gradients, the altered frequency and phase of the resonant energy being a function of a location of the respective wireless sensor within the magnetic field.
