Abstract: An array of CMUT cells (10) has a DC bias voltage (VB) coupled to the membrane and floor electrodes of the cells to bias the electrode to a desired collapsed or partially collapsed state. The low voltage or ground terminal of the DC bias supply is coupled to the patient-facing membrane electrodes (20) and the high voltage is applied to the floor electrodes (22). An ASIC for controlling the CMUT array is located in the probe (100') with the array. The ASIC electronics are electrically floating relative to ground potential of the ultrasound system (150) to which the CMUT probe is connected. Control (82) and signal (84) lines are coupled to the CMUT probe by level shifters (90) which translate signals to the floating potential of the ASIC and provide DC isolation between the CMUT probe and the ultrasound system.

Abstract: An array of CMUT cells (10) has a DC bias voltage (VB) coupled to the top electrodes of the cells to bias the electrode to a desired collapsed or partially collapsed state. Fuses (200) are coupled in series with the bottom electrodes (22) of the cells which will open and isolate an individual cell from the other still-functional cells of the array in the event of a failure of the individual cell. In a preferred embodiment the cells are coupled to control integrated circuitry such as microbeamformer circuitry and the fuses are formed of semiconductor materials with the integrated circuitry, thereby leaving the MUT surface area available for high density MUT fabrication. Damage to the integrated circuitry due to short-circuiting of the DC bias current through a failed cell is prevented.

Abstract: Methods and devices are described for driving ferroelectric perovskite oxide crystals to achieve polarization inversion with reduced coercivity. In some embodiments, the anisotropy in the potential energy surface of a ferroelectric material is employed to drive polarization inversion and switching with a reduced coercive field relative to uniaxial excitation. In some embodiments, polarization inversion with reduced coercivity is produced via the application of an electric field that exhibits a time-dependent orientation, in contrast with conventional uniaxial electrical excitation, thereby causing the central ion (and the crystal structure as a whole) to evolve along a lower-energy path, in which the central ion is driven such that it avoids the potential energy maximum. This may be achieved, for example, by applying at least two non-parallel time-dependent voltages (e.g. bias, potential) such that orientation of the electric field changes with time during the switching cycle.

Abstract: An ultrasound generator comprising a signal generator and a transducer, and a method of generating ultrasound. The signal generator is arranged to receive, generate or calculate when instructed a modulating signal with a magnitude that varies within a first range, the signal generator is further arranged to generate a pulsed drive signal having a predefined first relationship to the modulating signal, the pulsed drive signal having at least a zero output level, a positive output level and a negative output level, wherein the position and width of pulses are defined by at least first and second switching angles per half cycle of the modulating signal. The transducer is arranged to generate ultrasound in response to the pulsed drive signal. The first relationship is selected such that within at least part of the range of magnitude of the modulating signal the first and second switching angles are adjusted simultaneously to provide for an increase or decrease in the magnitude of the fundamental frequency of the pulsed drive signal corresponding to an increase or decrease in the magnitude of the modulating signal. The first relationship is also selected such that a selected harmonic component of the generated pulsed drive signal is maintained below a first threshold.
