Abstract
An imaging system includes transmit circuitry, a transducer array with an array of capacitive micromachined ultrasonic transducer elements, a beamformer, a decoder and a display. The transmit circuitry includes a signal generator and at least one excitation coding scheme. The transmit circuitry combines an excitation signal generated by the signal generator with an excitation coding scheme of the at least one excitation coding scheme, generating a coded excitation signal. The array of transducer elements is excited with the coded excitation signal to emit ultrasound signals. The coding scheme does not introduce heating on the capacitive micromachined ultrasonic transducer elements. The array of ultrasonic transducer elements receives echo signals produced in response to the ultrasound signals interacting with structure and generates electrical signals indicative thereof. The beamformer beamforms the electrical signals, the decoder removes the coding from the beamformed signals, and the display displays an image with the decoded signals.
