Abstract: Ultrasound signal processing circuitry and related apparatus and methods are described. Signal samples received from an ultrasound transducer array in an ultrasound transducer based imaging system may be processed, or conditioned, by application of one or more weighting functions. In some embodiments, one or more weighting functions may be applied to the signal samples in the time domain. In other embodiments, the signal samples may be converted to the frequency domain and one or more weighting functions may be applied in the frequency domain. In further embodiments, one or more weighting functions may be applied in the time domain and one or more weighting functions may be applied in the frequency domain. The weighting functions may be channel dependent and/or channel independent. The processed data can be provided to an image formation processor.

Abstract: A variable current trans-impedance amplifier (TIA) for an ultrasound device is described. The TIA may be coupled to an ultrasonic transducer to amplify an output signal of the ultrasonic transducer representing an ultrasound signal received by the ultrasonic transducer. During acquisition of the ultrasound signal by the ultrasonic transducer, one or more current sources in the TIA may be varied.

Abstract: To implement a single-chip ultrasonic imaging solution, on-chip signal processing may be employed in the receive signal path to reduce data bandwidth and a high-speed serial data module may be used to move data for all received channels off-chip as digital data stream. The digitization of received signals on-chip allows advanced digital signal processing to be performed on-chip, and thus permits the full integration of an entire ultrasonic imaging system on a single semiconductor substrate. Various novel waveform generation techniques, transducer configuration and biasing methodologies, etc., are likewise disclosed. HIFU methods may additionally or alternatively be employed as a component of the "ultrasound- on- a-chip" solution disclosed herein.

Abstract: Programmable ultrasound probes and methods of operation are described. The ultrasound probe may include memory storing parameter data and may also include a parameter loader which loads the parameter data into programmable circuitry of the ultrasound probe. In some instances, the ultrasound probe may include circuitry grouped into modules which may be repeatable and which may be coupled together to allow data to be exchanged between the modules.

The digitization of received signals on-chip allows advanced digital signal processing to be performed on-chip, and thus permits the full integration of an entire ultrasonic imaging system on a single semiconductor substrate. The on-chip digitization of received signals also enables the on-chip integration of ultrasound processing and/or pre-processing to reduce the burden on off-chip computing. Data compression architectures are disclosed to facilitate the transfer of data off-chip as a digital data stream in accordance with the bandwidth requirements of standard commercially- available output interfaces.
