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.

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.
