Abstract: The system adjusts the phase of an ultrasound channel by removing sample clock voltage pulses from a rectangular electrical waveform that drives the transducer. Each channel's transducer applies or acts as a band-pass filter in the conversion of the electrical waveform to mechanical motion, generating an ultrasound sine wave. Removing clock voltage pulses from the electrical waveform can shift the phase of the ultrasound by an amount less than a sample clock period. The system focuses and directs the ultrasound during shooting at a specific angle by applying phase delays to successive channels. Removing sample clock voltage pulses allows the system to shoot at smaller angles and create a greater scan density and focal point density of imaging data and reduces the power. Partial sample clock voltage pulses may also be removed. If needed, the system can increase the power by adjusting the power supply voltages. The system can utilize a lower frequency clock generator lowering the power utilization.

Abstract: Apparatus for real-time execution of ultrasound system actions includes processor and memory to store instructions. Execution of the instructions causes processor to receive a task list including task actions that include next task action in task list. Next task action includes task instructions. Processor determines whether next task instruction in next task action is a timed instruction that includes a timestamp field having a time value indicating a time at which next task action is to be executed, and a hardware-enable field indicating hardware elements required to be available before execution of timed instruction. If next task instruction is not a timed instruction, processor may execute next task instruction. If next task instruction is timed instruction, processor determines whether time value has expired. If time value has expired, processor signals an error has occurred, and if time value has not expired, processor waits for time value. Other embodiments are described.

Abstract: In an ultrasound imaging system that applies a beamformer to received ultrasound signal samples to form one or more beams represented by arrays of beamformed samples, a method and an apparatus compress each array of beamformed samples independently of the other arrays to form compressed beams. A plurality of analog to digital converters sample multiple analog ultrasound signals produced by a transducer array to provide multiple streams of ultrasound signal samples to the beamformer. The compressed beams are transferred via a digital interface to a signal processor. At the signal processor, the compressed beams are decompressed to form decompressed beams. The signal processor further processes the decompressed beams for diagnostic imaging, such as for B-mode and Doppler imaging, and scan conversion to prepare the resulting ultrasound image for display. This abstract does not limit the scope of the invention as described in the claims.
