Title: Innovations of Steven Russell Freeman
Introduction
Steven Russell Freeman is an accomplished inventor based in Seattle, WA. He holds a total of 12 patents that showcase his expertise in ultrasound technology and signal processing. His innovative contributions have significantly advanced the field of medical imaging.
Latest Patents
Among his latest patents is a system and method for dynamic filtering. This invention involves processing an analog waveform before it is sampled by an analog-to-digital converter (ADC) for multiline beamforming in ultrasound systems. The method enables multiline beamforming by delaying the same waveform by two different time delays and re-combining the delayed waveforms. This architecture can also be utilized for temporal filtering, allowing a single acoustic signal to be read out of the ARAM twice, separated by time, leveraging non-destructive read operations.
Another notable patent is the ultrasound imaging system with transmit apodization. This digital transmit beamformer features a waveform sample memory that stores sequences of samples of different pulse transmit waveforms with varying pulse widths. The memory is shared among multiple transmit channels, allowing each channel to access its selected sample sequence independently. During a transmit event, the waveform sample readout occurs simultaneously across channels, producing a transmit beam with different pulse waveforms applied to various elements of the transmit aperture.
Career Highlights
Steven has worked with renowned companies such as Koninklijke Philips Corporation N.V. and Koninklijke Philips Electronics N.V. His experience in these organizations has contributed to his development as a leading inventor in the field of ultrasound technology.
