Research ultrasound technology developer Verasonics has netted six new patents since February.
The new patents include the following:
- People's Republic of China Patent No. ZL201811519036.5: "Method and System for Arbitrary Waveform Generation Using a Tri-State Transmit Pulser." This patent covers the company's design for arbitrary waveform generation using programmable duty cycle controls.
- Canadian Patent No. 2728998 and U.S. Patent No. 10914826: "High Frame Rate Quantitative Doppler Flow Imaging Using Unfocused Transmit Beams." This patent covers high-frame-rate Doppler sensing with long ensembles and unfocused beams, a feature that's used for microvascular and functional imaging, spectral Doppler over the full imaging field of view, and derived blood velocity parameter imaging, according to the vendor.
- Japanese patent No. 6952023: "Method and System for Coded Excitation Imaging by Impulse Response Estimation and Retrospective Acquisition." Enabling high-frame-rate synthetic aperture imaging with coded transmit waveforms from each element, this patent covers the design for generating arbitrary transmit waveforms using knowledge of the transducer impulse response, Verasonics said.
- Canadian Patent No. 2728998 and U.S. Patent No. 10914826: "Estimation and Display for Vector Doppler Imaging Using Plane Wave Transmissions." This patent covers vector Doppler imaging, as well as a new method of display using particle flows that enable flow direction to be visualized, according to the firm.
With these new patents, Verasonics now has 74 patents worldwide.
