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.
![Examples of ultrasound findings and techniques. (A) Images in a 39-year-old male patient with a mass in the left thigh. The mass is heterogeneous on the B-mode US image (compared with the patient in D) and showed increased microvascularity (superb microvascular imaging [SMI]) and shear-wave elastography (SWE) values. Undifferentiated pleomorphic sarcoma was diagnosed at biopsy (with pleomorphic rhabdomyosarcoma in surgical specimen). (B) Images in an 18-year-old male patient with a mass in the left leg. The mass is hypoechoic on the B-mode image, with no other findings suggestive of malignancy. The lesion is in contact with the cortex of the tibia, which is slightly irregular. CT revealed a doubtful anteromedial tibial erosion. The microvascular study demonstrated high vascularization, suggestive of malignancy. Periosteal Ewing sarcoma was diagnosed with both histologic and immunohistochemical confirmation. (C) Images in a 69-year-old female patient with a lump growing on the outside of the left leg. Multiple SWE examinations were performed (please note the high values obtained in the measurements, whereas the color map highlights the stiffness relative to adjacent tissues). SMI showed areas of increased vascularization to target for sampling. Undifferentiated spindle cell sarcoma was diagnosed at biopsy, with residual leiomyosarcoma in the surgical specimen after neoadjuvant therapy. (D) Images in a 56-year-old female patient with a mass in the right thigh. The mass is heterogeneous at both B-mode ultrasound (similar to patient A) and MRI (coronal T2-weighted spectral attenuated inversion recovery [SPAIR]; T1-weighted pre-contrast and postcontrast imaging), which even shows uptake after the administration of paramagnetic contrast material, which is traditionally suggestive of malignancy. Low values at SMI and elastography are suggestive of benignity. Spindle cell lipoma was diagnosed at biopsy, with atypical spindle cell lipomatous tumor in the surgical specimen.](https://img.auntminnie.com/mindful/smg/workspaces/default/uploads/2026/08/images-radiol250278fig2.APCFLSvX6p.jpg?auto=format%2Ccompress&dpr=2&fit=crop&h=167&q=70&w=250)
