Published Workflows
Objective: Enable fast high-resolution volumetric ultrasound imaging for large-field 3D mapping of human tissue compartments and vasculature.
Why it works: The abstract states that challenges in high-resolution human imaging can be addressed with a large transducer aperture and fast acquisition and processing, and that programmable ultrafast ultrasound scanners with a high channel count provide an opportunity to optimize volumetric acquisition.

The approach requires a large transducer aperture, fast acquisition and processing, and programmable ultrafast ultrasound scanners with a high channel count. The reported implementation used a 47-centimeter aperture.; requires a large transducer aperture; requires fast acquisition and processing; benefits from programmable ultrafast ultrasound scanners with a high channel count
The abstract notes that subtle motion and the presence of bone or gas are challenges for high-resolution human imaging, rather than claiming these are universally eliminated. No claim is made that the method solves all such imaging obstacles in every setting.; high-resolution human imaging is challenged by subtle motion and the presence of bone or gas

Inferred from claim c3 during normalization. A large volume scan of a human limb was completed in a few seconds and enabled three-dimensional reconstruction of vasculature with about 50 decibels of vessel-to-tissue image intensity difference in a 2-millimeter dorsal vein. Derived from claim c3. Quoted text: A large volume scan of a human limb is completed in a few seconds, and in a 2-millimeter dorsal vein, the image intensity difference between the vessel center and surrounding tissue was ~50 decibels, facilitating three-dimensional reconstruction of the vasculature.
