Latest Patents

One of his notable patents is for a "Three-dimensional fly-through systems and methods using ultrasound data." This innovation allows for the representation of a volume using high spatial resolution ultrasound data. By modulating B-mode data with Doppler or flow information, the spatial resolution or contrast of the B-mode data may be enhanced. The same set of ultrasound data is utilized for identifying a boundary, placing the perspective position within the volume, and rendering from that perspective. The identification of the boundary and rendering can be automated or performed by a processor. This technology enables the generation of three-dimensional fly-through representations, facilitating virtual endoscopy and other diagnostically useful views of structures or fluid flow channels. The virtual processes are non-invasive, enhancing patient comfort and offering selectable depths of focus. They may also allow for fly-through of various types of anatomy and serve as a training tool.

Another significant patent is for a "Multifrequency ultrasonic transducer for 1.5D imaging." This invention features an ultrasonic transducer with a center row of transducers operating at a center frequency, along with first and second outer rows of transducers that may operate at a common frequency or different frequencies lower than the center frequency. The enhancement of the ultrasonic transducer array includes a matching layer with an acoustic velocity that is higher than those associated with the outer row transducers. This design allows for high-resolution near-field imaging while improving far-field imaging without the need for a 2D transducer array.
