Abstract: In one embodiment of the invention, there is an ultrasound processing system that communicates images over a single asynchronous serial channel according to a scheme that does not require an isochronous serial channel and that switches among ultrasound imaging modes robustly. For example, the system is configured to packetize ultrasound image data of at least one ultrasound imaging mode into a stream of data frames and to convey the stream of data frames via the asynchronous channel. Each data frame includes indication of the ultrasound imaging mode and includes ultrasound-imaging-mode-specific imaging parameters. Other embodiments exist.

Abstract: An ultrasound information processing system comprises a plurality of ultrasound devices coupled to a high-speed serial ultrasound information bus, wherein each ultrasound device comprises a program for communicating with other ultrasound devices according to an ultrasound information exchange protocol (UIEP). The UIEP is a lightweight, connection-oriented protocol adapted to efficiently transfer ultrasound information among different devices on the ultrasound information bus. Each ultrasound device comprises an application layer program for performing an ultrasound function, as well as a lower protocol layer program for receiving and sending data across the ultrasound information bus according to a high-speed serial bus standard that provides both isochronous and asynchronous data delivery. The ultrasound information exchange protocol (UIEP) program is adapted to receive a communication request from the application layer, open a connection-oriented communication session with the requested ultrasound device, and transfer ultrasound information through the lower protocol layer and across the ultrasound information bus to the requested device. Advantageously, any ultrasound device manufacturer provided with the UIEP program may readily generate application layer code capable of communicating with other manufacturers' ultrasound devices across the ultrasound information bus, without requiring specific knowledge of the internal structure of the other manufacturers' devices or of the specific frame/packet structure of the UIEP/lower layer protocols themselves.

Abstract: An ultrasound imaging system capable of generating a flow image from B-mode echo frames. For each location in a target region, phase information is derived from the B-mode echo frames, and frame-to-frame changes in the phase information are processed to detect the presence of fluid flow at that location. A demodulator receives the B-mode echo frames and demodulates them into baseband signal components from which the phase information is derived. Preferably, the demodulator is highly accurate and robust, such that frame-to-frame changes in the phase information are reliably measured. From the reliably measured phase information, a phase shift metric is then computed and thresholded by a user-adjustable threshold value. Flow is present if the phase shift metric is greater than the threshold value and is absent otherwise. The user may adjust the threshold value in real time through an input device, such as a knob or keyboard, to increase or decrease the flow sensitivity as desired and/or to eliminate the slow-moving clutter. Together with a B-mode image, the flow image is provided to an ultrasound display. For further clutter removal, the flow image may be suppressed for those locations having B-mode intensities below a predetermined lower threshold or above a predetermined upper threshold. The provided system provides a real-time flow image having the same high frame rate, spatial resolution, and coverage area as the B-mode image.
