  • Patent number: 10722209
    Abstract: An ultrasound system for identifying a vessel of a subject comprises: an ultrasound probe configured to simultaneously acquire a sequence of ultrasound blood flow data frames (such as a sequence of ultrasound Doppler data frames) and a sequence of ultrasound B-mode data frames of a region of interest including the vessel over a predetermined time period; a blood flow region selecting unit configured to select a blood flow region in the sequence of blood flow data frames; and a vessel segmenting unit configured to segment the vessel in at least one frame of the sequence of ultrasound B-mode data frames based on the selected blood flow region. Since there is no need to manually place any seed point for vessel segmentation any more, the user dependency is reduced and a fast measurement is made possible.

  • Publication number: 20200229798
    Abstract: An ultrasound system and method enable ultrasonic imaging by inexperienced personnel at the home of a patient under the guidance of a remotely located diagnostic imaging expert. Improper use of the scanning device is prevented by allowing the remotely located imaging expert to enable or disable the transmission of ultrasound energy by the ultrasound system. Other functions of the ultrasound system may also be controlled by the remotely located expert, such as determining whether acquired ultrasound images can be viewed locally on the ultrasound system.

  • Patent number: 10695078
    Abstract: An infusion system for sonothrombolysis treatment uses a syringe loaded with a microbubble solution and operated by a syringe pump to deliver the microbubble solution to a subject during sonothrombolysis treatment. To prevent the stratification of the microbubble solution in the barrel of the syringe during treatment, the barrel also contains a plurality of magnetic beads which are agitated into semi-random patterns of motion in the syringe chamber during the procedure. The magnetic beads are moved by magnetic attraction and repulsion from the moving magnets of a magnetic stirrer mounted in proximity to the syringe during treatment.

  • Patent number: 9643000
    Abstract: Bubble presence within a region is monitored to determine if a predetermined condition is met such as whether the presence is of sufficient magnitude, the bubbles being subject to energizing (240). In some embodiments, the energizing only occurs when time- wise preceded by the determination (S508, S510). The determining can include measuring a grayscale value (104), or assessing the energy carried by a frequency component of the echo signal, in the region in real time. The energizing may occur region-by-region, automatically and without need for user intervention, in a treatment pass (S428) over the regions. The regions (232) in the pass might be subject to respective instances of the energizing without intervening monitoring, or, in another embodiment, to both the determining and the responsive energizing. The determining can be subject to, automatically and without need for user intervention, interruption (S408) and concurrent switching to a next region.

  • Patent number: 9272231
    Abstract: A device degasses fluid in a circulation loop. The device includes a degassing chamber coupled inline with the circulation loop, where a vacuum within the degassing chamber draws out dissolved gas and water vapor from the fluid. The degassing chamber has an opening enabling gas and water vapor drawn out from the fluid, and condensation formed from the water vapor, to flow out as a result of gravitational pull. The device further includes a cooler coupled to the opening in the degassing chamber and a water trap coupled to the cooler. The cooler includes a heat exchanger configured to condense a remaining portion of the water vapor into liquid, where the condensation and liquid accumulate in the water trap. The degassing chamber, water trap and cooler are maintained under vacuum, where the degassing chamber is maintained under vacuum through the opening via the cooler and the water trap.

  • Publication number: 20140196607
    Abstract: In one variation, a temperature-maintenance device includes a heater (1016) and is placeable in a circulation loop of an ultrasound transducer coupling bolus (1076), for degassing circulating liquid of the loop and for operating the heater for performing temperature control of the liquid. A temperature setpoint, such as a normal body temperature, for the liquid at the bolus may be entered. A device, either open- or closed-looped with respect to fluid flow, may include, in some variations, a degassing chamber, a water trap (1012), and an intervening cooler, all vacuumized by a vacuum pump (1024). The chamber may be configured and aligned for letting condensation automatically drain out. The water trap may be emptied, automatically and without the need for user intervention, by a motorized trap emptier and/or be emptiable by the user.

  • Patent number: 7126614
    Abstract: A hardware-based circuitry for digital processing for color saturation control circuitry, brightness control circuitry, contrast control circuitry, and color hue control circuitry, some or all of which can be added to the luminance/chrominance (Y/C) signals to the red green blue (RGB) digital YCbCr-to-RGB conversion circuitry that is required by devices such as an LCoS display device. (these controls can also be used without the Y/C-to-RGB conversion surrounding. Important is the fact that the signals for control be in Y/C domain) A digital video signal from the source in the Y/C (luminance/chrominance) domain is fed into processing circuitry, where the C (chrominance) component is split into Cb and Cr subcomponents. Digital YCbCr-to-RGB conversion circuitry transforms the Y/C signals to RGB domain, required by, for example, the LCoS display device.

  • Patent number: 6721488
    Abstract: A system that utilizes a determined time between characteristics from content for subsequently identifying the content and/or the corresponding content review position in the time domain. The system utilizes a database of previously stored time between characteristics from known content for matching to the determined time between characteristics from the content source. The characteristics may correspond to video tape indexing data, keyframe data, audio characteristics, text occurrences, and/or other known characteristics from the content. When a match is found between the determined time between characteristics and the stored times between characteristics, the system identifies the content. If corresponding time domain data is stored in the database, the system identifies the current content review position in the time domain.
