  • Patent number: 10667831
    Abstract: Disclosed herein are ultrasonic probes and systems incorporating the probes. The probes are configured to produce an ultrasonic therapy exposure that, when applied to a kidney stone, will exert an acoustic radiation force sufficient to produce ultrasonic propulsion. Unlike previous probes configured to produce ultrasonic propulsion, however, the disclosed probes are engineered to produce a relatively large (both wide and long) therapy region effective to produce ultrasonic propulsion. This large therapy region allows the probe to move a plurality of kidney stones (or fragments from lithotripsy) in parallel, thereby providing the user the ability to clear several stones from an area simultaneously. This “broadly focused” probe is, in certain embodiments, combined in a single handheld unit with a typical ultrasound imaging probe to produce real-time imaging. Methods of using the probes and systems to move kidney stones are also provided.

  • Publication number: 20190314045
    Abstract: Targeting methods and devices for non-invasive therapy delivery are disclosed. In one embodiment, a method for targeting an object in a body using ultrasound includes: producing a therapy ultrasound waveform configured to fragment or comminute the object in the body using a therapy transducer of an ultrasound probe; and acquiring a sound waveform by a receiver. The sound waveform is at least in part caused by interactions of the therapy ultrasound with the object. The method also includes generating an indication of a targeting accuracy based on the acquired sound waveform.

  • Publication number: 20150320383
    Abstract: A system and method for determining, via ultrasound, a size of a concretion in a subject are provided. One or more ultrasound pulses are transmitted into a tissue in the subject, which are then reflected from the tissue and received by the ultrasound transducer. A shadow region obscured by the concretion that does not provide reflected signals is generated, and the width of the shadow region is measured. The width of the object is determined based on the width of the shadow region.

  • Publication number: 20150320384
    Abstract: A system and method for detecting, via ultrasound, a concretion in a subject are provided. One or more ultrasound pulses are transmitted into the concretion and at least one object of interest, such as a bubble, present in the concretion. Reflection signals from the concretion and the bubble are then contrasted using the twinkling artifact, and a filter removes motion signals. An output device, such as a display, provides an indication of the presence of the concretion based on the reflection signals.

  • Patent number: 9005126
    Abstract: Tissue Pulsatility Imaging (TPI) is an ultrasonic technique developed to measure tissue displacement or strain in the brain due to blood flow over the cardiac and respiratory cycles. Such measurements can be used to facilitate the mapping of brain function as well as to monitor cerebral vasoreactivity. Significantly, because tissue scatters ultrasound to a greater extend than does blood, using ultrasound to measure tissue displacement or strain in the brain is easier to implement than using ultrasound to measure blood flow in the brain. Significantly, transcranial Doppler sonography (TCD) has been used to measure blood flow in the brain to map brain function and monitor cerebral vasoreactivity; however, TCD can only acquire data through the three acoustic windows in the skull, limiting the usefulness of TCD. TPI is not so limited.
