    Abstract: An intraoperative probe and a system for optically imaging a surgically significant volume of tissue or other scattering medium. An illumination source generates an illuminating beam that is conveyed to the vicinity of the tissue and a beam splitter, that may be no more than an optical phase reference, splits the illuminating beam into a sample beam along a sample beam path and a reference beam along a reference beam path. A scanning mechanism scans a portion of the sample beam across a section of the scattering medium, while a detector detects return beams from both the reference beam path and the sample beam path and generates an interference signal. A processor computationally moves an effective focus of the sample beam without physical variation of focus of the sample beam. The probe may have a sterilizable fairing that may be detachable.

  • Patent number: 9198635
    Abstract: High intensity ultrasound (HIU) is used to facilitate surgical procedures, such as a laparoscopic partial nephrectomy, with minimal bleeding. An apparatus is configured to emit HIU from one or more transducers that are attached to a minimally invasive surgical instrument. Such a tool preferably can provide sufficient clamping pressure to collapse blood vessels' walls, so that they will be sealed by the application of the HIU, and by the resulting thermal ablation and tissue cauterization. Such an instrument can provide feedback to the user that the lesion is completely transmural and that blood flow to the region distal of the line of thermal ablation has ceased. Similar instruments having opposed arms can be configured for use in conventional surgical applications as well. Instruments can be implemented with transducers on only one arm, and an ultrasound reflective material disposed on the other arm.

  • Patent number: 9182260
    Abstract: The invention relates to an ultrasonic flow meter arranged to measure a flow rate of a liquid, the flow meter comprises a flow tube 2, optionally a measurement insert, and two or more ultrasonic transducers 8 which are arranged in transducer inserts 20 to be inserted into the flow tube through openings in the flow tube. The transducer inserts are formed monolithically with the housing as a part of the bottom of the housing. The transducer inserts are in a mount position inserted through the openings in the flow tube to extend into the flow passage so that the surface 15 of the transducer inserts protrude into the flow passage. In this manner, gas bubbles, such as air bubbles, released from the flowing liquid will not rest in front of the transducer insert irrespectively of the orientation of the flow meter in the pipe installation.

  • Patent number: 9126177
    Abstract: Methods and systems for acoustically treating material using a continuous process in which material may be caused to flow in a continuous or intermittent fashion into/out of an acoustic treatment chamber where the material is exposed to focused acoustic energy. The methods and systems may be arranged to permit continuous processing for extended periods while an acoustic energy source operates at a relatively high power output. Treatment chambers may include features such as an acoustic window, a heat exchanger, inlet/outlet flow arrangements, an inspection window, insert elements that define a treatment volume size or shape, etc. Treatment system configurations relating to arrangements of a treatment chamber relative to an acoustic source and coupling medium, material flow paths, and others are provided.

  • Patent number: 9066679
    Abstract: A real-time signal processing technique for ultrasonic imaging of tissue vibrations for localizing the source of a bruit in a 2D image with respect to the anatomy and/or for obtaining simultaneous information about vibrations and the underlying blood flow. The bruit can be quantitatively assessed using an ensemble of ultrasound echoes. Signal processing enables estimation of wall displacement and the display of time-resolved vibration spectrum. Vibrations are detected and color-coded according to their amplitude and frequency and overlaid on the B-mode and/or color-flow image in real time. Proposed vibration imaging algorithms use data acquired during conventional ultrasonic color-flow imaging and the clutter signal, normally suppressed in color-flow imaging, to detect and characterize tissue vibrations. Three vibration imaging algorithms based on parametric modeling of vibrations and other criteria distinguish between clutter, blood flow, and vibrations.

  • Publication number: 20150135840
    Abstract: Methods and systems for coupling ultrasound to the body, including to the head, are disclosed. The system is optionally configured to transmit ultrasound energy for transcranial ultrasound neuromodulation. Couplant assemblies are described that incorporate a semi-solid component that interfaces directly to the user's body and face of the ultrasound transducer. These couplant assemblies can be shaped, molded, or otherwise machined and, in some embodiments, contain one or more liquid, gel, or other non-solid component in an enclosed reservoir of the couplant assembly. Beneficial embodiments of ultrasound coupling assemblies described herein include those that conform to the contour of the user's body (e.g. the user's head for transcranial applications) and can easily be removed without leaving a messy residue. By having solid materials physically contacting the body, no residue is left that requires cleanup.
