  • Transducer arrays with air kerfs for intraluminal imaging
    Patent number: 11504091
    Abstract: An imaging assembly for an intraluminal device is provided. In one embodiment, the imaging assembly includes: an array of ultrasound transducer elements spaced apart by air kerfs; a plurality of buffer elements surrounding the array of ultrasound transducer elements, wherein the plurality of buffer elements are spaced apart by gaps; and a sealing material filling portions of the gaps between the plurality of buffer elements.

  • Systems, methods, and computer readable media for high frequency contrast imaging and image-guided therapeutics
    Patent number: 9532769
    Abstract: Systems, methods, and computer readable media for high-frequency contrast imaging and image-guided therapeutics are disclosed. According to one aspect a method for high frequency contrast imaging and image-guided therapeutics includes: providing ultrasound of a first frequency bandwidth, directed toward the volume to be imaged, the volume containing a carrier having non-linear acoustical properties, wherein the ultrasound of the first frequency bandwidth causes the carrier to generate ultrasound of a second frequency bandwidth that is different from the first frequency bandwidth; receiving, from the volume to be imaged, ultrasound of the second frequency bandwidth; and using the received ultrasound of the second frequency bandwidth to generate an image of the volume to be imaged, wherein the components of the second frequency bandwidth that are detected are of a frequency greater than 20 MHz.
