Patent number: 10328463Abstract: Methods and devices are provided for suppressing reverberations within an ultrasound transducer with a backing whereby the backing may not sufficiently attenuate the acoustic energy by means of acoustic absorption and scattering alone. At least a portion of a surface of the backing is segmented into a plurality of levels defined by surface segments. The levels may be are spatially offset so that acoustic reflections from the segmented surface are spread out in time, thereby decreasing the net amplitude of the internally reflected waves as they interact with the piezoelectric layer. Adjacent (neighboring) levels may be spatially offset by a longitudinal distance equaling approximately an odd number multiple of a quarter of an operational wavelength of the transducer, so that destructive interference occurs from acoustic waves reflected from adjacent levels. Various example configurations of segmented surfaces are described, and methods for selecting a profile of a segmented surface are provided.Type: GrantFiled: November 21, 2014Date of Patent: June 25, 2019Assignee: SUNNYBROOK HEALTH SCIENCES CENTREInventors: Marc Lukacs, Brian Courtney, Chelsea Munding

Patent number: 9532769Abstract: 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.Type: GrantFiled: September 7, 2010Date of Patent: January 3, 2017Assignees: THE UNIVERSITY OF NORTH CAROLINA AT CHAPEL HILL, SUNNYBROOK RESEARCH INSTITUTEInventors: Paul A. Dayton, Ryan Gessner, Hyunggyun Lee, Marc Lukacs, Francis Stuart Foster

Publication number: 20160045184Abstract: Systems and methods are provided for localizing and visualizing devices with the use of an intracorporeal ultrasound imaging probe during a medical procedure. A primary intracorporeal ultrasound imaging probe is employed to image a three-dimensional region via scanning, and to locate a secondary intracorporeal device having one or more ultrasonic beacon transducers. When an A-scan vector associated with the primary intracorporeal ultrasound imaging device is directed towards one or more of the ultrasound beacon transducers of the secondary intracorporeal device, a communication signal is transmitted from the secondary intracorporeal device to a control and processing system associated with the primary intracorporeal ultrasound imaging device, either through acoustic transmission or non-acoustic transmission. Example embodiments are provided in which acoustic communication may be employed within the imaging band, or in a separate communication band distinct from the communication band.Type: ApplicationFiled: March 14, 2014Publication date: February 18, 2016Inventors: Brian Courtney, Marc Lukacs, Amandeep Thind
