Patent number: 11523800Abstract: The present invention provides scanning mechanisms for imaging probes using for imaging mammalian tissues and structures using high resolution imaging, including high frequency ultrasound and/or optical coherence tomography. The imaging probes include adjustable rotational drive mechanism for imparting rotational motion to an imaging assembly containing either optical or ultrasound transducers which emit energy into the surrounding area. The imaging assembly includes a scanning mechanism having including a movable member configured to deliver the energy beam along a path out of said elongate hollow shaft at a variable angle with respect to said longitudinal axis to give forward and side viewing capability of the imaging assembly. The movable member is mounted in such a way that the variable angle is a function of the angular velocity of the imaging assembly.Type: GrantFiled: June 1, 2020Date of Patent: December 13, 2022Assignee: SUNNYBROOK HEALTH SCIENCES CENTREInventors: Brian Courtney, Nigel Robert Munce, Amandeep Singh Thind, Victor Xiao Dong Yang, Francis Stuart Foster, Alan Soong, Brian Heng Li

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.
