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

Publication number: 20210212772Abstract: Systems and methods for surgical guidance and image registration are provided, in which three-dimensional image data associated with an object or patient is registered to topological image data obtained using a surface topology imaging device. The surface topology imaging device may be rigidly attached to an optical position measurement system that also tracks fiducial markers on a movable instrument. The instrument may be registered to the topological image data, such that the topological image data and the movable instrument are registered to the three-dimensional image data. The three-dimensional image data may be CT or MRI data associated with a patient. The system may also co-register images pertaining to a surgical plan with the three-dimensional image data. In another aspect, the surface topology imaging device may be configured to directly track fiducial markers on a movable instrument. The fiducial markers may be tracked according to surface texture.Type: ApplicationFiled: March 31, 2021Publication date: July 15, 2021Inventors: Victor Xiao Dong YANG, Beau Anthony Standish, Adrian Linus Dinesh Mariampillai, Michael Ka Kit Leung
