Publication number: 20050245814Abstract: The present invention discloses a method for determining the position and/or orientation of a catheter or other interventional access device or surgical probe using phase patterns in a magnetic resonance (MR) signal. In the method of the invention, global two-dimensional correlations are used to identify the phase pattern and orientation of individual microcoils, which is unique for each microcoil's position and orientation. In a preferred embodiment of the invention, tracking of interventional devices is performed by one integrated phase image projected onto the axial plane and a second image in an oblique plane through the center of the coil and normal to the coil plane. In another preferred embodiment, the position and orientation of a catheter tip can be reliably tracked using low resolution MR scans clinically useful for real-time interventional MRI applications.Type: ApplicationFiled: April 27, 2005Publication date: November 3, 2005Applicant: Sunnybrook & Women's College Health Sciences CentreInventors: Kevan Anderson, Graham Wright

Patent number: 6924643Abstract: Magnetic resonance imaging (MRI) uses direct, continuous, unaliased, real-time imaging for motion compensation. Unaliased, real-time two dimensional (2D) images are acquired continuously of the anatomy of interest. The images are compared to at least one template to using a correlation coefficient technique to select images corresponding to minimal motion and distortion. A spatial grid of templates can be used to cover an anatomy of interest. Multiple temporal templates can be used to create a time series of magnetic resonance (MR) images. The selected images are used to provide a high-resolution image, preferably a three dimensional (3D) image.Type: GrantFiled: September 3, 2003Date of Patent: August 2, 2005Assignee: Sunnybrook and Women's College Health Sciences CentreInventors: Marshall S.

Patent number: 6661230Abstract: Apparatus for nuclear magnetic resonance includes a sample container, a receiver coil adjacent to and surrounding the sample container and a flux return yoke for directing magnetic flux from the same falling outside the receiver coil back thereto, the yoke comprising a material having a variable magnetic permeability tuned for a particular frequency range. The material of the return yoke with a variable magnetic permeability includes an array of capacitive/inductive elements. Each capacitive/inductive element has a low resistance conducting path and is configured such that a magnetic component (H) of electromagnetic radiation lying within a predetermined frequency band induces an electrical current (j(x)) to flow around said path and through the associated element. The size of the elements and their spacing apart are selected to provide a predetermined permeability in response to the received electromagnetic radiation.Type: GrantFiled: July 22, 2002Date of Patent: December 9, 2003Assignee: Sunnybrook & Women's College Health Sciences CentreInventor: R.

Patent number: 6589174Abstract: The present invention is directed to an imaging-compatible device for insertion into a region of tissue under image guidance, which employs ultrasound energy for the generation of thermal lesions. Coagulation can be confined to particular sectors in tissue through rotational control of the device. The depth of coagulation can be controlled through simultaneous modulation of the operating frequencies and powers. Described is a device which comprises a transducer located within a housing suitable for tissue insertion. The transducer comprises at least one piezoceramic element with at least one acoustic matching layer comprising a high acoustic impedance material for generating acoustic energy in narrow passbands around multiple resonant frequencies with high acoustic efficiency.
