Patent number: 7962194Abstract: A magnetic resonance imager (MRI) controllably propels at least one magnetic field responsive body within a subject. The MRI comprises a bore magnet producing an intense magnetic field sufficient to magnetically saturate the magnetic field responsive body. A magnetic field gradient generator is configured to apply variable magnetic gradients to at least a portion of the subject containing the magnetically-saturated body. A controller instructs the magnetic field gradient generator to acquire image data of the magnetically-saturated body within the subject and to apply a calculated magnetic gradient that will propel the magnetically-saturated body towards a target location in the subject. A tracking unit of the MRI provides position feedback information of the magnetically-saturated body within the subject.Type: GrantFiled: April 15, 2003Date of Patent: June 14, 2011Assignees: Polyvalor, Limited Partnership, Val-Chum, Limited PartnershipInventors: Sylvain Martel, Jean-Baptiste Mathieu, L'Hocine Yahia, Gilles Soulez, Gilles Beaudoin

Patent number: 7925064Abstract: The present invention generally relates to intravascular ultrasound (IVUS) image segmentation methods, and is more specifically concerned with an intravascular ultrasound image segmentation method for characterizing blood vessel vascular layers. The proposed image segmentation method for estimating boundaries of layers in a multi-layered vessel provides image data which represent a plurality of image elements of the multi-layered vessel. The method also determines a plurality of initial interfaces corresponding to regions of the image data to segment and further concurrently propagates the initial interfaces corresponding to the regions to segment. The method thereby allows to estimate the boundaries of the layers of the multi-layered vessel by propagating the initial interfaces using a fast marching model based on a probability function which describes at least one characteristic of the image elements.Type: GrantFiled: November 15, 2004Date of Patent: April 12, 2011Assignees: Val-Chum, Limited Partnership, Valorisation-Recherche, Limited PartnershipInventors: Guy Cloutier, Marie-Hélène Roy-Cardinal, Jean Meunier, Gilles Soulez, Eric Therasse
