Patent number: 10709403Abstract: A method of processing images for interventional imaging, wherein a region of interest is visualized, is provided. The method comprises acquiring a series of 2D images of the region of interest in a patient during at least one respiratory phase, acquiring an electrocardiographic signal which is synchronized with the acquisition of the series of 2D images, processing the electrocardiographic signal to estimate at least one deformation phase of the region of interest induced by the patient's respiratory movement, and registering the different successive 2D images in relation to the estimated deformation phase.Type: GrantFiled: January 24, 2013Date of Patent: July 14, 2020Assignee: GENERAL ELECTRIC COMPANYInventors: Maxime Cazalas, Regis Vaillant

Patent number: 10163211Abstract: A method for enhancing the visualization of a plurality of objects within an imaged subject. The method includes acquiring a plurality of images of the plurality of objects disposed in the imaged subject and supported by a plurality of guide wires; generating a complex deformation field based at least in part on a plurality of landmarks disposed in the plurality of images; and generating a composite image based at least in part on the complex deformation field. The complex deformation field models deformation induced on the plurality of objects by at least two or more guide wires of the plurality.Type: GrantFiled: January 26, 2016Date of Patent: December 25, 2018Assignee: GENERAL ELECTRIC COMPANYInventors: Regis Vaillant, Maxime Cazalas, Liliane Ramus, Sophie Amelot

Publication number: 20180235701Abstract: Methods and systems are provided for multi-modality imaging. In one embodiment, a method comprises: receiving planning annotations of a pre-operative three-dimensional (3D) image of a subject; during an ultrasound scan of the subject, registering an ultrasound image with the 3D image; overlaying the planning annotations on the ultrasound image; and displaying the ultrasound image with the overlaid planning annotations. In this way, pre-operative planning by a physician can be readily used during intervention.Type: ApplicationFiled: February 21, 2017Publication date: August 23, 2018Inventors: Olivier Gerard, Stian Langeland, Eigil Samset, Maxime Cazalas
