  • Patent number: 8515527
    Abstract: An imaging system for use in a medical intervention procedure is disclosed. A first image acquisition system is configured to produce a fluoroscopy image of an anatomical region. A second image acquisition system is configured to produce a 3D model of the anatomical region. An interventional tracking system, which includes a position indicator, is configured to maneuver within the anatomical region. A first anatomical reference system is common to both the first and the second image acquisition systems, and a second anatomical reference system is common to both the first image acquisition system and the interventional tracking system.

  • Patent number: 8073213
    Abstract: A method for generating a registered image relative to a cardiac cycle and a respiratory cycle of a person is provided. The method includes generating a plurality of 2-D images of an anatomical region of the person. The method further includes generating a 3-D model of the anatomical region of the person. The 3-D model is associated with a predetermined phase of the cardiac cycle and a predetermined phase of the respiratory cycle. The method further includes selecting a first 2-D image from the plurality of 2-D images associated with the predetermined phase of the cardiac cycle and the predetermined phase of the respiratory cycle. The method further includes generating the registered image of the anatomical region utilizing the first 2-D image and the 3-D model. The method further includes storing the registered image in a memory device.

  • Patent number: 7995819
    Abstract: Methods for displaying a location of a point of interest on a 3-D model of an anatomical region of a person are provided. In one exemplary embodiment, the method includes generating first and second 2-D images of the anatomical region utilizing an image acquisition system when an X-ray source of the image acquisition system is disposed at first and second positions, respectively, in a 3-D coordinate system of the image acquisition system. The method further includes selecting first and second points in the first and second 2-D images, respectively. The method further includes utilizing a triangulation technique utilizing the first and second points to determine a point of interest in a 3-D coordinate system of the 3-D model of the anatomical region.

  • Patent number: 7613500
    Abstract: A method for assisting the planning of an interventional biventricular pacing procedure includes segmenting an image dataset of a heart of a patient to extract a surface of a left ventricle (LV) and a LV myocardium of the patient's heart, utilizing the segmented image dataset to divide the LV into myocardial segments or into a plurality of short axis slices, and detecting wall motion of each short axis slice of phases of a cardiac cycle of the patient's heart with respect to a reference phase. The method also includes localizing a region most recently attaining maximum displacement and a region most recently attaining maximum velocity, and generating 2D or 3D renderings including renderings indicating at least one of time delays of contraction, a maximum displacement, or a maximum velocity.

  • Patent number: 7327872
    Abstract: An imaging system for use in a medical intervention procedure is disclosed. A first image acquisition system of a first modality employing a catheter at an anatomical region of a patient is configured to produce a first image of the anatomical region using fluoroscopy, the first image comprising a set of fluoroscopy projection images. A second image acquisition system of a second different modality is configured to generate a 3D model of the anatomical region. An anatomical reference system is common to both the first and second image acquisition systems. A processing circuit is configured to process executable instructions for registering the 3D model with the fluoroscopy image in response to the common reference system and discernible parameters associated with the catheter in both the first and second image acquisition systems.
