    摘要: The invention relates to an image processing method of extracting geometrical data of the spine, for extracting the left and right pedicle landmarks of each spine vertebra, comprising steps of: acquiring image data of a 2-D frontal image of the spine; associating spine States to vertebra positions along the spine and estimating locations of left and right pedicle landmark Candidates in each State; defining a State Cost for forming Couples of left and right pedicle landmark Candidates (PL and PR); estimating sets of Best Couple Candidates, in each State, from the lowest State Costs; defining a Path Cost to go from one State to the next State; selecting a pedicle landmark Couple in each spine State (V) among the Best Couple Candidates from the minimum Path Costs, and localizing the left and right pedicle landmarks of each spine vertebra from said selected pedicle landmark Couple. The invention also relates to a system, a medical apparatus and a program product for carrying out the method.Application: Medical Imaging x-ray Medical System and apparatus; Program Product for Medical Imaging.

    摘要: An image processing method for providing three-dimensional geometric modeling of the spine, using a biplanar image reconstruction, comprising steps of acquisition of a first view (F) of a part of the spine, and a second view (L) of the same part of the spine taken from a different angle around the longitudinal axis of the spine, matching the dimensions of the views (F,L) from two predetermined corresponding landmarks (P1, P2) on each view and deriving three-dimensional coordinates (z, x, y) of corresponding points (P) along the spine. Application: X-ray medical 3-D imaging.

    摘要: The invention relates to an ultrasound images acquisition system. First, a first sequence of ultrasound images (I1) of an organ (LV) is acquired at a first image rate (IR1). Then a second sequence of ultrasound three-dimensional images (I3D—1) of a sub-volume (S_V1) covering a part of interest (RI/VI) in the first sequence (I1) is acquired at a second image rate (IR2) and a third sequence of ultrasound three-dimensional images (I3D—2) of a reference sub-volume (S_V0) is acquired at the second image rate (IR2). Finally the second and third sequences of three-dimensional images sequences (I3D—1, I3D—2) are compared.

    摘要: The present invention relates to a system for guiding a medical instrument in a patient body. Such a system comprises means for acquiring a 2D X-ray image of said medical instrument, means for acquiring a 3D ultrasound data set of said medical instrument using an ultrasound probe, means for localizing said ultrasound probe in a referential of said X-ray acquisition means, means for selecting a region of interest around said medical instrument within the 3D ultrasound data set and means for generating a bimodal representation of said medical instrument detection by combining said 2D X-ray image and said 3D ultrasound data set. A bimodal representation is generated on the basis of the 2D X-ray image by replacing the X-ray intensity value of points belonging to said region of interest by the ultrasound intensity value of the corresponding point in the 3D ultrasound data set.
