  • Patent number: 7693321
    Abstract: In a method for determination of coronal and sagittal planes for the subsequent acquisition of new magnetic resonance slice images or the representation of magnetic resonance slice images from an existing image data set of a knee joint, starting from a data set representing a transversal slice image of the knee joint, the slice image is analyzed using at least one analysis algorithm to identify the medial and the lateral condyles of the femoral bone head shown as a transversal section and a point lying thereon in a section that defines a coronal plane that is tangential to the condyles. The sagittal plane proceeding perpendicular to the defined coronal plane is then determined. Coronal or sagittal slice images are then acquired or represented with orientations dependent on the identified planes.

  • Patent number: 7474912
    Abstract: In a method and magnetic resonance (MR) system for generation of localizer slice images of an examination volume of a subject for MR examination planning, such as for a whole-body examination of a patient, the localizer slice images being in three orthogonal planes, image data for the entire examination volume and acquired in the form of a family of individual, plane-parallel slice images in a first designated plane orientation for generation of a 3D volume image data set, a two-dimensional coronal or sagittal representation of the entire examination volume in the first designated plane is generated using the slice image family and is output to a monitor, for following image data acquisitions, of a desired examination region is selected in the representation of the entire examination volume on the monitor and is represented on the monitor as a localizer slice image for the first plane and the second and third localizer slice images in the two further orthogonal planes are determined using the 3D volume image

  • Patent number: 7365538
    Abstract: In a method and MR apparatus for acquisition of images of an examination region of a human or animal body by means of measurement parameter sets controlling the image acquisition, selection of an examination region to be acquired is made by a user according to anatomical viewpoints by means of a whole-body representation of an image element of the body (stored in a storage region for image data) on a monitor. A list of measurement parameter sets for the selected region is displayed on the monitor, with the measurement parameter sets in the list each being shown with at least one region-specific image element (stored in a storage region) of an acquisition result that can be obtained with this measurement parameter set. A measurement parameter set for image acquisition is then selected.

  • Patent number: 7227358
    Abstract: In a method for determination of coronal and sagittal planes for the subsequent acquisition of new magnetic resonance slice images or the representation of magnetic resonance slice images from an existing image data set of a shoulder joint starting from a data set representing a transversal slice image of a shoulder joint, the slice image is analyzed using at least one analysis algorithm to determine the shoulder blade and for two points lying on the shoulder blade that define the coronal plane. The slice image also is analyzed using at least one analysis algorithm to identify the shoulder blade and the half-moon-shaped arc of the joint connection between the had of the upper extremity of the humerus and the shoulder blade, and two points on the arc in the region of the joint connection with the shoulder blade that define the sagittal plane. A coronal slice image or a sagittal slice is then acquired or represented at the display dependent on the orientation of the identified planes.
