  • Patent number: 6246239
    Abstract: An expanded diagnostic NMR installation with operating functionality contains an NMR imaging apparatus with a patient bed for transporting a patient into an imaging volume of the NMR imaging apparatus. An operating column for receiving the patient bed is arranged next to the NMR imaging apparatus at a fixed distance therefrom along the longitudinal direction of motion of the patient bed. The operating column contains a swinging mechanism for rotating or pivoting the patient bed around a vertical axis.

  • Patent number: 6026315
    Abstract: In a method and apparatus for calibrating a navigation system in relation to image data of a magnetic resonance apparatus, positions of at least three markers arranged in an imaging volume of a magnetic resonance apparatus are determined with the navigation system in a first coordinate system, and are determined by means of magnetic resonance in a second coordinate system. From the positions of the markers in the two coordinate systems, a position and an orientation of the two coordinate systems to one another are determined. Localization data are transformed into the second coordinate system. An apparatus for conducting the method has at least one marker having a substance that can be detected using magnetic resonance technology, in spatial allocation to optical markings. A pickup coil can be spatially allocated to each marker.

  • Patent number: 5879298
    Abstract: A control unit for a medical device has an actuation part and an electrical signal output that, due to an actuation of the actuation part, emits a control signal for a control computer of the medical device. The actuation device is secured to a work chair at the level of the heel of the foot of a person on the work chair.

  • Patent number: 5557204
    Abstract: In a turbo-spin echo sequence, nuclear magnetic resonance signals lying chronologically closer to an excitation phase are entered into a first raw data matrix for the acquisition of a proton-density-weighted image and nuclear magnetic resonance signals lying farther from the excitation phase are entered into a second raw data matrix for the acquisition of a T2-weighted image. Fewer rows are acquired for the first raw data matrix after every excitation phase than are acquired for the second raw data matrix. This avoids nuclear magnetic resonance signals that are already relatively strongly T2-weighted from being employed for the acquisition of a proton-density-weighted image.
