  • Patent number: 8386016
    Abstract: In a method and device for determination of a position shift, first image data of a body region of a treatment-positioned patient that contain derivable temperature information are acquired. A focal area in the body region is determined, and the focus of a hyperthermia applicator can be aligned on the focal area. Second image data of the body region of the treatment-positioned patient that contain derivable temperature information are acquired, and a position shift of the focal area is determined by a comparison of the second image data with the first image data.

  • Publication number: 20120115346
    Abstract: The invention relates to a housing of a connector for making an electrical connection between the connector and a socket receiving same with at least a first and a second housing part which are releasably connectable with one another by means of a locking means and rigid fastening elements. The locking means comprises at least one locking bracket with two essentially parallel legs and one web which connects the legs, wherein each leg of the locking bracket comprises two locking arms which have connecting portions for a connection with the rigid fastening elements. The locking arms of the locking bracket are connected with the web of the locking bracket by at least one resilient portion, so that the relative distance between the locking arms of one leg is variable and the locking bracket is capable of clamping together the at least two housing parts.

  • Patent number: 8030922
    Abstract: In a method and device for correction of a B0 field drift in a temperature map acquisition by magnetic resonance tomography, a fluctuation measurement is calculated per pixel from a number of magnetic resonance tomography phase images of an examination subject or from temperature maps derived therefrom. Using this fluctuation measurement, pixels of the phase images or temperature maps with low fluctuation are determined, and corresponding pixels of a phase image to be corrected or of a temperature map to be corrected are selected using the pixels determined as having low fluctuation. The phase image to be corrected or the temperature map to be corrected is adjusted to a reference phase image or a reference temperature map such that the selected pixels of the phase image to be corrected or of the temperature map to be corrected are calibrated to corresponding pixels of the reference phase image or of the reference temperature map.

  • Patent number: 7760939
    Abstract: A method is disclosed for the generation of a background mask from an intensity-value-coded image with a noisy background area. The method includes generating an intensity value histogram of the image; fitting a model curve to a subarea of the intensity value histogram; calculating a threshold value in the intensity value histogram from the fit parameters of the model curve; and generating the background mask starting from at least one defined image area that belongs to the background noise by adding all the pixels whose intensities are below the threshold value to the background mask when connected to the image area via pixels whose intensities are also below the threshold value.

  • Patent number: 7633291
    Abstract: In a method for determination of a diffusion-weighted image of an examination subject in a magnetic resonance system, a diffusion-weighted data set is acquired with magnetic diffusion gradients being activated; a diffusion-weighted image of the examination subject is calculated using this diffusion-weighted data set; dephasing or spoiler gradients are activated in order to reduce artifacts in the diffusion-weighted image due to additional signal echoes and the position and/or amplitude and/or polarity of the dephasing gradients is/are selected dependent on the diffusion gradients.
