  • Patent number: 12178668
    Abstract: At least one example embodiment provides a magnetic resonance imaging system comprising at least one local radiofrequency (RF) coil; and at least one marker element, wherein the magnetic resonance imaging system is configured to activate the at least one marker element and deactivate the at least one marker element such that the at least one marker element is detectable by the magnetic resonance imaging system at a position relative to the at least one local RF coil if the at least one marker element is activated, and the at least one marker element is not detectable by the magnetic resonance imaging system if the at least one marker element is deactivated.

  • Patent number: 11835604
    Abstract: A method for ascertaining at least one of a position or an orientation of an MR local coil unit for arrangement inside a main magnetic field includes providing a first 3D relative position of a reference sensor system in relation to the main magnetic field; receiving an acceleration vector from at least one acceleration sensor; retrieving a distance vector describing a fixed relative position as a function of the received acceleration vector; calculating a second 3D relative position of the at least one acceleration sensor in relation to the main magnetic field based on the first 3D relative position and the retrieved distance vector; and ascertaining the at least one of the position or the orientation of the MR local coil unit using the first 3D relative position and the second 3D relative position.

  • Patent number: 11478197
    Abstract: A medical imaging apparatus, and a sensor arrangement for acquiring at least one item of patient movement information during a medical imaging examination, have at least one sensor element and a support apparatus, with the at least one sensor element arranged on the support apparatus. The support apparatus has a positioning element for positioning the support apparatus and at least one strut-like support element on which the at least one sensor element is removably arranged.

  • Publication number: 20160338614
    Abstract: A magnetic resonance apparatus has a scanner that has a patient receiving area, a position data acquisition unit, and a patient examination table of a patient positioning device. The table is movable within the patient receiving area. The position data acquisition unit detects a subarea, including an isocenter, of the patient receiving area, and provides position data to a speed regulating processor that regulates the speed of the table of patient positioning device depending on this position data.
