Abstract: A biopsy needle guide, which has at least two degrees of freedom and can be freely positioned at least in a plane, includes a through-passing opening for passing a biopsy needle through. In an interior of the opening, a fixing structure and a clamping structure are present, and an adapter sleeve is present, which has a continuous opening for passing a biopsy needle through, as well as a stop collar, and which can be pushed into the opening as far as the collar and is rotatable after pushing in as far as the stop. By rotating the adapter sleeve to a first angle at most, a latch structure of the adapter sleeve engages behind the fixing structure of the opening, so that the adapter sleeve is fixed in the axial direction. By rotating the adapter sleeve beyond the first angle, the latch structure interacts with the clamp structure such that a biopsy needle that is introduced in the opening is fixed in the axial direction.

Abstract: A reception coil maintaining element for an MR-imaging system includes two phase-controlled multi-element arrays of an RF multi-channel surface reception coil. Both of these phase-controlled, multi-element arrays have a reception surface including a center having a longitudinal axis that crosses that center. Each of these multi-element arrays is arranged on an arm which can pivot about a common pivotable axis. A vertical first plane is parallel to this pivotable axis. A vertical left plane extends along the longitudinal axis of the center of the left reception surface of the left multi-element array. A vertical right plane extends along a longitudinal axis of the center of the right reception surface of the right multi-element array. Both of these vertical left and right planes have approximately the same spacing with respect to the vertical first plane of the pivotable axis where the reception coil maintaining element in accordance with the present invention is in its operational state.
