摘要： In a method and apparatus for adjusting a table position in a medical data acquisition scanner, image data relating to a body region are generated by operation of the medical data acquisition scanner by running a scanning protocol. The scanning protocol is intended to be used independently of the body region that is mapped. An iso-mode, in which a relative position of the body region relative to the isocenter of the medical data acquisition scanner can be set via the table position in accordance with an optimization criterion, and on a ref-mode, in which the table position is set at a predetermined reference position, are provided. A mode of operation is selected from the iso-mode and the ref-mode as dependent on anatomical information relating to the body region and/or a relative position of the body region relative to the isocenter that ensues in the reference position, and before the running of and/or during the running of the selected scanning protocol, the table position is set according to the selected mode of operation.

摘要： In a method and magnetic resonance (MR) apparatus for implementing an MR examination of an examination subject with a predetermined MR measurement protocol at several different bed positions of the bed of the MR apparatus, a respective anatomical structure of the examination subject is determined for each of the several bed positions and a respective specific absorption rate is determined for each of the several bed positions as a function of the respective anatomical structure of the examination subject at the corresponding bed position and the predetermined MR measurement protocol. The specific absorption rates for the several bed positions are determined before electromagnetic fields are generated according to the respective predetermined MR measurement protocol. The specific absorption rates are compared with an absorption rate threshold value and a notification is output if at least one of the specific absorption rates exceeds the absorption rate threshold value.

The maximum measurement time parameter is used to restrict the ability of an operator to set a measurement time parameter describing the measurement time as a recording parameter, and/or is used as the measurement time parameter.
