摘要： The invention relates to a support apparatus on which a patient can be supported in a comfortable and secure manner for the preparation for an examination and for the examination, in particular an endorectal biopsy. The support apparatus comprises a sliding apparatus connected to a bearing substructure and is supported in a displaceable manner on the sliding apparatus so that it can be moved partially beyond the substructure connected to the sliding apparatus. The support apparatus also comprises a cutout. The invention also relates to a patient support table comprising a connecting apparatus to connect the patient support table to the support apparatus and serving as a bearing substructure for the support apparatus. A medical device, in particular an MR device, is also disclosed comprising a patient tunnel and the patient support table that can be introduced into the patient tunnel.

摘要： A simplify mobile patient support apparatus which is suitable for an examination of a patient by a magnetic resonance tomography system is proposed. A first and second actuation facility and a control facility are used. Depending on the operating state of the patient support apparatus whether is docked with or undocked from the magnetic resonance tomography system, actuation of the first and second actuation facilities results either in the coupling or uncoupling of the patient support apparatus to/from the magnetic resonance tomography system or the raising or lowering of a patient support plate of the patient support apparatus. Essential components for docking or undocking or for the vertical adjustment of the patient support plate are integrated in a hydraulic unit.
