Abstract
A method and an apparatus for generating a passive movement of a patient in a magnetic resonance tomograph. The apparatus includes a support for supporting at least one body part of the patient. The support, together with a patient bed can be moved into a passage of the magnetic resonance tomograph. Driven by a motor, the support can be swiveled about at least one axis inside the passage of the magnetic resonance tomograph. The components of the support and its drive, which are disposed inside the passage of the magnetic resonance tomograph, are made of non-ferromagnetic materials.

11. A method of acquiring images of a movement of a body or at least one part of a body of an object to be imaged in an imaging passage of an imaging modality comprising:
-
fixing the body or the at least one part of a body on a support to be disposed in the imaging passage; generating a defined reproducible passive movement about at least one axis of the body or the at least one part of a body or the support by a non-ferromagnetic motorized drive while disposing the support and the drive and the body or the at least one part of a body within the imaging passage; and acquiring a series of images continuously in real time while and during imaging and while or during the passive movement of the body or the at least one part of a body or the support. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36)

37. An apparatus for generating a passive movement of a body or at least one part of a body of an object to be imaged in an imaging passage of an imaging modality comprising:
-
a support for positioning the body or the at least one part of a body, which support can be moved into and disposed in an imaging passage of the imaging passage; a drive motor for providing a defined reproducible passive movement which can be moved into and disposed in the passage for applying pressure and/or movement and/or swiveling and/or pivoting and/or rotating the body or the at least one part of the body or the support about at least one axis inside the imaging passage; components of the support and the drive motor are made from non-ferromagnetic materials; and a control unit for controlling the drive motor to produce while and during the defined reproducible passive movement a series of images continuously in real time while or during imaging with the imaging modality. - View Dependent Claims (38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53)
