Method and device for generating a passive movement in a diagnostic device
First Claim
1. A method of acquiring images of a passive movement of a body or at least one part of a body of an object to be imaged in a magnetic resonance tomograph comprising:
- fixing the body or the at least one part of a body on a support to be disposed in an imaging passage of the magnetic resonance tomograph;
generating a defined reproducible passive movement about two independent axes of the body or the at least one part of a body or the support by a non-ferromagnetic motorized drive for the support while disposing the support and the drive and the body or the at least one part of a body within the imaging passage of the magnetic resonance tomograph; and
acquiring a series of images continuously in real time during imaging while or during the passive movement of the body or the at least one part of a body or the support.

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. An apparatus for generating a passive movement of a body or at least one part of a body of an object in a magnetic resonance tomograph 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 magnetic resonance tomograph; a drive motor for providing a defined reproducible passive movement which can be moved into and disposed in the passage of the magnetic resonance tomograph; the support or the body or the at least one part of the body can be moved or rotated or swiveled or pivoted independently about two axes; components of the support and the drive motor are made from non-ferromagnetic materials; and a control unit configured for controlling the drive motor to produce during the defined reproducible passive movement a series of images continuously in real time while or during imaging with the magnetic resonance tomograph. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 23, 24, 25, 27, 32, 36)
