Abstract
Magnetic resonance device comprises a patient support table and a main field magnet. The main field magnet is supported so that it can be rotated around at least one axis. The patient support table is able to be rotated around an axis essentially perpendicular in respect of its table surface.
Claims20
A magnetic resonance device used in a medical examination, comprising:
- a patient support table that is rotated during performance of an imaging scan by the magnetic resonance device, the table rotated during the performance of the imaging scan around an axis essentially perpendicular to a surface of the patient support table disposed to support a patient;
- and
- a main field magnet that is rotated during the performance of the imaging scan by the magnetic resonance device, the magnet rotated during the performance of the imaging scan around a further axis, wherein a rotation of the patient support table around the essentially perpendicular axis is controlled by a controller so that a section of the patient being imaged as the table is rotated remains within an imaging field of view of a rotating magnetic field generated by the main field magnet as the main field magnet rotates around the further axis to record an image of said section of the patient.
A method for creating an image of a tilted layer of a patient by a magnetic resonance device, comprising:
- rotating a patient support table during performance of an imaging scan by the magnetic resonance device, the rotating of the table being around an axis essentially perpendicular to a surface of the patient support table disposed to support a patient;
- providing a main field magnet that is shorter than a normal main field magnet used in a normal magnetic resonance device in a longitudinal direction of the patient support table;
- rotating the main field magnet during the performance of the imaging scan by the magnetic resonance device, the rotating of the magnet being around a further axis for positioning the tilted layer in an area of a homogeneous magnetic field;
- controlling a rotation of the patient support table around the essentially perpendicular axis so that a section of the patient being imaged as the table is rotated remains within an imaging field of view of a rotating magnetic field generated by the main field magnet as the main magnet rotates to record an image of said section of the patient.
