Abstract
The present utility model discloses a patient table for a magnetic resonance system, said magnetic resonance system also comprises a body coil, and said patient table comprises a table board and supporting means for supporting said table board, which table board is located in said body coil, and said supporting means supports said table board in such a way that the table board has no contact with said body coil. By using said patient table according to the present utility model, it is possible to eliminate the vibration of the table board caused by the vibration of a gradient coil, thus improving the imaging quality.
Claims15
A patient table for use in a magnetic resonance system, comprising:
- a table board that is located in a manner which independently floats and passes through or over a body coil of the magnetic resonance system;
- and
- a supporting device that supports the table board so that the table board has no contact with the body coil, said supporting device comprising a first supporting frame, a second supporting frame, and a driving mechanism;
- wherein the first supporting frame and the second supporting frame include a respective first end to support the table board and a respective second end fixed on a ground at two sides of a magnet of the magnetic resonance system without the first and second supporting frames having direct or indirect contact with the magnet of the magnetic resonance system, said second end being opposite to the first end;
- wherein said first supporting frame and the second supporting frame are decoupled from the magnet of the magnetic resonance system such that there is a physical separation space between the first and second supporting frames and the magnet of the magnetic resonance system whereby there is no direct or indirect contact between the first and second supporting frame and the magnet of the magnetic resonance system, and wherein when the table board is in an imaging position, the table board is vibrationally decoupled from the magnet of the magnetic resonance system such that a vibration of the magnet of the magnetic resonance system is not transmitted to the table board.
