"Patient bed arrangement for use in an open MR system"

Abstract

A patient bed arrangement for use in an intense-field magnet system which generates a vertical basic field for MR imaging, wherein two carrying supports are centrally symmetrically arranged between an upper magnet and a lower magnet of the magnet system, has a longitudinal axis that is oriented at an acute angle β of 45° relative to the connecting axis between the carrying supports.

I claim as my invention:  
     
         1 . In a magnet system which generates a vertical magnetic field between an upper magnet and a lower magnet and which has two supports connected to said upper magnet and said lower magnet which supports said upper magnet above said lower magnet, said supports being centrally symmetrically disposed relative to said upper magnet and said lower magnet, the improvement comprising: 
 a patient bed having a longitudinal axis mounted for orienting said longitudinal axis at an acute angle of 45°relative to a connecting axis proceeding between said carrying supports.    
     
     
         2 . The improvement of    claim 1    further comprising a lifting support connected at one end of said patient bed for inserting said patient bed between said upper magnet and said lower magnet  
     
     
         3 . A patient bed as claimed in    claim 2    wherein said patient bed is insertable between said upper magnet and said lower magnet along an insertion axis, and wherein said patient bed comprises a support plate mounted for displacement transversely relative to said insertion axis.  
     
     
         4 . The improvement of    claim 2    wherein said patient bed is pivotable around an axis of said lifting support.  
     
     
         5 . The improvement of    claim 2    wherein said lifting support is connected to one of said carrying supports.  
     
     
         6 . The improvement of    claim 5    wherein said lifting support has operating components associated therewith, said operating components being disposed at said carrying support to which said lifting support is connected.  
     
     
         7 . The improvement of    claim 2    wherein said lifting support is integrated with one of said carrying supports.  
     
     
         8 . The improvement of    claim 7    wherein said lifting support has control elements associated therewith and wherein said control elements are disposed at said carrying support with said lifting support is integrated.  
     
     
         9 . The improvement of    claim 2    wherein said lifting support has control elements associated therewith, and wherein said control elements are disposed at said lifting support.  
     
     
         10 . The improvement of    claim 2    wherein said lifting support has a lifting motor, and further comprising magnetic shielding for said lifting motor in said lifting support.  
     
     
         11 . The improvement of    claim 2    wherein said lifting support has a hydraulic lifting motor.  
     
     
         12 . The improvement of    claim 11    wherein said patient bed has a bed base, and wherein said hydraulic lifting motor is disposed in said bed base.
