Arrangement for affixing a magnetic resonance rf coil to a patient

Abstract

In an arrangement to affix RF coils (in particular local coils) on a patient in examinations with a magnetic resonance apparatus, using a horizontal board to accommodate the patient for a magnetic resonance examination to be implemented; with the RF coil that has coil electronics; a fastening strap is fashioned to affix the coil on the patient and the fastening strap has an connection cable integrated therewith. The coil electronics are supplied with energy via the integrated connection cable.

1 . An arrangement to affix an RF coil on a patient for a magnetic resonance examination using the RF coil, comprising:
 a board configured to receive a patient thereon in a prone position for implementing a magnetic resonance examination of the patient;   an RF coil for use in said magnetic resonance examination, said coil having coil electronics physically associated therewith;   a fastening strap connected to the coil to affix the coil on the patient on the board; and   a connection cable connected to said coil electronics for supplying power to said coil electronics, said connection cable being integrated with said fastening strap.   
   
   
       2 . An arrangement as claimed in  claim 1  comprising a latch connection that connects said fastening strap to said board. 
   
   
       3 . An arrangement as claimed in  claim 2  wherein said latch connection comprises electrical contacts integrated therein. 
   
   
       4 . An arrangement as claimed in  claim 3  wherein said contacts are galvanic contacts. 
   
   
       5 . An arrangement as claimed in  claim 1  wherein said connection cable integrated with said fastening strap is connected with said RF coil via an electrical connection selected from the group consisting of a galvanic connection, inductive coupling elements and capacitive coupling elements. 
   
   
       6 . An arrangement as claimed in  claim 1  wherein said connection cable or said fastening strap comprises a signal coupler integrated therewith for transferring electrical signals between the RF coil and the connection cable. 
   
   
       7 . An arrangement as claimed in  claim 6  wherein said integrated signal coupler is a signal coupler selected from the group consisting of capacitive couplers and inductive couplers. 
   
   
       8 . An arrangement as claimed in  claim 7  wherein said RF coil has a housing comprising a coupler counterpart connected to the signal coupler to transfer signals between the RF coil and the signal coupler. 
   
   
       9 . An arrangement as claimed in  claim 8  comprising a fastening strap guide, and wherein said coupler counterpart is located below said fastening strap guide and is pressed by the fastening strap onto the signal coupler. 
   
   
       10 . An arrangement as claimed in  claim 1  wherein said RF coil is configured as a local coil.
