Abstract
A coil comprises a set of windings with a generally annular shape and formed by a plurality of series-connected partial windings made of a superconductor with a high critical temperature, in which these partial windings are arranged next to each other in stratified form, and at least one cooling sheet which is made of thermally conductive material and arranged in contact with this set of windings and which is designed to be connected in a thermally conductive manner to a cryogenic cooling system.
Claims8
A magnetic resonance imaging apparatus, comprising:
- a magnet having a pair of poles connected to each other via a yoke, wherein each pole comprises a coil having a winding positioned within the poles, said winding having a generally annular shape;
- and
- at least one curved cooling sheet made of a thermally conductive material that is in thermal contact with the winding;
- and
- a cooling system that is in thermal contact with the at least one curved cooling sheet,
- wherein the at least one curved cooling sheet comprises a plurality of curved cooling sheets;
- wherein each of the plurality of curved cooling sheets includes a respective projecting portion to thermally connect to the cooling system.
