ABSTRACT:
A magnetic resonance (MR) probe head comprises a detecting device (3) with at least one antenna system which is cryogenically cooled by a cooling device, a cooled preamplifier (16) in a preamplifier housing (15a, 15b) which is spatially separated from the detecting device (3), and a thermally insulating connecting means via which the detecting device (3) and the preamplifier housing (15a, 15b) are connected, wherein the connecting means (15c) comprises at least one cooling line (9a, 9b, 53a, 53b) for supplying and/or returning a cooling fluid, and at least one RF line (10, 52) for transmitting electric signals. The connecting means (15c), including its RF and cooling lines (10, 52, 9a, 9b, 53a, 53b), can be separated from the preamplifier housing (15a, 15b) by a coupling. The MR probe head is an open system which can be used in a universal fashion through use of different measuring inserts. The system can be expanded for further measuring configurations at little cost and can be easily handled in a time-saving fashion with an optional arrangement having a flexible connecting line.
