摘要： A magnetic resonance (MR) probe head comprises a detecting device with at least one antenna system which is cryogenically cooled by a cooling device, and a cooled preamplifier in a preamplifier housing which is spatially separated from the detecting device, and a thermally insulating connecting means via which the detecting device and the preamplifier housing are connected, wherein the connecting means comprises at least one cooling line for supplying and/or returning a cooling fluid, and with at least one RF line for transmitting the electric signals. The connecting means is implemented as a mechanically flexible connecting line with mechanically flexible RF lines and cooling lines disposed therein. The MR probe head is easy to handle and can be highly sensitive, wherein the detecting device can be quickly installed, removed and put into operation.

摘要： An NMR probe head for investigating a temperature-sensitive test object in a volume under investigation with at least one RF receiver coil which is cooled to cryogenic temperatures during operation, and is surrounded by a housing, wherein at least one heatable separating wall is provided between the RF receiver coil and the test object, is characterized in that the separating wall is produced from a material having excellent heat conducting properties, wherein the separating wall is coupled in a heat conducting fashion to at least one heating element at a separation from the volume under investigation via at least one contact location. The inventive NMR probe head permits disposition of the RF receiver coil in close proximity to the test object to be measured without inadvertently cooling it.

摘要： 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, and a cooled preamplifier (16) in a preamplifier housing (15a) 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 are connected, wherein the connecting means (15c) comprises at least one cooling line (9, 9a, 9b) for supplying and/or returning a cooling fluid, and with at least one RF line (10) for transmitting the electric signals. The connecting means is implemented as a mechanically flexible connecting line (8) with mechanically flexible RF lines (10) and cooling lines (9, 9a, 9b) disposed therein. The MR probe head is easy to handle and can be highly sensitive, wherein the detecting device can be quickly installed, removed and put into operation.
