RF Interface Display
The RF interface display is located at the outside or on top of the CCM. The display provides information on different tabs to be toggled via touch screen display.
For routine operation, only the »Wobble« tab is relevant for the user:
- ▪
- Wobble: the wobble tab shows the module name and the corresponding tune/match (wobble) curve(s). The wobble process can be controlled by the following commands:
- –
- STOP: Stop the tune/match process.
- –
- PREV: Go to the previous channel (quadrature and/or double resonant coils).
- –
- NEXT: Go to the next channel (quadrature and/or double resonant coils).
The other tabs contain additional information for service and information purposes:
- ▪
- Modules: Contains a list of installed preamplifier and active detuning modules. For each module, the name, the current operation mode and the activated RF power limits are displayed. The following operation modes are used in MRI applications:
- –
- dec: This (default) mode is indicated for all modules, that are used for transmission only or that are unused.
- –
- obs: This module is in the observe mode and is used for data acquisition.
- –
- wobb: This mode indicates, that a module is currently used to tune/match a RF coil.
- –
- crp: This mode indicates, that a module is used in the operation mode for cryogenic cooled RF coils.
- –
- emStop: This mode indicates, that a module has encountered an emergency stop, i.e. because of power limit violation.
- ▪
- Devices: Contains a list of all devices detected at that moment by the automatic hardware identification system (HWIDS). The enumeration of the HWIDS ports 1 – 8 are assigned to the following devices. These are:
- ▪
- Service: Information on possible error messages. It contains additional information about the hardware and firmware versions of the preamplifier stack.
- ▪
- More: Toggles the display tabs Devices and MAS (MAS: magic angle spinning, not used for MRI).
