RF Coil Terminology and Identification
The type plate of the coil contains information about properties and power specifications of the coil.
Head Coil | examination of the head of an animal |
Brain Coil | examination of the brain of an animal, but not the entire head |
Body Coil | examination of parts of the body of an animal, but not the entire animal |
Whole Body Coil | examination of the entire body of an animal (excluding the tail). |
Volume Coil | a coil that covers a closed volume |
Surface Coil | a coil that is normally open on one side and covers a half volume |
Array Coil | A coil that has multiple coil elements and can be receive-only or a transceiver coil |
1H/X Coil | a double resonant coil; both resonance frequencies can be used simultaneously. |
1H-X Coil | a single resonant which can be tuned in the given range of nuclei |
transceiver coil | the coil can be used for signal excitation and signal detection |
receive-only coil | The coil can only receive signal, but cannot be used for signal excitation |
|
|
RF coil configuration | The coil configuration describes the set of one or more RF coils that are used in a study. The name of the configuration is defined by the user. |
RF Coil | a single coil that is used in a RF coil configuration |
RF coil element | one of the RF channel(s) of a single or multiple element RF Coil or coil array. |
RES | Resonator or Volume Coil. |
SUC | Surface Coil, single or double resonant. |
ARR | Array Coil. |
CRP | MRI CryoProbe TM |
AD | Active detuning, required property of all coils in a cross coil configuration |
TR | Transceiver coil |
TO | Transmit-only transmitter coils, cannot be used for signal detection. |
RO | Receive-only coil, no signal excitation possible. |
PC | PET Compatible. RF Coil can be used during PET applications. Typically for these RF Coils, attenuation correction maps are provided in ParaVision. Compare PO. |
PO | PET Optimized. RF Coil focuses on PET application with regard to FOV, material (low attenuation) etc. Typically for these RF Coils, attenuation correction maps are provided in ParaVision. |
QSN/QNS/QUAD | Circularly polarized RF Coil, polarity south-north / north-south / unspecific |
The type plate of the coil contains information about properties and power specifications of the coil, for instance as shown in the example below:
RES: | it is a resonator or Volume Coil |
400: | it is designed for 9.4T instruments (400 MHz) |
1H: | the coil is designed for 1H nucleus |
089: | the outer diameter is 89 mm |
060: | the inner diameter is 60 mm |
TR: | it is a transceiver coil without active detuning (no “AD” tag in the item) |
QSN: | circularly polarized (quadrature) coil for SN magnets |
