MRI RF Coil Terminology
TERM | Description |
|---|---|
1H, 13C, 23Na (examples) | proton, carbon-13, sodium-23 |
1H/X coil | A double-resonant RF coil; |
1H-X coil | A single-resonant but tuneable RF coil, that can be tuned in the frequency range from 1H to X. |
200 (300, 400, 500, …..) | Designed for a magnetic resonance frequency of 200 MHz (…) |
2x2 | Array Coil design with 2 elements in 2 directions |
Active High / Active Low | Active High: A coil that can be actively detuned will be on-resonant while pin driver current flows to the coil. Active Low: A coil that can be actively detuned will be on-resonant while no current flows or even when disconnected. Check ParaVision -> Configuration -> RF Coils |
AD or AD2 | Active Detuneable (sometimes named decoupling instead of detuneable), enables Cross Coil Configuration (optimized for Cross Coil operation with minimum compromise when used for reception). |
ARR | Array Coil |
CP or CRP | Cryo Coil (CryoProbe™) |
part number ….V3 | designed for use in AVANCE III HD based instruments, |
part number ….V4 | designed for use in AVANCE NEO based instruments |
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. |
QUAD | Quadrature, synonym for circularly polarized electromagnetic field |
QSN/QNS | Quadrature RF coil, polarity south-north / north-south / unspecific. |
R., M., BR., HRT (examples) | Rat, Mouse, Brain, Heart |
RF | radio frequency |
RES | Resonator or Volume Coil |
RO | Receive-only coil, no signal excitation possible. |
SUC | Surface Coil, single or double resonant |
TR | Transceiver coil (transmit and receive coil) |
TO | Transmit-only transmitter coils, cannot be used for signal detection. |
TERM | Description |
|---|---|
Array Coil | A RF coil that consists of several elements, typically arranged as one or two dimensional array or ring structure (short ARR). |
Body Coil | A RF coil that allows to image parts of the body of an animal, but not the entire animal. |
Brain Coil | A RF coil that allows to image the brain of an animal, but not the entire head. |
Cross Coil (configuration) | A coil configuration that consists of separate RF coils for transmission and signal detection. |
Head Coil | A RF coil that allows to image the entire head of an animal. |
RF Coil | A single coil that is used in a RF coil configuration. |
RF Coil Configuration | A set of one or more RF coils that are used in a MRI experiment. |
RF Coil Element | One RF channel of a single or multiple element RF coil (array). |
Surface Coil | A RF coil that is placed on the surface and allows to image close to the surface (short: SUC). |
Volume Coil | A RF coil that allows to image typically homogeneously a volume. |
Whole Body Coil | A RF coil that allows to image the entire body of an animal (excluding the tail). |
