Technical Advantages for MRI Engineering
1. Why 32AWG Micro-Coaxial Cable is Crucial?
32AWG ultra-fine coaxial cables ($50\pm2\Omega$) are specifically selected for high-density, multi-channel MRI receiver arrays (Rx array coils). It ensures precise RF small-signal transmission with minimum attenuation in extremely constrained spaces. Where standard RG178 cables are too bulky to route inside compact medical coil housings, our 32AWG bundle provides the perfect mechanical flex life and space-saving solution.
2. Multi-Functional 18-Wire 28AWG Control Network
The 18 redundant 28AWG low-frequency signal lines are designed to handle complex background operations within advanced array elements:
- PIN Diode Control: Delivers stable DC bias currents for RF decoupling/detuning switches.
- Coil Identification (ID): Connects to internal ID resistors/EEPROMs for proper system recognition.
- Integrated Sensor Systems: Routes signals from active NTC/RTD temperature sensors and tune/match diagnostic networks without interfering with main RF imaging channels.
3. MRI-Compatible Non-Magnetic Shielding
Engineered purely for medical imaging environments, the overall shield relies entirely on a high-density non-magnetic braid without any copper foil or ferromagnetic elements. This advanced shielding topology eliminates the risk of image artifacts caused by eddy currents while ensuring robust EMI/RFI protection under high-field gradient environments.
FAQ about this 8-Channel MRI Cable
Is this cable suitable for high-power RF transmission?
No, this bundle is explicitly engineered for low-power RF receiver arrays (Rx Only), imaging probes, and diagnostic signal pathways. The micro 32AWG coaxial design offers elite flexibility and SNR for tiny echo signals but is not rated for high-power RF excitation transmission.
Can this line replace original GE 8-channel array cables?
Yes, the electrical properties (8x 50Ω coax + 18 control lines) are perfectly compatible with the architectural schematics of standard 8-channel array systems. However, since final termination pinouts vary by specific sub-models, we provide this as an open-ended bulk cable or custom-mapped assembly tailored to your specific connector configuration.
