## Description
General blabla
This work investigates an open-source, low-cost, 8-channel transmit/receive head coil to enable rapid and reproducible pTx development, safety assessment and evaluation at 3T. FDTD simulations were validated with phantom measurements on a 3T with an external pTx system. Relative and absolute 2D/3D B1+-maps were acquired to compute the CP+ mode, and two RF shims were tailored to enforce B1+ efficiency and homogeneity. The open-access design files could serve as a basis for new RF coil designs or pTx projects without needing high expertise in RF coil development or as a cost-effective alternative for multi-centre studies.
## RF coil specifications
- 8-channel transmit/receive
- f=128MHz
- outer dimensions: XX x XX x XXcm
- inner dimensions: XXcm
- bla bla
- B1+ efficiency: XX
- inner dimensions: 22x20cm
- B1+ efficiency: about 35µT/sqrt(kW) in the center (CP+ mode)
