Modeling and Experimental Limitations
| Sources of Simulation Error | Sources of Experimental Error |
|---|---|
| Numerical computation errors at regions of field discontinuity | Partial volume, resolution and averaging |
| Homogeneous transmit field approximation | SNR within reasonable scan time and slice thickness |
| Planar coil approximation | No signal from acrylic tube |
| Lumped element cable losses approximation | Phased array (receiver) coupling |
| Over-flipping artifact not captured | Reduced dynamic range (over-flipping seen as reduced field values) |
| Heat shrink tubing not conforming to coil dimensions | Fabrication limitations- in-plane positioning of coil conductors and tilt |
| B0 inhomogeneity (see [31] ) |
