| | TB1DAM | flip | Double-angle B1+ mapping | The double-angle B1<sup>+</sup> method ([Insko and Bolinger 1993](https://www.sciencedirect.com/science/article/abs/pii/S1064185883711332)) is based on the calculation of the actual angles from signal ratios, collected by two acquisitions at different nominal excitation flip angles. Common sequence types for this application include spin echo and echo planar imaging. | | ||
| | TB1EPI | flip, echo | B1<sup>+</sup> mapping with 3D EPI | This B1<sup>+</sup> mapping method ([Jiru and Klose 2006](https://dx.doi.org/10.1002/mrm.21083)) is based on two EPI readouts to acquire spin echo (SE) and stimulated echo (STE) images at multiple flip angles in one sequence, used in the calculation of deviations from the nominal flip angle. | | ||
| | TB1AFI | flip, inv | Actual Flip Angle Imaging (AFI) | This method ([Yarnykh 2007](https://dx.doi.org/10.1002/mrm.21120)) calculates a B1<sup>+</sup> map from two images acquired at interleaved (two) TRs with identical RF pulses using a steady-state sequence | | ||
| | TB1TFL | Please see the qMRI appendix* | Siemens `tfl_b1_map` | B1<sup>+</sup> data acquired using `tfl_b1_map` product sequence by Siemens based on the method by [Chung et al. (2010)](https://onlinelibrary.wiley.com/doi/full/10.1002/mrm.22423). The sequence generates one ~anatomical image and one scaled flip angle map. | |

| \* These file collections call for the use of special notations that cannot | ||
| be resolved by entities that can generalize to other applications. Instead of | ||
| introducing an entity that is exclusive to a single application, method developers | ||
| who commonly use these file collections for the `MPM` application reached the consensus | ||
| on the use of `acq` entity to distinguish individual files. Please visit the qMRI | ||
| appendix for further details. |

I think an option to solve #683 (comment) would be to take this last paragraph starting with \* and put it at the top of the qMRI appendix, with a note right below, that more information will be added in the future.
Then in the table above all the * footnote references (which is broken markdown BTW, because it expects italics after an unescaped * chat) can be removed, and Please see the qMRI appendix can be turned into a true link instead.

follow up to #668, which I accidentally closed with a "git force push" while trying to rebase. I am still investigating where I went wrong ... 🤷♂️ Sorry everyone. Luckily there is
git reflogand I could recover all changes.
