=== EPI_HighRes_1.5x1.5x2mm ===
fMRI with 1.5 mm in-plane (highest achievable) spatial resolution, 2 s per volume. Keep in mind that acquiring slices with higher resolution leads to slightly fewer slices thus slightly more reduced brain coverage!

===== Fieldmap =====
Magnetic field mapping sequences required to 
  * undistort EPI data (e.g. fMRI, DWI)
  * measure functional sensitivity

:!: It has to be acquired with the same geometry (FOV, resolution, alignment, slice centre) as the EPI data! :!:
