====== Allen Waggoner's tSense lecture ======

A few notes:

  * **intlv** should be on for interleaved slices
  * **ilts** controls how many shots are taken on the same slice before moving to the next slice
  * **pss** controls the order of the slices
  * Petable order usually hits the center of k-space on the first shot and then interleaves after that. The tsense program does not know what order the lines of k-space were taken so you have to specify that in its input (if not using Ken’s automatic version).
  * If the center of the image or a horizontal line through the center is bright this is usually called by a DC offset between the real and imaginary components of the receivers. This should be fixed with the new digital receivers on the new console
  * Other lines can be caused by a flow artifact in which fast moving blood through a part of the image causes phase errors.
