Detailed Description

Class PerfusionSkip.

This class provides functions to determine the number of volume to skip in the sequence. It attempts to give the number of volume that cannot be used due to the MR signal stabilization.

It operates as follows:

  1. Find the maximum intensity and its location in the first volume
  2. Follow the time evolution of this point until the intensity variation between two successive time falls under a threshold value. The threshold value is taken as a percentage of the initial amplitude.
