We
present a software platform called the General Trajectory Tester (GTT) that
allows users to input arbitrary 3D k-space trajectories, in an arbitrary
number of interleaves, which are then used to sample and reconstruct a known
3D analytical phantom. The GTT can
also simulate diffusion weighting, including arbitrary diffusion angular
encoding schemes for DTI, multiple b-values, eddy current and motion induced
artifacts and self-navigation, and so is a natural platform to test efficient
DTI acquisition and self-navigation schemes.
