Detailed Description
template<std::uint16_t D>
class sirf::TrajectoryPreparation< D >
Abstract class defining the interface to set trajectories.
The strategy is to perform the trajectory computation as a pre-processsing step to the reconstruction. The ISMRMRD format has a 3D trajectory data field in their ISRMRMRD::Acquisition classe. The interface provides set_trajectory() which populates this data field depending on the implementation.

Sets the trajectory field in an ISMRMRD::Acquisition.
Depending on the virtual method calculate_trajectory(...) which is overloaded for child classes, this method fills the trajectory data field of the acquisition with the correct locations in k-space. The trajectory information is later picked up by the forward() and backward() methods of the MRAcquisitionModel.
