mrinufft.trajectories.tools.conify(trajectory, nb_cones, z_tilt=None, in_out=False, max_angle=1.5707963267948966, borderless=True)[source]#

Distort 2D or 3D trajectories into cones along the \(k_z\)-axis.

Parameters:

  • trajectory (array_like) – Trajectory to conify.

  • nb_cones (int) – Number of cones repeating the provided trajectory.

  • z_tilt (str, optional) – Tilt of the trajectory over the \(k_z\)-axis, by default None.

  • in_out (bool, optional) – Whether to account for the in-out nature of some trajectories to avoid hard angles around the center, by default False.

  • max_angle (float, optional) – Maximum angle of the cones, by default pi / 2.

  • borderless (bool, optional) – Whether the cones should reach max_angle or not, and avoid 1D cones if equal to pi / 2, by default True.

Returns:

Conified trajectory.

Return type:

array_like
