mrinufft.density

Density compensation methods.

Tip

Density methods are available through the get_density function, that can be used by calling get_density(<key>) or with get_density(<key>, *args, **kwargs). Here are the function available from the registry:

Key	Function
"voronoi"	voronoi(traj, *args, **kwargs)
"cell_count"	cell_count(traj, shape, osf=1.0)
"pipe"	pipe(traj, shape, backend='gpunufft', **kwargs)

Functions

cell_count	Compute the number of points in each cell of the grid.
flat_traj	Decorate function to ensure that the trajectory is flatten before calling.
get_density	Get the density function from its name.
pipe	Compute the density compensation weights using the pipe method.
voronoi	Estimate density compensation weight using voronoi parcellation.
