cart2grid

Interpolate a set of Cartesian points onto a binary grid

Syntax

[grid_data, order_index, reorder_index] = cart2grid(kgrid, cart_data)

Description

cart2grid interpolates the set of Cartesian points defined by cart_data onto a binary matrix defined by the k-space grid structure kgrid using nearest neighbour interpolation.

Inputs

`kgrid`	k-space grid structure returned by `makeGrid`
`cart_data`	1 x N, 2 x N, or 3 x N (for 1, 2, and 3 dimensions) array of Cartesian sensor points

Outputs

`grid_data`	binary grid with the same dimensions as the k-space input grid
`order_index`	the order that the Cartesian points appear in `grid_data` according to MATLAB's standard column-wise linear matrix index ordering
`reorder_index`	the order that the binary points in `grid_data` (according to MATLAB's standard column-wise linear matrix index ordering) appear in the original Cartesian data
