Failed for 3D non-Cartesian trajectory #55

Closed Michaelsqj closed 2 years ago

Michaelsqj commented 2 years ago

Hi there,

I tried to use the torchkbnufft for 3D non-Cartesian trajectory for simulation. I used a 1x1x64x64x64 image and 3D radial trajectory as input to kbNufft for forward NUFFT and then use the acquired kdata for adjoint NUFFT, the output image doesn't look right. I'm wondering if torchkbnufft can be used for 3D non-Cartesian reconstruction? If so, are there any examples for 3D non-Cartesian reconstruction using this package?

Yours, Qijia
