Hi,

Has any of you ever tackled the problem of limited views in
tomographic reconstruction (i.e. projections with angular range less
then 180 degrees so that filtered backprojection can't give the
correct result)?

I'd guess you can extrapolate the sinogram somehow or interpolate in
Fourier space, but I have no idea how :-).

Greetings,

Wox
