I have a sequence of X-ray projections. It was taken from all the directions. How can I get a cross-sectional CT image using these 2D projections from different angles?

You could try iradon() or ifanbeam().

but iradon() or ifanbeam() uses only one image and then rotate it to different angles to get the different positions. On the other hand, i have already images from different positions. how can i use all of these to make one cross-sectional CT

iradon reconstruct the 2D image from multiangle 1D projections, so maybe you can choose the projection "line" in all views and arrage them into a 2D projection image named sinogram, and it is the R needed in iradon.

it does not work with iradon()
