reconstruct.rec_gridrec

Functions:

recon_gridrec(im1, im2, angles, oversampling)

Reconstruct two sinograms (of the same CT scan) with direct Fourier algorithm.

stp_core.reconstruct.rec_gridrec.recon_gridrec(im1, im2, angles, oversampling)

Reconstruct two sinograms (of the same CT scan) with direct Fourier algorithm.

Parameters:

• im1 (array_like) – Sinogram image data as numpy array.
• im2 (array_like) – Sinogram image data as numpy array.
• angles (double) – Value in radians representing the number of angles of the input sinogram.
• oversampling (double) – Input sinogram is rescaled to increase the sampling of the Fourier space and avoid artifacts. Suggested value in the range [1.2,1.6].
