Automatic and Computationally Efficient Alignment in Fan- and Cone-beam Tomography
Patricio Guerrero, Simon Bellens, Ricardo Santander +1
This work is concerned with fan- and cone-beam computed tomography with circular source trajectory, where the reconstruction inverse problem requires an accurate knowledge of sourc…
