Abstract
We give the parallel sampling conditions of the 3D X-ray transform when the detector plane trajectory is a circle around the measured object. It turns out that hexagonal and interlaced sampling can be cormbined leading to an efficient scheme. In this case the detector is a rectangular grid. Numerical experiments from efficient schemes are provided.
