Limited data CT techniques are getting increasing interest in many fields, given their advantages in acquisition time, exposure to radiations and device design. However, the object reconstruction process, in simulations as well as in real world situations, requires to estimate in some way the forward operator, that models the acquisition geometry. The talk will deal with one such approximation technique and how its vectorization impacts on the overall time and quality of the reconstruction.
