The forward projection algorithm is used in iterative reconstruction and gives insight into how projection data is acquired in CT imaging. The forward projection process is an addition operation; where we are adding up values in each pixel along the ray direction as seen in this Figure. This Fig...

The algorithm is called filtered backrpojection. Therefore, I should tell something about filtering. The filter used here is typical for phase computed laminography. The filter is in the form (cos(alpha) * sign(omega_u))/(i*4*pi). The sign has +1 values for positive omega_u spa...
