CT Reconstruction

CT Reconstruction
 

Iterative reconstruction algorithms for planar CT and special scan setups

High scan flexibility
Iterative reconstruction algorithms support virtually arbitrary CT scan trajectories. The list of supported trajectories is long – it includes sparse and limited angle CT for automatic X-ray inspection (AXI) of PCBs, circular tomosynthesis for analysis of fiber composite layers, or linear tomosynthesis of wind turbine blades, for instance.

High image quality
Iterative reconstruction algorithms converge in steps to the final solution and are thus not as fast as analytical reconstruction solutions. Though, if the projection count or angular sampling is small, an iterative reconstruction may deliver a better image quality in a short time.

Algorithms for high-speed or low-dose
CERA-ITR features both algebraic and statistical reconstruction algorithms. The algebraic approach is faster, while the statistical approach takes the noise statistics into account thus supporting low dose imaging.
