Abstract
We proposed a CBCT-to-CT synthesis framework tailored for paediatric abdominal patients. Our approach was based on the cycle-consistent generative adversarial network (cycleGAN) modified to preserve structural consistency. To adjust for differences in field-of-view and body size from different patient groups, our training data was spatially co-registered to a common field-of-view and normalised to a fixed size. The proposed framework showed improvements in generating synthetic CTs from CBCTs compared to the original implementation of cycleGAN without field-of-view adjustments and structural consistency constrain.
