Three dimensional image reconstruction by histo-projections

Creators

Description

The reconstruction involves picking up position projections which are complete or incomplete depending on their inclination to the main axis and whether all their traces are seized by the detectors or not. The incomplete or complete projections pass through weighted retro-projection and filtering to produce two elementary images. The two elementary images are then combined to form a precise elementary image. 7 figs
