OCTOPUS AT A GLANCE

•  Octopus was originally developed for neutron tomography

•  Octopus Reconstruction extended towards other systems and geometries

•  Extended from solely reconstruction to Visualization and Analyis

•  New platform under construction*: Cloud solution


*in cooperation with Agfa Healthcare
