Octopus Imaging Software is one of the most versatile and performing packages for the processing of tomography data acquired in almost any geometry. Octopus Imaging Software provides an intuitive interface, an extensive Software Development Kit and high performance routines on various hardware configurations. Combined with unique features such as single slice evaluation, allowing to tune the reconstruction parameters without processing the complete volume, Octopus Imaging Software is an ideal solution for both novice and advanced users. We offer you 3 packages: Octopus Reconstruction, Octopus Visualization and Octopus Analysis.
3. 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
