Execution of Automated sequences via macro / scripting

Load acquisition and reconstruction profiles for sample series

Automatic calibration procedure of the geometry of the system


CT acquisition
‍The CT acquisition plugin allows tomographic acquisition with the following options:
‍
Standard single rotation, Horizontal stitching (“shift”),Vertical stitching (“stack”), Helical, Continuous rotation (local tomography, fast acquisitions)
‍
Reference acquisition for X-ray/sample movement compensation
‍
Multiple turns (acquisition split in several rotations for fast preview), Limited angle rotation, Laminography (no rotation: planar3D acquisition)

Anti-ring shift

Automatic black and gain calibration Stabilization sleep time

Automatic registration of the acquisition settings

Automation: one-click acquisition and reconstruction start for series of samples

Real-time 2D video radiographies

Guided acquisition mode for beginners and advanced user interface

‍

In-situ and customization:
Ready to use serial port communication plugin in X-Act software to control user hardware
“SDK” like package to implement your own plugins (custom demand)
Java-like scripting language for scripts and console
‍
CTreconstruction
‍
The reconstruction solution provided is a licensed plugin of X-Actsoftware called UniCT. It is a GPU accelerated CT reconstruction module mainly based on filtered back-projection algorithm. A complete set of tools is available to reconstruct acquisitions performed on PBMS XRAY system including:
Preview reconstruction of a running acquisition
Any direction slice preview
Full geometry correction, including automatic correction of therotation center
Focal spot drift, rings, bad pixel, beam hardening, phase contrast, metal artefacts real time correction (slice preview)
Easy and intuitive 3D optimization of the reconstructed volume: size, orientation and position of the bounding box. Possible import of previous acquisition settings to allow direct co-registration of theslices (valid if the sample was not removed from the stage or was placed at the same position)
Import menu to reconstruct data from 3rd party CT systems (including parallel beam projections like synchrotron acquisition)
TIF 16-bits image formats to allow user specific image processing before and/or after reconstruction.
Automation: enqueue preset projects and run batch reconstructions.
