Imalytics > Software > CT Recon
Iterative CT reconstruction, built for any challenge.
Imalytics CT Recon combines fast GPU acceleration with automatic artifact correction to efficiently reconstruct µCT data. A live preview allows you to review the results and optimize the settings before starting the full reconstruction.


About CT Recon
Built to get more out of your data.
CT Recon takes raw projection data from your µCT scanner and reconstructs it into a 3D volume ready for analysis. Because it's iterative, you can easily introduce known priors into the system. That's what gives CT Recon the ability to address 6+ different artifacts.
- Built for artifact-heavy data: metal, motion, noise, and more
- Suited to new or non-standard CT system development
- Correct detector angle and offset without re-scanning

ArtIfact Reduction
Cleaner volumes, without the manual cleanup.
GPU-accelerated
Iterative reconstruction on NVIDIA hardware.
6 artifact classes
Corrected automatically or on demand.
GUI + console
Same engine, interactive or scripted.

Reconstruction Fidelity
Sub-voxel detail, even in fine structures.
Choose iterative reconstruction for maximum accuracy, or direct reconstruction for maximum speed. Either way, the fine trabecular detail that structural analysis depends on holds up.
Features
Control over every setting.
Automated where you want speed, adjustable where you want control.
Projection inspection
Review projection data, scan settings, and trajectory before you commit to a reconstruction. Catch problems early, not after the fact.
Iteration & voxel control
Set the number of iterations and voxel size directly, balancing reconstruction quality against processing time.
Binning & smoothing
Apply projection binning and smoothing to manage noise and file size ahead of reconstruction.
Field of view selection
Let CT Recon select the field of view automatically from a fast preview reconstruction, or set it manually yourself.
Calibration correction
Solve detector shift, source-to-detector distance, and detector angulation in software, semi-automated or by picking the sharpest slice yourself. Calibration drift stops costing you a re-scan.
Output format conversion
Export reconstructed volumes in the format your analysis software or archive expects.
Console Interface
Script your own reconstruction pipeline.
The console runs the same reconstruction engine as the GUI. Automate recurring jobs, queue a full night of scans, or fold reconstruction into a larger pipeline.
Technical Specs
System Requirements
CT Recon runs on Windows with an NVIDIA GPU. The GPU handles the reconstruction workload directly, and performance scales with the card you run it on.
Licensing
CT Recon is licensed to a single computer, tied to a hardware-specific token generated on that machine. Once activated, any user on that computer can run the software.
Input & Output Formats
CT Recon reads µCT projection data directly from the scanner and exports reconstructed volumes in the output format your downstream analysis software expects.
Automation
Every setting available in the GUI is also available from the console. Script a full pipeline, including overnight batches across many scans, and run it unattended.
Frequently Asked Questions
Do I need to reconstruct manually, or can it run unattended?
Both. Use the GUI to inspect data and tune settings interactively, or use the console to script a pipeline and queue scans, including running a full batch overnight.
What if my scans have motion or stitching issues?
CT Recon includes correction for respiratory motion and stitching artifacts, alongside ring, streak, cone-beam, and defect pixel correction, applied as part of reconstruction.
Can I set the field of view manually?
Yes. CT Recon can select the field of view automatically based on a fast preview reconstruction, or you can set it manually if you need more control.
