Once you have finalized your settings and selected “Optimize and Start Scan,” the Neptune system begins its automated capture and processing workflow. Here is what to expect during each phase.

​
Scanning

Before the scan begins, the system may capture Flat Field Correction (FFC) images to calibrate the scanner. To maximize your workflow efficiency, FFC data is cached locally for up to three days (72 hours). During this window, the system can reuse the existing images for Recipes and Repeat Scans, significantly reducing the total time required for each subsequent acquisition.
Note: For Horizontal Offset Scans or Helical Scans, the system will prompt you to remove your part for the calibration and reload it once complete. It is critical to follow these on-screen instructions. Failure to unload the part as directed can lead to hardware collisions and potential system damage.
Once the scan is officially underway, the touchscreen provides a real-time completion estimate. To ensure the highest fidelity and prevent motion-based artifacts, the machine should remain undisturbed until the acquisition cycle is finished.
Important: If an error message appears and the scan fails to complete, please take a clear photo of the error code and contact support@lumafield.com before scanning again.

​
Uploading and reconstruction

After the scanner finishes capturing projections, your scan data begins its journey to the cloud (or server if you have an on-premise configuration). The process involves two distinct stages:
  1. Uploading: Transfers the individual 2D X-ray projections to the cloud
  2. Reconstruction: Post-processes those 2D projections into a 3D volume of your part
You may see Projections appear in your Voyager project before the Reconstruction is available. This indicates the 2D images have uploaded successfully, and the Reconstruction is still in progress. Reconstructions will often take longer due to being computationally intensive - hundreds to thousands of high-resolution images are converted into a detailed 3D volume at this step. Because both stages involve large data transfers and significant processing, uploading and reconstruction can take up to 3 hours, depending on your facility’s network speed and current processing load.
Important: If a scan has completed but still has not uploaded or reconstructed after 3 hours, contact support@lumafield.com.
