Overview

The Falken Nest TOFD Viewer is designed to display and analyze ultrasonic B-scans from .nde files. It uses the Falken AI to provide detailed results, including bounding boxes for detected features and a comprehensive checklist.

Ways to upload an NDE file

1. Use the Upload feature of the webpage: Use the file input or the "Upload" button to select and upload a .nde file containing ultrasonic B-scan data. This does not save anything, it is a view-only workflow.
2. Call with URL query parameters: Open the webpage with the following syntax:

   https://yourdomain.com/index.html?filename=example.nde&sdr=10&diameter=150&sdr2=12

   Where:

   • filename: The name of the .nde file to load (e.g., example.nde).
   • sdr (optional): The primary SDR (Standard Dimension Ratio) value for the pipe (e.g., 10).
   • diameter (optional): The diameter of the pipe in millimeters (e.g., 150).
   • sdr2 (double optional): A secondary SDR value if left and right pipe have a different thickness (e.g., 12).

   Note: Ensure that the filename is correctly specified and accessible by the application. If the SDR or diameter values are not provided, some checklist items will not be available. The secondary SDR value (sdr2) is only required for specific use cases and can be omitted if it's not needed.

Show and inspect the Falken AI results

1. View Results: Click the "Show algorithm results" button to display bounding boxes on the B-scan plot. The AI will highlight areas of interest such as indications, frontwall, backwall, backwall splitting, and surface anomalies.
2. Checklist: Click the "Show Checklist" button to view a detailed checklist with measurements and pass/fail criteria for various categories.

Other Features

• B-scan Plot: The main plot displays the B-scan image. You can click on the plot to update the A-scan view.
• A-scan Line: A red line indicates the current A-scan position. Clicking on the B-scan updates this line and the A-scan trace.
• Zero Line: A yellow line marks the zero point in the B-scan.
• CLAHE Enhancement: Toggle the CLAHE enhancement checkbox to improve the contrast of the B-scan image.
• AI Results Overview: Displays a static HTML web page showing the BBox-Results and the checklist. This overview can be used to print or save the Falken AI results.

Troubleshooting

• No File Selected: Ensure you have uploaded a .nde file before attempting to view results or the checklist.
• Upload Failed: If the upload fails, try reloading the page and uploading the file again. Contact support if the issue persists.
• Diameter and SDR Out of Range: Ensure that the diameter is between 63mm and 2000mm, and the SDR is between 6 and 51. The thickness (Diameter / SDR) should be between 10mm and 120mm.
• Results Not Available: If results are not available, upload a new file and wait for the AI to process it.
