Inverse Problems

Solving Linearised Inverse Problem:




     does not exist, as A is generally under-determined, i.e. not symmetrical
Inverse Problem with Tikhonov Regularisation

Solving Inverse Problem:




                                  Regularisation
                                   Parameter
Imaging Result
Images are reconstructed using a linearised reconstruction
method based on inversion of a sensitivity Jacobian matrix
with Tikhonov regularisation
More Imaging Result
Suitable for metallic object imaging!

Rotational MIT (RMIT)

•   Electrical Tomography – low imaging resolution
•   Coil array can be rotated with respect to the central axis
•   Better Image Quality with the same amount of sensors

Pipeline Inspection

• Pipeline Inspection is important in industry:
   – undiscovered damaged pipelines => huge
     operational cost + environmental disaster
• Current Techniques
   – Non-destructive testing (NDT)
   – In-service testing: pipeline inspection gauges (PIG)
   – High Cost and Highly skilled technicians required
MIT in Pipeline Imaging
• Low cost, but yet provide a satisfactory imaging
• In-situ imaging
Narrow Band-pass MIT in Pipeline Imaging

• Narrowband filtering is a technique that can
  increase the image quality at the area of interest

Conclusion

• MIT is a suitable technique for conductive
  material imaging and NDT testing
• Low cost
• Image quality can enhance further by
  implementing different measuring techniques or
  reconstruction algorithms
• Satisfactory Imaging Result
• Close to commercialisation state

Kent Wei - Magnetic Induction Tomography Current Development and Potential Industrial Applications

  • 1. Magnetic induction tomography – current development and potential industrial applications Presented in Kuwait, Electronics and Electrical Engineering Faculty 4th October 2011 Presenter: Kent Wei, on behalf of Dr. Manuchehr Soleimani
  • 2. Magnetic Induction Tomography (MIT) work in Bath
  • 3. Outline • Introduction to Magnetic Induction Tomography (MIT) – Background – MIT Theory – System Design – Software Design – Image Reconstruction Algorithm – Rotational MIT – MIT in Pipeline imaging – Other tomography techniques
  • 4. Background (MIT) • Feature: – Most recently explored electrical tomography technique, compare with other electrical tomography systems, such as EIT and ECT – Contactless Electromagnetic Imaging. • Application: – Metal detection – Industrial non-destructive testing (NDT) – Medical application
  • 5. MIT Theory • Mutual Inductance • Sensor response
  • 6. MIT System Design Bath MIT Mk-I and Mk-II
  • 7. MIT Instrumentation Design • LabView • NI-USB 6259
  • 8. Image Reconstruction Forward Model (MIT) Conductivity Distribution Forward Model Sensor Measurement Inverse Model (MIT) Sensor Measurement Inverse Model Conductivity Distribution
  • 9. Forward Problems H-field (d/dt) excitation coil measuring coil Object eddy current H-field (d/dt) 1       E  i (  i )E   iJ e  
  • 10. Inverse Problems Solving Linearised Inverse Problem: does not exist, as A is generally under-determined, i.e. not symmetrical
  • 11. Inverse Problem with Tikhonov Regularisation Solving Inverse Problem: Regularisation Parameter
  • 12. Imaging Result Images are reconstructed using a linearised reconstruction method based on inversion of a sensitivity Jacobian matrix with Tikhonov regularisation
  • 13. More Imaging Result Suitable for metallic object imaging! HY Wei, M Soleimani, A simple magnetic induction tomography system and the image reconstruction (Published: The 4th World Congress on Industrial Process Tomography)
  • 14. Rotational MIT (RMIT) • Electrical Tomography – low imaging resolution • Coil array can be rotated with respect to the central axis • Better Image Quality with the same amount of sensors HY Wei, M Soleimani, Theoretical and experimental evaluation of rotational magnetic induction tomography (Accepted: IEEE TRANSACTIONS ON INSTRUMENTATION AND MEASUREMENT) No rotation: 28 One rotation: 28x2=56 Two rotations: 28x3=84 measurements measurements measurements
  • 15. Rotational MIT 0 10 No rotation One rotation with 22.5 degree Normalised singular values -1 Two rotations with 15 degrees 10 -2 10 -3 10 0 10 20 30 40 50 60 70 80 90 Measurement number
  • 16. RMIT Image Result No rotation One rotation Two rotations
  • 17. RMIT Image Result No rotation One rotation Two rotations
  • 18. Pipeline Inspection • Pipeline Inspection is important in industry: – undiscovered damaged pipelines => huge operational cost + environmental disaster • Current Techniques – Non-destructive testing (NDT) – In-service testing: pipeline inspection gauges (PIG) – High Cost and Highly skilled technicians required
  • 19. MIT in Pipeline Imaging • Low cost, but yet provide a satisfactory imaging • In-situ imaging
  • 20. Narrow Band-pass MIT in Pipeline Imaging • Narrowband filtering is a technique that can increase the image quality at the area of interest Reconstructed Image Reconstructed Image without narrowband with narrowband filtering filtering
  • 21. More narrowband filtering MIT result Damaged Tube with medium Hollow Tube opening with no opening Damaged Tube Damaged Tube with large with small opening opening
  • 22. 3D Industrial MIT - Simulation Sensitivity Map
  • 23. Movement of the centre of mass - Result Copper bar Predefined Movement of the center of pattern mass extracted from the image reconstructions
  • 24. Movement of the centre of mass (Simulated Result) Woods metal phantom Movement of the centre of mass extracted from the image reconstructions
  • 25. Flow Imaging Result Aluminium cone- shaped phantom Reconstructions of the boundaries for every 2 consecutive images Reconstructions of the boundaries for every 2 consecutive images
  • 26. Conclusion • MIT is a suitable technique for conductive material imaging and NDT testing • Low cost • Image quality can enhance further by implementing different measuring techniques or reconstruction algorithms • Satisfactory Imaging Result • Close to commercialisation state
  • 27. Improved FEM Model for 3D ECT an insulation (15mm) an outer screen imaging volume a mounting pipe (3mm) a top view of sensor
  • 29. Question? Kent Wei: H.Wei@bath.ac.uk Manuchehr Soleimani: M.Soleimani@bath.ac.uk
