The system software is written in Visual C++ and implements two main
functions: (1) control of the operation of hardware and (2) image reconstruction. It employs 32-bit programming.
The following picture shows the Windows user interface.
Two image reconstruction algorithms are mostly used:
(1) linear back-projection (LBP) and (2) Landweber iteration.
Both algorithms offer real-time image reconstruction. The following pictures show images
of a plastic rod in air. Clearly, a much clearer image can be generated by the Landweber
iterative algorithm with 10 iterations than LBP.
The system software has been designed in such a way that users
can incorporate their own image reconstruction algorithm into
the system as a plug-in unit for their specific applications.
Therefore, the system is a powerful and flexible tool, and can be used for advanced research into industrial process tomography.
The system can also work with a twin-plane ECT sensor. The
picture below shows a screen shot of twin-plane operation.
