Visualization imaging software design for Electrical Tomography

As a non-invasive detection method, Electrical Tomography (ET) can reach a much higher imaging speed than γ-ray or X-ray CT, etc. To archive an even higher speed, there are several factors which should be considered thoroughly, such as excitation/measurement strategy, data acquisition system design, communication protocol, reconstruction algorithm, imaging software, etc. To apply the wooden bucket theory to this situation, the slowest section determines the system´s actual speed. And imaging software becomes the lowest board in some cases. Based on Tianjin University Electrical Tomography (TJU-ET) hardware, this paper introduced optimized multithread program architecture, standard BLAS (Basic Linear Algebra Subprograms) and LAPACK (Linear Algebra PACKage) numerical library, optimized OpenGL rendering engine and many other improvements into imaging software. As a result, the brand new software can fully releases TJU-ET system´s power, which means it can perform 750fps on TJU dual plane 12-electrode ECT system.
