2.Image Reconstruction Sotware (IRS)

IRS is user friendly image reconstruction and post-processing software for Electrical Capacitance Volume Tomography (ECVT). The software is running on MATLAB version 6.0 or higher. Flexible options of using different image reconstruction algorithms are provided, including: linear back projection, iterative linear back projection, Thikonov regularization, and multi-criterion optimization. Post-processing software includes: various 3D permittivity graphical displays, various 2D image displays, 3D velocity mapping, 3D movie construction and display.  The software is compatible with Windows 98, 2000, XP OS. MATLAB software is not included in the software package.

Preprocessing window: showing reconstruction setting, reconstruction process in mini command window and display of reconstruction result. User freely sets up the reconstruction parameter and selects the algorithm.
