MDM-SIR (SIR-E3DTV)

This is the code of the iterative reconstruction method at Section III-E in paper MDM-PCCT

Requirements

  • Linux Platform
  • MATLAB
  • IRT

Describe

This model utilize an advanced prior term (enhanced 3DTV, E3DTV) for spectral and photon-counting data reconstruction. To solve the model, we use the alternating direction method of multipliers algorithm (ADMM).

Results

The following image shows the pig leg results of the compared methods, i.e., FBP, 3DTV, BM3D and the presented MDM-SIR methods, respectively. And zoomed ROIs indicated by the red box illustrate the details of the phantom.

Fig. 1. Results of the compared methods.
