Radon Transform and Inverse Radon Transform

Goal

To Generate CT raw data (sinograms) of objects and to reconstruct the tomographic images

Source images

  • 128 by 128 simulated head phantom

    128Phantom

  • 128 by 128 two square phantom

    Sinogram_Source_-_Two_Squares_Phantom

Radon transform results

  • 128 by 128 simulated head phantom

Sinogram-128_Phantom

  • 128 by 128 two square phantom

Sinogram-Two_Squares_Phantom

code: RdTr3.m

Inverse Radon transform results

Filtered Back Projection (FBP)

  • 128 by 128 simulated head phantom

    Reconstruct image and animation over the project angles

  • 128 by 128 two square phantom

    Reconstruct image and animation over the project angles
