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

  

• 128 by 128 two square phantom

  

Radon transform results

• 128 by 128 simulated head phantom

• 128 by 128 two square 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
