Tomographic inversion Matlab code
The code is based on the linear equations
Ax = b
where x represents pixel values of a tomographic image, A is the matrix of weight factors of the penetrating ray at pixel x, and b is the ray-sum measured from the experiment. The attached tomography codes technically construct A and b matrices and solve the linear equations using the iterative solver. The code contains one operation file, two function files for constructing A matrix, and one function file for the iterative solver (Kaczmarz’s method).
