We have the Radon transformation, in the most common form:
So what is the closed form of the derivative of Radon transform w.r.t $\phi$? Also the derivation details.
Also, I want to consider the derivative in the discrete form, i.e.,
in order to do numerical implementation. Not sure if I will have problems in implementation - but any advice welcome!
How to derive a closed form solution for an expression of $\phi$, from the Radon transformation, (maybe) with the use of the derivative of the Radon transformation.
I have searched for some literatures but seems couldn't find a satisfied answer.
Thanks in advance!
