Hi. I am working with Radon transform. Is it possible to get the transformed image that has the same size as that of original image?

Whenever I calculate the radon transform of an image using the function 'radon' the size of the transformed data is different from the original image. How can I get the transformed data which is of the same size as that of the original image?

The result of the radon transform is in a totally different domain to that of your image (just like the fourier transform is in the frequency domain) so one of the dimensions is defined by the number of radial angles you choose and the other is defined by the longest distance across your image at the 45-degree angle (or the angle which gives maximal distance if 45-degrees is not included). Unless you only use 0 or 90 degrees as your theta that second dimension will never match that of the image.
