I try to use fanbeam function and ifanbeam to get the sinogram of a CT Image and after that rebuilding the image. I'm able to do the operation with the phantom image of same size as my CT image but it does not work for the CT image.

This is the code I use

Sinogram = fanbeam ( Im, 650, 'FanSensorGeometry', 'line' );
Image = ifanbeam ( Sinogram, 650, 'FanSensorGeometry', 'line' );

My CT image is 618x618 and I have normalized the intensity between 0 and 1. I obtain that never correspound to the original image. It is working ok for a phantom image of 618x618
