Projections (assembling of transmitted beams) are recorded for several angular positions by rotating the sample between 0 and 180. Then, a back-projection algorithm is used to reconstruct 2D or 3D images, depending on the method used. In the case of 2D images each pixel has a grey level value corresponding to the local attenuation coefficient. |
