[求助] 求助英语

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.
