Dependence of the reconstruction on the multipliers λI and λTV.
(a,c,e,g) A representative slices of the tomogram, (b,d,f,h) the corresponding absolute gradient image of the selected slices. The values of λI and λTV for the slices are also reported. The intensity scale of the images have been adapted for the best visualization of the blurring or the edge enhancement of the structures. The streaks are attributed to the missing wedge in the sampling scheme, and the images also highlight a curved artifact, which is attributed to a slight deviation of the tilt axis from the assumed direction.
