Draft structure of the 3D object
A cross-section to be reconstructed
Result of a classic method
Adjustment of radius, centre or attenuation coef. of one of the circles, in agreement with the restrictions
using 2, 3 & 4 noiseless projections
Additive noise of uniform distribution
0% 5% 10% 20%
using 4 projections, in case of 5, 20 & 40% of noise
Result of convolution backprojection
from 60 projections
Result of our method
from 4 projections seen above
