A new microtomographic system has been assembled with a geometrical resolution of about 25–50 mm. This system is employed directly using the bremsstrahlung radiation and filtering the primary radiation with absorbers composed by an element. A reconstruction programme, written in PASCAL is able to give the reconstruction matrix of linear attenuation coefficients, simulates the matrix and the related tomography. Microtomography was studied thoroughly with different samples like acrylic cylinders containing internal W-wires of about 10 μm diameter, acrylic cylinders with holes of known diameters, small pencils with internal graphite, acrylic cylinders containing grains of soil and so on.
