If the cross-section has no materials termed empty field, the measured values consist of K groups of regular distributions.
When there are materials in the cross-section, these measured decay rates are irregular.
The tested original images are a group of circles with continuously distributed materials, as shown in the first column in Table 1.

Popular materials used in recent years include various poly (l-lactic) biomaterials and collagen.
However, these materials have exhibited poor mechanical strengths and short degradation periods, both of which are disadvantageous as properties for scaffold materials in the development of tissue engineered tendon/ligament [4].

Morsi reports many processes applied to the reaction synthesis of Ni–Al intermetallics in which combustion synthesis has been recognized as a promising method for producing advanced materials.
It was found that this method cannot sinter large materials because the input heat by the laser is not enough.
At the same, powder compact can be sintered as whole in the vacuum furnace (TE), and this method can sinter larger materials.
