- X-ray imaging system;
Low-density inclusions and voids in ceramics present a detection problem to X-ray imaging because of the relatively low contrast of the resulting image. An X-ray imaging technique xeroradiography has been in use for medical applications for detecting calcifications (low-density inclusions) in breast tissue. The method has a “built-in” edge enhancement. We have applied this technique to green and densified Si3N4 specimens and have shown initial improvements over other X-ray methods in the detection of seeded defects.
