X-ray CT: A solution where other imaging techniques fail
The investigation of the internal structures of an object is often a cumbersome process, since few techniques exist which allow to look inside without cutting the object. This study is however crucial to detect defects and imperfections in malfunctioning products (for example, an electronic component) or to investigate the structural composition of a material (such as the pore and grain structure of a rock sample). Therefore, companies often resort to destructive imaging techniques such as optical and electron microscopy, which require a substantial amount of sample preparation.
Destructive imaging techniques can not be applied for objects which need to be kept intact because of their value or need for use after structural investigation. Additionally, sample preparation itself can induce defects and deformation of the objects and lead to wrongful conclusion s. Also, the obtained information is often insufficient to provide a complete 3D characterization of the object, since typically only a single cross-section through the object is obtained. inCT tackles these issues by offering high quality X-ray CT scanning services as an alternative to destructive imaging techniques.
High quality 3D visualization of internal structures
X-ray CT provides a valuable solution to destructive imaging techniques, since a CT scan results in the generation of over one thousand virtual cross-sections through the object. These cross-sections can not only be used to detect defects or structures by visualizing them one by one, but they can also be combined into a complete 3D view of the object. inCT uses volume rendering software to cut the object virtually, render certain materials transparent (for example, a plastic layer around a ceramic component), and provides many more options to obtain a high quality and detailed visualization of the object in three dimensions.
