Short description of the projectILATO is an acronym of Improving Limited Angle computed Tomography by Optical data integration. By measuring the intensity of X-ray beam after it travels through an object, the attenuation values of a specimen are acquired.
The project focuses on the registration of optically acquired surfaces with data acquired from computed tomography in order to enhance image quality and shorten acquisition times in X-ray based industrial quality inspection.
the registration of data sets created with considerably different imaging techniques, and the improvement of the applied methods.
All the extracted information is used to gain an improved visualization in the sense of less noise and sharper edges especially in the areas where the limited angle reconstruction suffers from insufficient information.
