Joseph von Fraunhofer Prize 2018: New Dimension of X-ray Analysis
Researchers at Fraunhofer Institute for Integrated Circuits IIS succeeded in scanning objects as massive as freight containers, and analyzing them with three-dimensional images. As an X-ray source, the researchers use a linear accelerator with nine mega-electron volts (MeV) and combine it with an X-ray camera that works with a sensitive length of four meters and 10,000 pixels. For the first time, objects with a diameter of 3.20 meters and a height of five meters can be recorded with three-dimensional X-rays – special technology in which a large object is recorded in parts also allows the scanning of even larger objects. This makes the system the currently largest CT system in the world.
The objects are rotated on a heavy duty turntable. The camera and the radiation source scan the object synchronously in vertical motion, line by line. Due to the rotation of the turntable, the camera records many viewing angles, thereby creating the basis for the three-dimensional representation.
The Joseph von Fraunhofer Prize 2018 went to Michael Salamon, Nils Reims, and Dr. Michael Böhnel for the development of XXL computed tomography. This is the sixth time in a row that Fraunhofer IIS was honored with the prize.
