Out of the shadows.Out of the shadows A team of researchers has developed a powerful new mathematical procedure that allows them to reconstruct the internal structure of objects that diffuse, or scatter scat·ter v. 1. To cause to separate and go in different directions. 2. To separate and go in different directions; disperse. 3. To deflect radiation or particles. n. , incoming radiation, whether in the form of light, sound waves or particles such as neutrons. To produce an image of what lies within a solid target, the new technique relies on complicated, computer-intensive manipulations of data in the form of fuzzy "shadowgraphs" produced by an array of detectors that record the scattered Scattered Used for listed equity securities. Unconcentrated buy or sell interest. radiation emerging from the target. This imaging procedure has potential applications in medicine, industry and geophysics geophysics, study of the structure, composition, and dynamic changes of the earth, its atmosphere, hydrosphere and magnetosphere, based on the principles of physics. . For example, the analysis of shadowgraphs produced by infrared lasers probing animal tissue could produce images of the tissue's internal structure. J.R. Singer and his co-workers at the University of California, Berkeley The University of California, Berkeley is a public research university located in Berkeley, California, United States. Commonly referred to as UC Berkeley, Berkeley and Cal , describe their image-reconstruction technique in the May 25 SCIENCE. |
