As imaging science/technology matures it becomes clear that it is more than an assorted collection of methods and devices each invented for a specific application. It is striking that the same ideas are used in such allegedly diverse fields as medical tomography and astronomy in searching for patterns in radar images as well as in quality control in the textile industry. What seems to be a fundamental unifying feature in all aspects of imaging is the brain's (still not well-understood) ability to parallel process an image and to simultaneously receive an array of data which would be impossible if received in numerical form. Some devices and algorithms are successful precisely because they strive to imitate or exploit this ability. Hence there is a need for a forum that can be used by people working on new principles of imaging its various hardware and software aspects algorithms and their derivations and their applications. The International Journal of Imaging Systems and Technology fills this need. It emphasizes unified approaches to various applications. By bringing together ideas and people working in different fields the Journal hopes to encourage interaction and cross-fertilization . Imaging is a multidisciplinary area. Hence the International Journal of Imaging Systems and Technology welcomes papers authored by physicists mathematicians engineers statisticians computer scientists as well as end users - radiologists geologists astronomers. The scope of the Journal includes but is not limited to the following: Acoustical imaging; Biophysical imaging; Computer vision; Cosmological imaging; High definition television; Medical imaging; Microscopy; Multidimensional image processing and tomography; Nuclear and particle physics imaging; Optical imaging and holography; Pattern recognition; Physiological imaging; Radar and synthetic aperture imaging; Seismic and geophysical imaging. All the submitted papers are reviewed by at least two referees. The editors try to maintain very high standards and papers are judged primarily on the ideas they contain novelty and relevance. All submitted papers should be sent to: Professor Z. H. Cho Department of Radiological Sciences University of California Irvine CA 92127
