4-DIMENSIONAL IMAGE DISPLAY FOR ASSOCIATED PARTICLE IMAGING

Associated particle imaging (API) is a three-dimensional neutron gamma imaging technique which provides both spatial and spectral informatio n about an unknown. A local area network consisting of a UNIX fileserv er and multiple DOS workstations has been chosen to perform the data a cquisition and display functions. The data are acquired with a CAMAC s ystem, stored in list mode, and sorted on the fileserver for display o n the DOS workstations. Three of the display PCs, interacting with the fileserver, provide coordinated views as the operator ''slices'' the image. The operator has a choice of: a one-dimensional shadowgram from any side, two-dimensional shadowgrams from any side; a three-dimensio nal view (either perspective projection or stereoscopic). A common col or scheme is used to carry energy information into the spatial images.
