Abstract
Data-blending presentation of scan data need not result in loss of significant resolution, the limiting factor being the detector collimator resolution. Some loss of contrast does occur. If too large a gaussian light spot is used, resolution loss is noted. In either case, with rectangular or gaussian spots, adequate counting statistics are required for interpretation of data with confidence. With the use of very narrow line spacing and larger light spots, conventional techniques approach the advantageous aspects of data blending which are less statistical fluctuation, reduction of motion artifact, better delineation of edges and shapes of objects, and removal of line structure. At the same time, the major disadvantage of data blending, i.e., loss of contrast, can be avoided.
