A system for obtaining a complete diagnostic description of an image sequence taken in nuclear medicine from the human heart has been developed, implemented, and tested. The knowledge about these images is represented in a semantic net, conclusions are drawn by a production rule approach, and scoring of alternative diagnoses is based on fuzzy membership… (More)
Focus maintenance is a challenging problem in multidimensional wide-field microscopy. Most automated microscopes use software algorithms, which are applied to z-sections of the object, to select for the plane with the best signal to noise ratio. When applied automatically in multidimensional imaging applications, auto focus routines significantly increase… (More)
Radioactive impurities known to exist in labeled diethylstilbestrol used in tissue residue studies in cattle include at least five different compounds, one of which is identified as pseudodiethylstilbestrol.
