Iterative reconstruction algorithms produce accurate images without streak artifacts as in filtered backprojection. They allow improved incorporation of important corrections for image degrading effects, such as attenuation, scatter and depth-dependent resolution. Only some corrections, which are im

Though promising in nature, line detection algorithms based on fuzzy clustering su!er from excessive sensitivity to noise and non-linear structures. A new detection scheme is proposed here which is suitable for the processing of real-world images. Possibilistic clustering is used instead of fuzzy cl
A simple and powerful algorithm for a multiparametric search along a clinical Nuclear Medicine patient data base is described. It takes full advantage of the multiple linked list structure of the data base, aiming at the minimization of the time (i.e., disk accesses) needed to reply to the search re
## Abstract The concept of sentinel lymph node biopsy in breast cancer surgery relates to the fact that the tumor drains in a logical way via the lymphatic system, from the first to upper levels. Therefore, (1) the first lymph node met (the sentinel node) will most likely be the first one affected
