| Popis: | Iterative algorithms to reconstruct single photon emission computerized tomography (SPECT) data are based on the mathematical simulation of the acquisition process. The reconstruction times of these methods are much longer than that of routinely used reconstruction methods. Java, a platform independent programming language changed the way of software design by using Jini and JavaSpaces, new technologies which have been introduced recently. By applying JavaSpaces, a space is used to store objects persistently which can-be used also for effective parallel processing. In this paper, we report a novel approach for iterative reconstruction of SPECT data by means of JavaSpaces which uses only a standard personal computer equipment and results in significant improvement of reconstruction time due to the fact that several layers of the object are computed in parallel. |
