چکیده

The watershed based cell reconstruction is a common approach to segment the cell system of foams and polycrystals. To avoid segmentation errors, a proper parametrisation of the algorithm is necessary. In this work, we propose a marker based method whose parameters are automatically adapted to the observed structure. The result is a nearly perfect cell reconstruction with segmentation errors below one percent.

A New Approach for Quantitative Evaluation of Reconstruction Algorithms in SPECT

ABTRACT Background: In nuclear medicine, phantoms are mainly used to evaluate the overall performance of the imaging systems and practically there is no phantom exclusively designed for the evaluation of the software performance.  In this study the Hoffman brain phantom was used for quantitative evaluation of reconstruction techniques. The phantom is modified to acquire t...
