We present a new fast method of modeling 3-D objects of arbitrary topology. The Level Set Methods have been used by many researchers to recover 3-D shapes of arbitrary topology. However, those methods are computationally inefficient. To reduce the computational cost, a new method named FNB (Fast Narrow Band Method) is proposed. FNB is based on the Narrow(More)
We present a novel visualization method for finding care factors in variance analysis. The analysis has two stages: first stage enables users to extract a significant variance, and second stage enables users to find out a critical care factors of the variance. The analysis has been validated by using synthetically created inpatient care processes. It was(More)
We propose a new system to manage modalities in radiology departments. Our system introduces a novel method to accurately estimate some indexes in order to provide an analysis of resource plans within three broad categories: financial affairs, patient satisfaction, and productivity. The main idea is to simulate the operational status of modalities. Results(More)
