| 英文摘要 | Magnetic susceptibility is the inherent property of materials. Magnetic resonance imaging as a kind of non-invasive testing technique may measure the magnetic field distortion induced by the imaging object and consequently calculate its magnetic susceptibility distribution. Conventionally, magnetic susceptibility mapping is performed in three-dimensional mode with the requirement of multi-slice scanning. In the condition of long objects that have uniform distribution along one direction, two-dimensional phase image of the cross section might be enough to estimate the susceptibility. In this study, we adjust susceptibility mapping algorithm into a two-dimensional mode and evaluate the possibility of using a single-slice image to estimate the magnetic susceptibility. Simulation was performed to validate the algorithm in both ideal and noise-imposed conditions. MRI experiment was performed by using copper, graphite and iron oxide at different concentrations. The results suggest that it is possible to measure the susceptibility of a long object by a two-dimensional image. |
