Presents a model-based phase unwrapping method which represents the unwrapped phase function by a truncated Taylor series and a residual function. An efficient, noniterative computational algorithm is also proposed for calculating the model parameters from the phase derivatives. Sample experimental results are shown to demonstrate the effectiveness of the algorithm for extracting unwrapped phase images from two-dimensional (2-D) magnetic resonance imaging (MRI) data.
提出了一种基于模型的相位解缠方法，该方法通过截断泰勒级数和残差函数来表示解缠相位函数。还提出了一种有效的、非迭代的计算算法，用于从相位导数计算模型参数。给出了示例实验结果，以证明该算法从二维（2-D）磁共振成像（MRI）数据中提取无缠绕相位图像的有效性。
