标准的临床磁共振成像(MRI)是在平面内分辨率高于切片选择方向的二维图像中获得的。这些获取包括轴位、冠位和矢状位。到目前为止，很少有人尝试将这三个正交方向的信息结合起来。本文的目的是利用每个平面方向获取的不同面内分辨率，将它们组合成一个体积，以获得更高分辨率的图像。MRI数据的这种组合将允许仅使用一个切片方向来检测否则将被遗漏的较小区域。执行切片厚度与图像配准的比较。计算均方误差和峰值信噪比，用于定量评估。使用MRI、体模扫描和关节直方图进行定性评估。
Standard clinical magnetic resonance imaging (MRI) is acquired in two-dimensions where the in-plane resolution is higher than the slice select direction. These acquisitions include axial, coronal, and sagittal planes. To date, there have been few attempts to combine the information of these three orthogonal orientations. This paper aims to take advantage of the different in-plane resolution acquired from each plane orientation and combine them into one volume in order to attain a higher resolution image. This combination of MRI data will allow the detection of smaller areas that would otherwise be missed using only one slice orientation. A comparison of slice thicknesses along with image registration is performed. The mean-squared error and peak signal-to-noise were computed for quantitative assessment. MRI and phantom scans and joint histograms were used for qualitative assessment.
