摘要：

背景：磁共振波谱因其非侵入性和无创性，目前已被广泛应用于生物医学研究和临床应用，尤其是对脑肿瘤的诊断和治疗具有重要的参考意义。
目的：对磁共振波谱多体素进行空间位置配准，可以帮助医生更精确地定位大脑中的病变组织。
方法：利用可视化开发工具包VTK，对磁共振波谱多体素和二维医学图像进行三维重建，得到多体素、多体素中单个体素和图像在空间的相对位置。
结果与结论：实验基于VTK，实现了对磁共振波谱多体素的空间位置配准。

Abstract:

BACKGROUND: Magnetic resonance spectroscopy known for its non-invasive and non-destructive nature, has been widely applied in biomedical and clinical research. Especially it has a profound contribution in the diagnosis and therapy of cerebral tumor.
OBJECTIVE: The spatial location registration of magnetic resonance spectroscopic multi-voxel can help doctors to find out the location of diseased tissue in brain accurately.
METHODS: Utilizing the development tool of visualization toolkit (VTK), the virtual 3D voxel and 2D medical image were reconstructed in space coordinates. In addition, the relative spatial location of the multiple voxels, the single voxel of the multiple voxels and the image was retrieved.
RESULTS AND CONCLUSION: The spatial location registration of magnetic resonance spectroscopic multi-voxel is realized based on VTK.
