【摘要】 磁共振波谱(MRS)在脑肿瘤诊断和治疗中具有重要的参考意义。磁共振波谱体素是所选择的感兴趣区(VOI)即肿瘤所在位置,其中包含了病变组织的代谢信息。本文分析了磁共振图像和波谱数据中的空间位置信息,利用VTK开发工具包,对连续二维医学图像序列进行虚拟三维重建,恢复出体素和连续图像序列的空间相对位置。同时显示勾勒出每张图像上的体素范围,把感兴趣区凸显出来;还可根据已有扫描结果,重新调节体素的大小使其包含更多的解剖范围,使医生能更精确地了解肿瘤在大脑中的位置和大小,再结合图像的波谱信息,对其进行更为细致的诊断。更多还原

【Abstract】 Magnetic Resonance Spectroscopy(MRS) has a profound contribution in the diagnosis and therapy of cerebral tumour.The voxel of MRS,which contains the metabolism information of diseased tissue,is the selected VOI(Volume of Interest) i.e.,the location of tumor.In this paper,the spatial location information of the magnetic resonance image and spectral data is analyzed,utilizing the development tool of VTK(the Visualization Toolkit),the virtual three-dimensional images of the continuous two-dimensional medical image series is reconstructed,the relative location of the voxel and the continuous image series is retrieved.Meanwhile,the range of voxel on each image will be demonstrated and sketched with the highlighted VOI.In addition,according to the scanning results,the size of voxel could be adjusted to cover a more detailed tumor region,which helps doctors to find out the location and size of the tumor in brain more accurately combining with the MRS metabolite information so as to carry out a more meticulous diagnosis.更多还原
