摘要:
介绍利用改进的左心室数字模拟器提供的核磁共振图像进行左心室运动重建的方法 ,即以双三次B样条曲面技术拟合短轴和长轴影像层 3个方向的标记面 ,达到亚像素精度。这对于跟踪心肌点几何位置 ,分析左心室的运动变形具有重要意义。
Abstract:
A method is given to describe the heart mot ion on the tagged mag net ic resonance images from a lef t ventricle dig ital simulator. Using a tensor product of bicubic B-splines, this paper represents tag planes in tw o orthogonal orientat ions intersecting the short-ax is image slices and tag planes in an orientat ion oryhogonal to the short-ax is tag planes intersect ing long-ax is image slices exhibited sub-pix el accuracy. This method is ef ficient so that the 3D motion of tagged point s can be measured and the motion deformation of lef t ventricle can be t racked.
