基于ECT图像的微胶囊消化道轨迹三维重建方法

ECT-image based 3-D reconstruction method for traces of microcapsule in GI tract

为了重建微型胶囊在人体肠道内的三维空间运动轨迹,运用核医学成像原理,通过ECT拍摄原始实验图像,在V isual C++6.0环境下编写程序,运用矩阵变换进行图像数据处理,计算出微型胶囊的三维坐标。重建出了连续时间内,微型胶囊的人体肠道运动轨迹。与人体消化道钡餐造影图片对比,重建图能够较好地描绘出肠道走向。

The 3-dimisinal（3-D）traces of the microcapsule navigating are reconstructed through the gastrointestinal （GI） tract. The primitive experimental pictures of the microcapsule are taken via ECT by exploiting the imaging principle of nuclear medicine. Image and data processing is performed by matrix transform and then programmed by Visual C ＋＋ 6.0 to obtain the 3-D coordinates of the microcapsule. The traces of the microcapsule in the GI tract are reconstructed during continuous time. The results indicate that the contour of the GI tract can be better depicted by reconstruction drawings than by the barium meal picture.
