| 摘 要： | 本文针对三维直肠超声导引前列腺介入式治疗中,针状手术器械定位难的问题,提出了一种三维超声图像中基于三维相位编组的针检测算法.该算法首先将体素按照梯度相位角进行分组,在得到的分组中用最小二乘拟合方法进行针状物体轴线提取,然后利用轴线体素的灰度统计特性进行端点定位.提出的方法在三维模拟数据、Agar 和鸡肉假体数据,以及三...

| Abstract: | This paper proposes a robust and efficient needle detection method,which is used to localize and track the needle in three-dimensional(3D) transrectal ultrasound(TRUS) guided prostate therapy.First,all voxels are grouped into different line support regions(LSR) based on the outer product of adjacent voxels' gradient vectors.The needle axis is extracted by least square fitting in LSR.The needle endpoint is localized by finding an intensity drop along the needle axis.Evaluation results in synthetic data,tissu... |
