在这封信中，太赫兹（T-射线）计算机断层扫描（CT）成像的分割技术进行了研究。采用一组线性图像融合和新的小波尺度相关分割技术，实现了三维物体内的材料识别。所述方法被应用于从包含塑料管的塑料小瓶中获取的T射线CT图像数据集。该装置模拟了简单嵌套有机结构的成像，其提供了使用T射线CT成像实现非均质层的T射线脉冲信号分类的潜力的指示
In this letter, segmentation techniques for terahertz (T-ray) computed tomographic (CT) imaging are investigated. A set of linear image fusion and novel wavelet scale correlation segmentation techniques is adopted to achieve material discrimination within a 3-D object. The methods are applied to a T-ray CT image dataset taken from a plastic vial containing a plastic tube. This setup simulates the imaging of a simple nested organic structure, which provides an indication of the potential for using T-ray CT imaging to achieve T-ray pulsed signal classification of heterogeneous layers
