从平行束投影探测断面内边缘的小波方法

Detection of Edges within the Cross Sectionfrom Projections of Parallel Beams Via the Wavelet Method

运用小波分析方法，从平行束射线投影探测断面内边缘。可应用于计算机断层摄影术（ＣＴ），以降低噪声和减少投影点。

The wavelet analysis are used in the detection of edges within the cross sectionfrom projections of parallel beams. This method can be applied in computerized tomography (CT) inorder to reduce the noise and the number of projections.
