The results of simulation experiments for single channel data or arbitrary channel of multi-channel data show the clearer event, the better wave shape and the higher SNR compared with the conventional convolution filter and common SVR based on RBF. So it is possible that SVR based on Ricker wavelet kernel function is applied to suppressing noise in seismic prospecting data.

对单道记录或多道记录中任选道的仿真实验表明，与传统的基于径向基核函数的支持向量回归及褶积滤波方法相比，使用本方法去噪后的同相轴更为清晰，波形恢复得更好，信噪比也较高，因此有可能将其应用于地震勘探记录的去噪处理中。

Results In static phantom studies, the percent error of mean activity obtained by Carson's method was reduced to about 9 %, and it is less than that of image-derived method using maximum likelihood expectation maximization (about 14 %). In simulated dynamic phantom studies, the vessel component could be extracted using ICA in image and sinogram domain. In sinogram domain, the six components extracted by ICA could be obtained quickly.

在静态物理假体实验结果来看，使用Carson's method计算出感兴趣区域活性的百分比误差( 9%)比直接从影像取得活性的百分比误差( 14%)来得小；从数位模拟动态假体实验结果来看，独立成份分析法运用在影像空间或是弦波图空间上，都可以将血管分离出来，但从弦波图空间上得到各个独立成份相对於影像空间就快得多；imageICA和sinogramICA计算出的输入函数的标准化均方根误差分别是0.57和0.28。
