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。
