Abstract
The physiological interpretation of factors in the factor analysis of dynamic radionuclide studies is dependent on the proper solution of the problem of factor rotation. A new solution suitable for scintigraphic data is suggested using a generalised concept of simple structure in data configurations. The method is described in detail, its efficiency is demonstrated on a phantom and its relationship to existing methods is discussed.
摘要
动态放射性核素研究的因子分析中各因子的生理学解释取决于因子旋转问题的恰当解决。利用数据结构中简单结构的广义概念，提出了一种适用于闪烁扫描数据的新解决方案。详细描述了该方法，在模型上展示了其有效性，并讨论了它与现有方法的关系。
