Rotation to simple structure in factor analysis of dynamic radionuclide studies.
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 forExpand

On the existence of an unambiguous solution in factor analysis of dynamic studies.
Achievement of an unambiguous solution in factor analysis of dynamic radionuclide studies depends on constraints reflecting the known properties of factors. The constraints should be tight enough toExpand

The Reality and Meaning of Physiological Factors
The term “physiological factor” was introduced by Bazin et al. (1979) for a time-activity curve detected above the separate compartment of a radio-pharmaceutical in the body. Considering formally theExpand

Enhancement of physiological factors in factor analysis of dynamic studies
Factor analysis of dynamic radionuclide studies provides their decomposition into the images and time-activity curves corresponding to the underlying dynamic structures. The method is based on theExpand
