Abstract
Time‐Intensity Curves are often summarized by average curves. From these curves TI‐parameters are inferred. In this paper a different method is proposed in which the shape of the curves is the central concept. Isotropic scaling factors are computed for each curve. These factors can be tabled and inspected. Often a large number of scaling factors will be computed, which makes it hard to study them in a table. In such cases they can be represented in a plot, for which in this paper PCA is suggested. In this plot a structure in the scaling factors for the different TI‐curves may become visible. It is also possible to make a plot in which the homogeneity of the panel of subjects can be studied.
