Crutchfield Information Metric for Quantifying the Inter-sequence Relationship of Multiparametric MRI Data
Jens Kleesiek, Armin Biller, Kai J. Ueltzhöffer · 2015
A plethora of different MRI sequences exists. To automatically structure this ’zoo’ of available sequences we propose the usage of a framework rooted in information theory. In this paper we show that the Crutchfield information metric is a suitable distance measure for this purpose. It is demonstrated that the physical relationship can be inferred with this metric solely based on the voxel intensities. As future applications we envisage MRI sequence quality control and standardization.
