Rescaling of the DSC source images. The DSC source images need to be rescaled to the same dimension to be suitable for a machine learning-based analysis. For this, all images that consisted of less than 80 time points were rescaled by copying the image of the last time point, where the contrast agent had already left the brain tissue. Essentially, this simply prolongs the baseline and has no effect on the parts of the time series that contain relevant information.
