Improved lesion visualization using B-value maps based on thresholded DWI images

Diffusion weighted imaging is an increasingly popular method to detect and characterize dense tissues. The detection of such tissues is often performed based on high b-value images, as they show up as bright spots over a dark background. It has been shown that computed high b-value images as helpful as measured images. In particular it is helpful to interactively define the b-value for the computation. Here a new map is proposed that enables the interaction by simple windowing and can achieve an equivalent image impression to the high b-value images.
