1. A system of estimating b-values, the system comprising:
an electronic processor configured to
receive a set of medical images associated with a patient, wherein the set of medical images are diffusion-weighted images,
extract a set of patches from each medical image included in the set of medical images,
determine, via an estimation model trained using machine learning, a set of estimated b-values, wherein each estimated b-value is associated with a patch included in the set of patches,
determine a b-value for each of the medical images included in the set of medical images, wherein the determined b-value for each of the medical images is based on the set of estimated b-values, and
perform an image analysis function on the set of medical images based on the b-value for each of the medical images included in the set of medical images, wherein the image analysis function includes at least one selected from a group consisting of a segmentation function, a detection function, a classification function, and an arbitrary b-value DWI image generation function.
