R is considered by many to be a free version of the earlier language S, which was developed at Bell Labs.
The basic data structures of R (vectors matrices, arrays, data frames, etc.) allow for efficient functionality in digital image processing. There are specialized packages in the language related to MRI and PET image processing.
