advantages is a speed so he used a compressed sensing technique with dictionary learning it takes around six hours to reconstruct an entire image sequence which in some clinical scenarios is acceptable but for example if you want to use your images for navigation because you want to for example perform a biopsy or something else then actually this is far too slow and the CNN is of course very very much faster so this actually now and now you can really do this probably in in 100 milliseconds so this is fast enough to
