“…The reconstruction speed may be lower, as in particular iterative methods are slower, but acquisition could be simplified and accelerated, and such approaches could also benefit from much faster GPU reconstructions. Published work on TDM [17][18][19]27,[41][42][43][44]53,54,[86][87][88][89][90][91] have clearly demonstrated the usefulness of accessing the index of refraction distribution at microscopic scale, for biological research as well as work on artificial samples. But note that absorption is often not discussed, while it has been shown that refraction and absorption indeed provides complementary information [25,26,32,37,38,[45][46][47].…”
