The technology sounds interesting, but there isn't much inscription to use it on. At best it may illuminate a couple of broken letters and show that another possible letter is not there. (The English version incorrectly says that the last letter of line 3 is an aleph. The Hebrew article correctly says it is a he.)
The rest of the new material is Professor Galil's conjectural restoration of completely lost text. As always, one should be cautious about such conjectures.
You can see the Hebrew text in question in the Hebrew version of the article here. (HT Joseph Lauer.)
For previous discussions of Professor Galil's readings of other ancient lapidary Hebrew inscriptions that have or may have some connection with King Hezekiah, start here and follow the links. The evidence for some of these inscriptions remains to be published.
