As always, thank you very much for your suggestion. You are always there

to help!

I have looked at the paper you found but think that the " floating point "

technique that they are using is the equivalent of the " virgule

flottant " , an IT/mathematical technique used for rapid calculation in

several areas including CT.

I was however convinced that my " foyer flottant " was something physical

so I continued searching most of the afternoon. Finally I came across a

Siemens American video on one of their CT machine under " z sharp

advantages " showing how the X-ray source is rapidly very slightly

displaced in the z axis to improve resolution of small objects which

they called " floating focal spot " . This fitted with my French definition

and having found that I managed to confirm it by finding some other

references to it e.g.

Almost an 8 hour day to translate a couple of words!

Thanks again.
