<p>The apparatus for locating nuclear radiation consists of a detection head containing a crystal to convert the nuclear radiation into light photons together with a set of transducers for converting these light photons into electrical signals (29). …<??>The electrical signals are received in a position encoder (18) which comprises, in series, a weighting system (30) for delivering analog signals X<+>, X<->, Y<+>, Y<-> (and possibly Z), a digitising system (32 - 40) for digitising the said analog signals, and a digital calculation system (42) for producing digital signals XN, YN defining the position of the nuclear radiation exciting the crystal. …<IMAGE>… </p> |
