X ray radiation medical image generator having vacuum tube held cathode/anode with anode having elementary surfaces receiving/focussing electron beam.

摘要

The invention concerns an X-ray generator comprising a tube (2; 30) wherein prevails a vacuum, a cathode (3; 31) and an anode (5; 33) located inside the tube (1; 30), the cathode (3; 31) generating an electron beam towards the anode which transforms it into an X radiation. The anode (5; 33) comprises a plurality of elementary surfaces (7; 20; 34) whereof the normal lines (9; 38) are sequent. Each elementary surface receives the electron beam (4; 32).
