4 CHANGING THE TUBE HEAD

a) Remove the front cover of the tube head by unscrewing the 4 fixing screws at the back side.
b) Remove the front cover of the tube head.
c) Remove the back cover of the tube head by unscrewing the 2 fixing screws that can be seen
after removing the front cover
d) Remove the secondary collimator cover by unscrewing the 4 screws at the cassette head.
e) Tilt the tube head end of the cover downwards and the other end will be released. Be careful
not to drop the cover on the collimator.
Remove the primary collimator mechanism from the old tube head.
f) Remove the damaged tube head out from the X-ray unit. Then position the new tube head to
the X-ray unit.
g) Reconnect all the cables, except fan cables (you don't need to replace the covers yet).
h) Initialize the tube head as described in section 3.9 "Tube type programming" on page B-14.
i) Check and adjust the radiation field. This procedure is described in section 2 "PANORAMIC
X-RAY BEAM ADJUSTMENT" on page D-4.
NOTE If the first slot is adjusted mechanically by loosening the screws and turning the tube
head so that the beam is aligned in the middle, normally the other slots need no or only
a small adjustment.
Make the ball phantom test picture. Adjust if necessary (see section 3 "PATIENT POSITION-
ING MECHANISM" on page D-11).
Install the covers.
