2. DESCRIPTION OF THE SYSTEM
2.1. DESCRIPTION OF THE X-RAY DEVICE
Description des différentes parties :
a X-ray generator.
Depending on the operating mode, the high frequency
constant potential
x-ray generator works at 60KV 7ma (En60 mode,
63KV 6ma
(En63 mode) or 65KV 6ma (En65 mode).
The generator can turn on a horizontal plane
endlessly; on the other
hand, as far as vertical movement is concerned,
rotation is limited
upwards by a mechanical end-stop..
b - Movable collimator (cone).
The generator can work with different types of
collimators that are automatically recognized:
• 8” ROUND COLLIMATOR (incorporated in the
generator): minimum
skin/focus distance 20 cm and 60 mm output
beam
• REMOVABLE 12” round CONE: minimum
source/skin distance
30cm and diameter of x-ray beam exiting cone
55mm (with cone attached).
c - Focus spot.
d - Double pantograph arm.
e - Extension arm.
The extension is available in three lengths: 40 cm, 60
cm and 90 cm
f - Handheld.
he handheld can be placed either near the control unit
or in a remote
position. As a result, the doctor can move
conveniently around the
room and move out of the area where x-rays are
emitted.

2.2. OPERATING GUIDELINES
The Revolution 4DC can function in different modes (MULTIMODE technology):
1) En60 operating mode
X-ray emission at 60KV and 7ma. The x-ray unit automatically calculates the best exposure time (from 0.01s to
1.00s) based on the selected tooth and patient size.
2) En63 operating mode
X-ray emission at 63KV and 6ma. The x-ray unit automatically calculates the best exposure time (from 0.01s to
1.00s) based on the selected tooth and patient size.
3) En65 operating mode
X-ray emission at 65KV and 6ma. The x-ray unit automatically calculates the best exposure time (from 0.01s to
1.00s) based on the selected tooth and patient size.
4) AUTO operating mode
The x-ray unit automatically suggests the best operating mode (En60, En63 o En65) and exposure time (from
0.01s to 1.00s) based on the selected tooth and patient size.
The suggested exposure time can be corrected from the handheld.
In addition, the x-ray unit has a special USER mode that can be set by the user. The user can select the best
combination of load factors (operating mode and exposure time) for each tooth and patient size.
