HATCH X-RAY Operating Manual
24
The Position Indicating Device (PID), also referred to as the Cone,
should be used to approximate the area of X-Ray exposure.
NOTE
The tube-head has an built-in focus to skin distance
of 9.05”(230mm) ± 0.2”(5mm). This is also referred
as short cone distance,which is the safe distance at
which the skin can be positioned.
Optionally, the operator can use long cone. Long cone
will increase the focus to skin position distance from
9”(229mm) to 12.20”(310mm) ± 0.2”(5mm).
4.3. Achieving the Best Image Quality
Hatch X-Ray is engineered to provide the best platform for dental radiographic
imaging. However the best results are obtained when the equipment is used the
right way. Practicing the following points will help the user make the best out of
the equipment’s output.
Patient’s Head Position
• Patient’s head should be as straight as possible.
• The patient should not move during the exposure.
Cone Position
• Cone should be positioned in such a way that the central axis of the cone
is perpendicular to the teeth and should be as close to the area being
imaged as possible.
• In general, the vertical angulation of the cone should be at +45° for
maxilla teeth and -10° for mandible teeth.
• The horizontal angulation of the cone should also be maintained to
achieve perpendicularity with respect to the teeth.
NOTE
The angle of the cone is indicated on the scale located on the
vertical joint of the tube head.
