shall be maintained in all X-ray rooms and will contain
the following information:
Column 1:
Patient's Name
Column 2:
Patient's SSN
Column 3:
Patient's Unit
Column 4:
Rank/Rate/Retired/Dependent/etc.
Column 5:
Number of X-ray exposures and
type: bitewing, periapical, occlusal,
panograph
Column 6:
kVp, mA, exposure time
Column 7:
Reason retake X-ray required (if
applicable)
When stating the reason for a retake X-ray, be
specific on the nature of the retake, for example:
conecut, elongated, foreshortened, dark image, etc.
DENTAL X-RAY MACHINES
The most commonly used X-ray machine is the
wall-mounted dental X-ray unit (fig. 1-2). Because the
basic components and operating techniques of all
dental X-ray machines are similar, we will only discuss
the wall-mounted unit. The component parts of the
wall-mounted machine discussed here are the tube
head, cylinder, extension arm, ready light, and a
separate control panel.
TUBE HEAD
The tube head (fig. 1-3) contains the X-ray tube
and other components necessary for generating X-rays.
When an exposure is made, X-rays pass through an
aluminum filter that screens out unnecessary radiation.
Angulation scales are on both sides of the tube head for
precise positioning technique.
CYLINDER
The cylinder (or cone) is affixed to the tube head
and is used to align the tube head with the patient and
the X-ray film. It is open-ended and composed of lead
laminated material that establishes the minimum
distance from the X-ray source to the patient’s skin.
