4.7 Exposure Techniques
As an intra-oral dental X-ray system, the NOMAD Pro 2 can be easily positioned. This
high degree of flexibility makes it easy to take exposures while the patient is reclined, lying
completely on their back, or sitting upright. Ensure the patient is protected by using an
apron.
When taking images, operators may hold the
NOMAD Pro 2 by having both hands on the handset
grip, or, for increased stability and patient safety, by
placing one on the grip and the other on the underside
of the housing.
Position the NOMAD Pro 2 relative to the imaging
system to minimise cone-cutting. (If your practice uses
film holding kits or aiming devices, check compatibility
in advance.)
Exposure times increase proportionally when the
imaging angles vary away from 90° (or perpendicular)
to the film or sensor. To maintain low patient X-ray
doses and to keep the operator within the protection
zone, have the head of the patient slightly tilted, and/
or raise or lower the chin as needed. (See Section 2.1
Radiation Safety.)
When the device must be angled and the operator
cannot be completely within the protection zone,
ensure operator protection through the use of proper
safety measures, such as the use of an apron. (See
Section 2.1 Radiation Safety.)
Avoid touching the patient with the cone or
backscatter shield; disposable plastic coverings can be
used to prevent cross-contamination.
Determine what NOMAD Pro 2 exposure time
settings deliver optimal results for the type of imaging
(digital or film-based) that is used on a regular basis.
NOTE: Both digital imaging sensors and film speeds
can vary somewhat in their characteristics and could
require different exposure settings to meet density
preference. (See Section 4.10 Settings Menu for more
information.)
