DEXIS Titanium

X-ray Dose / Exposure Time Settings

The DEXIS Titanium sensor has been designed to be used with a wide range
of dose settings between 20 uGy and 2,000 uGy, to allow adjustments of the
dose to the specific diagnostic task, and to compensate for under- and over-
exposure. As a general recommendation, start by using dose / exposure time
settings recommended by your X-ray source manufacturer for digital X-ray
sensors.
The DEXIS Titanium sensor can be used with much lower dose / exposure time
settings than radiographic film. Nevertheless, low dose operation of a digital
sensor in general can result in a grainy image appearance. If the image of the
DEXIS Titanium sensor appears grainy, increase the dose settings. If you
obtain good results with a particular setting, you might try a lower dose setting
to see if you still gain good results.
The DEXIS Titanium sensor can work at higher dose /exposure time settings, if
needed for a particular diagnostic task. At high dose / exposure time settings, it
might not be possible to distinguish air from soft tissue. Such regions may
appear overexposed. If air and soft tissue regions in the image appear
overexposed, reduce the dose settings.
Remember, as with standard film, you will need to adjust the duration setting to
compensate for tooth type (central incisor to molar) and patient body type
(larger adult to small child). Ultimately, the settings you choose should be what
you consider to be suitable for your diagnostic needs.

X-ray Sharpness / Contrast

Many parts of the X-ray imaging system contribute to the sharpness and
contrast of the image. It is recommended that you use a dental phantom for a
periodic (at least annual) assessment of the image quality by performing a side-
by-side comparison of an initial dental phantom image to a current dental
phantom image to ensure that the images have sufficient quality for diagnostic
purposes in your application.
Dental phantom images should be acquired with fixed settings for X-ray dose
(kV, mA, distance), and a fixed and reproducible alignment of the X-ray source
and the dental phantom to the DEXIS Titanium sensor.
NOTE: Contact DEXIS technical support for recommendations about
commercially available dental phantoms.

Display Image

Refer to the software manual for guidance on how to ensure good display
settings and image display properties. It is recommended to view images on a
factory calibrated LCD/LED monitor with at least 2,560 x 1,440 pixel resolution
at 0.25 to 0.26 dot pitch or better and 32bit true color, in native resolution.
