• Anodic current 7 mA.
• Source to Detector Distance SSD = 250 mm (10 inches)
• Total (inherent) filtration 2 mm Al equip.
Unless the image is grossly over- or under-exposed, image density can be corrected by sub-
sequent software processing (contrast/brightness — see Imaging Software User Manual and
Installation Guide).
1 One impulse is equal to .017 sec. at 60 Hz. The recommended number of impulses can be
adjusted as necessary for proper exposure, resulting in adequate image density and contrast
and low noise gratuity.
Panoramic/cephalometric equipment
The DenOptix QST system requires no adjustments to the panoramic/cephalometric exposure
settings (kV, mA or time). The DenOptix QST system can be used with almost any existing
panoramic/cephalometric unit, regardless of age or manufacturer.
The use of a cassette without an intensifying screen is highly recommended. If you choose
to use a cassette with an intensifying screen, you must at a minimum remove the front
screen. If the intensifying screens are not removed, you will get a low quality image due
to the shielding effect from a decreased dose reaching the imaging plate. To remove the
intensifying screens, follow the directions below.
