2.1.2.2 Exposures
• Exposure
In this mode it is possible to check the unit tube head’s exposure
statistics.
The display shows the time and the date of the latest exposure, the
serial number of the unit and the exposure counters of the panoramic,
cephalometric, tomographic and 3D exposures. The total amount of
mAs, energy and exposure time are also shown.
• Panoramic DAP, Cephalostat DAP and 3D DAP
The patient’s radiation dose will be shown in a pop-up window after each
exposure. Radiation dose is indicated in terms of DAP (Dose Area
Product) and calculated separately for each exposure. The
measurement unit for DAP is milligray per square centimeter (mGy*cm²).
The DAP values are based directly to the measurements made from the
X-ray beam.
If you need to calibrate the DAP values which are shown in the pop-up
windows select the desired DAP on the Exposures display.
Use a DAP meter to measure the radiation dose and then compare the
measured dose (reading on DAP meter) with the calculated dose (value
shown in pop-up window). If the measured dose is lower than the
calculated dose, touch the left arrow to decrease the percentage value. If
the measured dose is higher than the calculated dose, touch the right
arrow to increase the percentage value. The setting can be adjusted
between 10% and 300%.
NOTE
You will have to calibrate DAP values separately for panoramic,
cephalometric and 3D exposures.
