12 3D quality control
A quality control test must be carried out on the X-ray unit once a month
in order to ensure consistent image quality. It is recommended to compare
the test results to the results from the previous month's test to notice any
significant changes that may have occurred. Quality control tests are carried
out using a separate software called Device Tool QA, that is installed on
your computer for this purpose.
The following sections provide instructions on how to run 3D Quality
Assurance (QA) tests for Planmeca Viso 3D X-ray units.
NOTE
The instructions in the following sections are valid only for Planmeca QA
tests. The instructions for DIN 6868 based QA tests (used in Germany) are
given in a separate manual.
NOTE
The Reconstruction PC must be switched on and the TCP/IP connection
must work.
12.1 Safety notices and compatibility
CAUTION
Only qualified service technicians may perform QA testing using the full
Planmeca Device Tool installation. If performing the QA test using the
Device Tool QA program, read this section carefully before proceeding.
CAUTION
In the Device Tool, for the Planmeca 3D QA, it is possible to run multiple
calibrations, i.e. select all 3D QA calibrations to be run in a row. If the
multiple calibration is used, be extra careful with the following issues:
•
The X-ray unit arms will move and radiation is generated during the
calibrations.
• Take adequate protection measures.
• Do not leave the X-ray unit unattended while the calibrations are running.
The Device Tool displays a confirmation when the grouped calibration is
started.
NOTE
The display values and user interface images shown in this chapter are only
examples and should not be interpreted as recommended values unless
otherwise stated.
The 3D QA testing described in this chapter is valid for Planmeca Viso X-ray
units.
