14. QUALITY ASSURANCE
This section will occasionally use procedures described in previous sections.
Please refer to those sections when needed.
In order to assure image quality of the equipment, Quality Assurance (QA)
Phantoms will be provided (Reference 21CFR 1020.33 (d)(1)) to test of the
system performance and quality. These phantoms were designed to provide
maximum performance information with minimum effort.
During the installation or after a repair this QA procedure will create a
baseline performance data.
Make a periodic evaluation and compare with the baseline data.
If degradation in image quality or a change in QA values is noticed, contact
the Alliage Service Department.
For 2D images it will be validating the beam position, geometric calibration
and the maximum contrast resolution. The QA phantoms are show below.
QA Phantom for Panoramic* Resolution Test Phantom*
*Not included. Order on request
For 3D images, it will be validating six aspects of image quality

Contrast Scale

High Contrast Spatial Resolution

Low Contrast Detectability

Noise and Uniformity

Slice Thickness

Measuring Reference Material
The QA phantoms are show below.
