For the compression thickness indicator test in mammography QC, which paddle is used?

Explanation:
The test checks that the mammography system’s display of breast thickness under compression is accurate, which matters for proper exposure and image quality. To evaluate this reliably, you need a small, defined area of compression so the thickness readout can be checked against a known value. The spot compression paddle is designed for exactly this purpose, providing localized compression that yields a controlled thickness reading for the indicator. A standard compression paddle would compress a larger area and isn’t suitable for validating the thickness readout, and the other paddle options aren’t used in this QC test. In short, the spot compression paddle is the appropriate tool to verify the compression thickness indicator.
