The compression thickness indicator QC performance criteria must be accurate to what tolerance?

The test is about how accurately the compression thickness indicator reflects the actual breast thickness under compression. The standard tolerance is plus or minus 0.5 cm. This keeps the indicated thickness close enough to reality so that dose estimates, compression reproducibility, and image quality stay consistent across exams. A looser tolerance (like ±1.0 cm or ±2.0 cm) could mask meaningful differences in compression, while a tighter tolerance (such as ±0.1 cm) would be unnecessarily difficult to achieve in routine practice.
