Scanner reference database

これは何か

The scanner reference database is the comparison population and software context that turns a measured density into comparison scores.^[1,2]

なぜ重要か

T-score and Z-score are not raw density; they are comparisons against reference groups, so the reference context belongs in the graph.^[2]

どの判断に影響するか

• A report number may depend on site, scanner, software, and reference-population rules.^[1]
• This node helps separate measurement comparison mechanics from a direct statement about bone biology.^[2]

解釈上の注意

• BioConst does not convert scores across devices or assert that two reports are interchangeable.^[1]
