摘要/Abstract

摘要： 总结并分析了现有用于评估颌骨密度的四种最常用的方法及不足，提出了用于口腔锥束CT的基于K₂HPO₄液体体模的定量CT方法，并说明了具体的测量方法.同时对K₂HPO₄液体体模进行了均匀性与线性度测试、稳定性测试以及与固体体模的对照测试.测试结果表明在口腔锥束CT下基于K₂HPO₄液体体模的骨密度测量结果与常规CT下基于固体体模的测量结果等效.同时液体体模制作成本低，配置方便灵活，该方法值得临床推广和使用.

Abstract: The current four most commonly used methods to evaluate the jaw bone mineral density was summarized， and the shortage of these methods was analyzed. Quantitative computed tomography (QCT) method was proposed and used for oral cone beam CT (CBCT) based on K₂HPO₄ liquid phantoms， and specific measurement method was described. Meanwhile the K₂HPO₄ liquid phantoms uniformity， the linearity， and the stability were tested， and were contrasted with the solid phantoms. The test results showed that the CBCT bone density measurement results based on K₂HPO₄ liquid phantoms were equivalent with the results of the conventional CT based on solid phantoms. Meanwhile， in view of the low production costs， convenient and flexible configuration， this method was worthy of clinical promotion and application.

Key words: CBCT, QCT method, jaw bone mineral density, K₂HPO₄liquid phantoms, Ca₅OH(PO)₄ solid phantoms
