Purpose To introduce a selfmade solid calibration phantom for bone mineral density(BMD)measurement with quantitative CT(QCT).
目的报告一种自制骨矿密度CT测量固体标准件。
Based on physical phantom after 100 times data iteration, the measurement accuracy of this system for small and large signal is 1.0% and 0.1%.
该系统基于物理模型的测量数据经100次迭加后，测量精度在小信号时为1.0%，大信号时为0.1%。
It is displayed that QCT with selfmade phantom can be used clinically, easy operated and have accuracy measurement.
与国内外的报道基本相同。这表明本方法在临床上是可行的，操作方便和测量准确性较高。
