| 中文摘要: |
| 应用灰度对比法的原理建立了计算机X 线片蛋鸡骨放射密度法。结果表明, 铝阶厚度与灰度之间呈显著的线性关系
( P< 0. 01, r= 0. 997) , 铝阶厚度变化可准确反映蛋鸡骨骼骨量变化, 不同曝光条件对骨量值无明显的影响( p> 0. 05) 。该方法简
便, 精确, 重复性好, 经济, 为研究蛋鸡骨质疏松症提供重要的检测手段。 |
| 英文摘要: |
| The bone radiography density method with Computer - assisted X- ray film was established in layers according to
grayscale- contrast theory. The results showed that Aluminium wedge thickness had good linear relationship with its grayscale( P< 0. 01, r= 0.
997) , the change of Aluminium wedge thickness could reflect variation of bone volume exactly, different exposure parameters had not significant
effects on value of bone volume ( p> 0. 05) . This method plays an important role in the cage layer osteoporosis research, with convenient, accurate,
economical and good repetition. |
