中文摘要:
目的：在仅采用X线平片条件下实现对骨的局部区域进行三维测量。
方法：采用低速骨锯制作多层薄骨片，叠摞成螺旋阶梯，作为与临床实际拍摄对象最接近的标定块，测试了其厚度与X线灰度的相关关系。
结果：得到厚度与X线灰度的相关关系可用三次曲线拟合，并且在骨质厚度小于3.8 mm时，可以简化为线性拟合。
结论：借助本文骨性螺旋阶梯标定块，能实现通过X线平片灰度较精确地计算X线穿过的骨质厚度。 |

ABSTRACT
Objective: In order to get three dimensional measurements simply an plain X-ray photographs.
Methods: The multi-layers of bone pieces were made by use of bone saw,and piled up to spiral ladder, which was used as a calibrating module for to living bone in clinics. The relationship between the cortical thickness and gray level of the X-ray photographs was obtained.
Results: The correlation can be described with a cubic regression curve,and it can be simplified to a linear regression equation when cortical thickness is small than 3.8 mm.
Conclusion: It can be realized to get three dimensional measures of the bone on plain X-ray photographs,by use of the bony spiral ladder described here. |
