Abstract

Thermal neutron radiography and X-ray radiography are characterised by different penetration depths in various materials, for example in collagen and hydroxyapatite, two major components of bone. Neutron radiography penetrates hydroxyapatite easier than collagen and, conversely, in X-ray radiography attenuation is higher in hydroxyapatite than in collagen. This effect allows estimation of collagen presence in dry bone. In our study we show that differences between the two imaging methods are sufficient to produce significant results when bone areas with higher and lower content of collagen are being compared.

摘要

热中子射线照相术和X射线照相术的特点是在各种材料中具有不同的穿透深度，例如在骨骼的两个主要成分胶原蛋白和羟基磷灰石中。中子射线照相术比胶原蛋白更容易穿透羟基磷灰石，相反，在X射线照相术中，羟基磷灰石的衰减比胶原蛋白更高。这种效应可以估计干骨中胶原蛋白的存在。在我们的研究中，我们表明，当比较胶原蛋白含量较高和较低的骨区域时，这两种成像方法之间的差异足以产生显著的结果。
