摘要

通常，利用高能和低能x射线图像可以分解为软组织图像和骨骼图像。这是基于不同的材料具有不同的高能x射线与低能x射线的衰减系数比。我们将这一原理应用于平均原子序数不同的软组织中不同的材料，可以进一步分离不同组织的图像，如肺组织和结缔组织，如支气管。该方法已被实验证明，对软组织成分的鉴别具有潜在的应用价值。

Multiple decomposition technique for dual energy x-ray image

Usually, using high and low energy x-ray images we can decompose into soft tissue image and bone image. That is based on that different materials have different attenuation coefficient ratios of high energy x-ray to low energy x-ray. We apply this principle to different materials in soft tissues with different average atomic number, it can further separate image of different tissues such as lung tissue and connective tissue like bronchus. This method has been proved by experiment and it has potential use for identifying the composition of soft tissues.
