The technique makes use of dual energy X-ray imaging, where overlapping tissue signals can be isolated and quantified by exploiting the change in X-rayattenuation at different energies.
这项技术通过双能X-射线成像，重叠的组织信号可以被隔离，并利用不同能量的X射线的改变衰减量化。

The attenuation of X-ray through the object is non-linear and the gray level of image is non-linear response of object thickness.
射线穿过物体的衰减是非线性的，经过影像系统得到的图像灰度与物体厚度是非线性的关系；

Some experimental results of in vivo observing X-rayattenuation of intra-tumor injection of indocyanine green are reported.
