The bone density of the mandibular angle and coxofemoral region can be measured with dual-energy X-ray absorptiometer.
可以使用双能 X 射线吸收仪测量下颌角和股骨区的骨密度。

Since liquid blood and the vessels are not very dense, a contrast with high density (like the large iodine atoms) is used to view the vessels under X-ray.
由于液体血液和血管是不是很密集，高密度的对比(如大量的碘原子)是用来查看X射线下的船只。
