High X-ray doses prescribed for radiosurgery must be delivered with sub-millimetre precision to avoid damaging nearby organs and healthy tissue.
放射外科所用高能X射线必须提供毫米以下精度的能量传输才能避免损伤周围器官和健康组织。

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-ray attenuation 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。

Traditional CT has a great limitation because its image is produced based on the X-ray absorbed by human tissue.
