In a conformal and inverse modulate intensity radiation planning (IMRT), mechanical collision is a key problem, which determines whether the therapy planning can be really executed or not.

在适形和逆向调强放射治疗中，机械碰撞问题是一个治疗计划的物理可实现性的基本问题。

Given the risks of aiming such a powerful beam of high-intensity radiation at an Earth ground station, as well as the cost of building billions of dollars in infrastructure to collect the energy in space, the efficiencies you can get from terrestrial solar power seem a safer bet--at least for now.

FORBES: Galactic Gold Mine?

In recent years instrument makers have refined the therapy further with a technique called Intensity Modulated Radiation Therapy.

However, satellites are shielded from that radiation, and the intensity of the radiation in the inner belt is relatively stable.
