In Vivo Verification of Proton Therapy: Derivation of Delivered Radiation Dose via Prompt Gamma Imaging.

传统的放射疗法使用高能辐射束来破坏癌细胞。这些光束不是局部的，并且可以影响周围组织。常见的副作用包括恶心，有时会破坏器官功能。质子治疗是一种替代治疗方法，它使用质子束，能够更好地局部靶向特定区域。作为一种治疗方法，它们不会以同样的方式影响患者，几乎没有明显的副作用。

Conventional radiation therapy uses high energy beams of radiation to destroy cancerous cells. These beams are not local and can affect the surrounding tissue. Common side-effects of this include nausea and sometimes disruption to organ function. Proton therapy is an alternative treatment that uses proton beams that are better able to locally target specific areas. As a treatment, they do not affect the patient in the same way, with little to no noticeable side-effects.
