讨论了激光等离子体作为高能离子源用于质子治疗的可行性。这一提议是基于最近实验室中观察到的有效离子加速以及关于高功率激光辐射与气体和固体目标相互作用的数值实验。生物组织中质子能量损失的特殊依赖性(布拉格峰)促进了放射治疗的主要问题之一的解决，即以足够强和均匀的剂量照射恶性肿瘤，确保对周围健康组织和器官的照射最小。在提出的方案中，一束由激光脉冲加速的快离子束可以集成到用于质子治疗的装置中。(C)2002年Maik“NAUKA/INTERPERIONAL”
The feasibility of using laser plasma as a source of high-energy ions for the purposes of proton therapy is discussed. The proposal is based on the efficient ion acceleration observed in recent laboratory and numerical experiments on the interaction of high-power laser radiation with gaseous and solid targets. The specific dependence of proton energy losses in biological tissues (the Bragg peak) promotes the solution of one of the main problems of radiation therapy, namely, the irradiation of a malignant tumor with a sufficiently strong and homogeneous dose, ensuring that the irradiation of the surrounding healthy tissues and organs is minimal. In the scheme proposed, a beam of fast ions accelerated by a laser pulse can be integrated in the installations intended for proton therapy. (C) 2002 MAIK "Nauka/Interperiodica".
