本研究介绍了 LEPTS，这是一个逐事件蒙特卡罗程序，用于模拟与眼部肿瘤近距离治疗相关的眼科 Ru-106/Rh-106 施药器。该代码的显着特征是区分弹性碰撞和几种非弹性碰撞的潜在辐射-物质相互作用模型，以及主要使用实验输入数据。特别强调低能电子的处理，因为低能电子通常负责沉积传递给物质的总能量的很大一部分。 (C) 2011 Elsevier Ltd. 保留所有权利。
The present study introduces LEPTS, an event-by-event Monte Carlo programme, for simulating an ophthalmic Ru-106/Rh-106 applicator relevant in brachytherapy of ocular tumours. The distinctive characteristics of this code are the underlying radiation-matter interaction models that distinguish elastic and several kinds of inelastic collisions, as well as the use of mostly experimental input data. Special emphasis is placed on the treatment of low-energy electrons for generally being responsible for the deposition of a large portion of the total energy imparted to matter.
