A Monte Carlo calculation was carried out for boron neutron capture therapy (BNCT) of extra corporal liver phantom. The present paper describes the basis for a subsequent clinical application of the prompt gamma spectroscopy set-up aimed at in vivo monitoring of boron distribution. MCNP code was used first to validate the homogeneity in thermal neutron field in the liver phantom and simulate the gamma ray detection system (collimator and detector) in the treatment room. The gamma ray of 478 keV emitted by boron in small specific region can be detected and a mathematical formalism was used for the tomography image reconstruction.
对体外肝脏模型的硼中子俘获疗法（BNCT）进行了蒙特卡罗计算。本文描述了用于硼分布体内监测的瞬发伽马能谱装置后续临床应用的基础。首先使用MCNP代码验证肝脏模型中热中子场的均匀性，并模拟治疗室中的伽马射线检测系统（准直器和探测器）。可以检测到硼在小特定区域发射的478 keV伽马射线，并使用数学形式进行断层图像重建。
