关于一体化PET-MR机房设计实施方案的探讨

Scheme for simultaneous PET-MR room

目的 :通过合理布局、科学设计PET-MR机房,确保其屏蔽得当,避免对其他机器产生射频干扰,保障医护人员、患者及公众的身体健康。方法:根据省环保厅、全军检测中心和厂家的实际要求,合理选址,并充分考虑运输、承重、射线防护、射频屏蔽、磁屏蔽、通风、温湿度等要求,逐步实施。结果:机房承重满足PET-MR最大承重要求,射线防护达到本底辐射标准,射频屏蔽与磁屏蔽符合环保部门及厂家要求,接地电阻<2Ω,屏蔽房对地绝缘>1 000Ω,通风系统换气次数≥12次/h,机房温湿度控制在正常工作范围内。结论:PET-MR机房建设是一项复杂、庞大的系统工程,涉及多个环节,需要多个部门通力合作,严把质量关、材料关,认真检查机房建设过程中的不足,才能将PET-MR机房建设好。

Objective To design a simultaneous PET-MR room to eliminate the RF interference to other machines. Methods The requirements from the provincial environmental protection department, military test center of the PLA and the manufacturers were taken into accounts, with the considerations on transport, weight bearing, ray protection, RF shielding, magnetic shielding, ventilation, temperature, humidity and etc.Results The room met the requirements for weight bearing, ray protection, radio frequency shielding, magnetic shielding, temperature and humidity, with the grounding resistance less than 2 Ω, ground insulation more than I 000 1~ and the times for ventilation per hour not less than 12.Conclosion The construction of the integrated PET-MR room has to involve in multinle links anddepartments.
