磁共振成像(MRI)集成诊疗设备屏蔽技术分析

摘要/Abstract

摘要： 磁共振成像(MRI)是现代医学诊断的关键技术,以其高解析度和对软组织的优良对比度著称。近年来,MRI技术与其他诊疗设备的集成,例如PET、SPECT、ECG、EEG以及放射治疗设备如直线加速器和质子治疗加速器,显著提升了诊断和治疗的精准性和效率。本文讨论了这些集成技术的屏蔽设计和要求,包括技术上的磁屏蔽和辐射屏蔽以及方式上的设备自身屏蔽和机房环境的屏蔽;介绍了集成设备自身屏蔽要求和影响因素,同时提出集成设备的屏蔽技术不是简单的磁屏蔽加辐射屏蔽的“1+1”模式,而是存在着一定的协同作用。

Abstract: Magnetic Resonance Imaging (MRI) is a pivotal technology in modern medical diagnostics, renowned for its high resolution and excellent contrast of soft tissues. In recent years, the integration of MRI technology with other diagnostic and therapeutic devices, such as Positron Emission Tomography (PET), Single Photon Emission Computed Tomography (SPECT), Electrocardiography (ECG), Electroencephalography (EEG), and radiation therapy equipment like linear accelerators and proton therapy accelerators, has significantly enhanced the precision and efficiency of diagnostics and treatments. This paper discusses the shielding design and requirements for these integrated technologies, including technical aspects of magnetic and radiation shielding, as well as methodological approaches for both the equipment’s own shielding and the shielding of the room environment. This paper also introduces the shielding requirements and influencing factors for the integrated equipment itself, and also proposes that the shielding technology for integrated equipment is not a simple “1+1” model of magnetic shielding plus radiation shielding, but rather some certain synergistic effect involved.

Key words: integrated technologies, MRI, shield design, diagnostic devices
