肿瘤MRI引导质子治疗技术进展

随着MRI引导在光子束放疗中的应用推广,将实时MRI引导与质子束治疗相结合的理念逐渐受到重视,即MRI引导质子治疗(MRPT)。MRPT技术有望缓解质子治疗过程中不确定性问题,发挥质子的物理优势。然而,由于质子治疗和MRI引导系统之间存在多重电磁相互作用,这导致两套系统相互影响。笔者对MRPT系统的研究进展进行综述,为MRPT系统设计提供一定的参考。

Research progress on magnetic resonance imaging-guided proton therapy for tumors

With the application of magnetic resonance imaging (MRI)-guided photon therapy, the concept of combining real-time MRI guidance with proton therapy, namely, MRI-guided proton therapy (MRPT), has attracted widespread attention. It is expected that MRPT canmitigate the uncertaintiesduring the treatment of proton therapy to make full use of the physical advantages of protons. However, multiple electromagnetic interactions between proton therapy and MRI-guided systems may lead to mutual interference between the two systems. This article review the research progress on the MRPT system, aiming to provide certain reference for the design of MRPT system.
