摘要
多种模态影像特性的融合将极大地提升肿瘤与正常组织的识别度,多模态影像的引导已成为开展精确放疗的一个不可或缺的环节。得益于国产医疗设备的发展,很多基层医院已具备基于国产设备开展多模态影像引导的放射治疗的基础。本文将针对四川省人民医院医联体基层成员单位的国产放疗系统与国产核磁共振成像(Nuclear Magnetic Resonance Imaging,MRI)影像系统在开展多模态影像引导放疗时的不兼容问题,提出一种解决方案。本文的经验将为基层单位的同行提供经验参照,为相关国产设备的进一步研发提供临床一线的反馈。
[Background]The fusion of multi-modal imaging characteristics will greatly improve the recognition of tumors and normal tissues.The guidance of multi-modal imaging has become an indispensable link for precise radiotherapy.Benefiting from the development of domestic medical equipment,many grassroots hospitals have the basic conditions to carry out multi-modal image-guided radiotherapy based on domestic equipment.The incompatibility between the domestic radiotherapy system and the domestic magnetic resonance imaging(MRI)imaging system affects the integration of multimodal image-guided radiotherapy.[Purpose]This study aims to solve the problem of incompatibility of multi-modal image fusion in radiotherapy,provide experience reference for counterparts in grassroots units.[Methods]First of all,the imported radiotherapy planning system(Eclipse TPS System)and imaging system(SIEMENS Magnetom aera 1.5 T)were taken as reference,a calibration software tool MagicPhantom was independently developed by using Python programming language.Then an image correction links in the clinical process of the domestic radiotherapy planning system(FonicsPlan)and MagicPhantom was added for the review of multimodal images.Finally,the multi-modal image-guided precise radiotherapy in the application scenarios of national production equipment was implemented.[Results]The newly-added image review process takes approximately 2 min to process images of each case,which effectively solves the problem of incompatibility between domestic radiotherapy system and domestic imaging system.[Conclusions]Using Python programming language to solve the problem of incompatibility of multi-modal image fusion is a simple and feasible method,which will help provide experience reference for peers in the grassroots units,and help manufacturers to better improve equipment performance and complete product iteration.
