摘　　要：目的:制作车载式核磁共振接收线圈,应用于突发灾害现场伤情相对复杂的人体部位外伤检诊,提供有效、简易线圈设备,快速定位诊断,正确判断伤情,满足车载式磁共振系统设备机动性强的基本要求。方法:应用3D打印技术中熔融沉积制造(fused deposition modeling,FDM)技术将聚乳酸(polylactic acid,PLA)加热熔化到半流体态,在计算机的控制下,根据所要轮廓信息,喷头将半流态材料挤压,凝固后形成轮廓状的薄层,最后进行固化,形成接收线圈。结果:利用3D打印技术制作完成符合人体主要部位需要的适合野外救援车载化条件(如头颈、肩、腰椎、膝关节等关键部位)的磁共振射频接收线圈,满足核磁医疗诊断需求。结论:3D打印技术可以满足车载式磁共振接收线圈的先期研发需求。Objective To manufacture a vehicle-mounted MR receiving coil for injury diagnosis in disaster relief.Methods Fused deposition manufacturing（FDM） method of 3D printing technology was used to make polylactic acid（PLA）into semi-fluid status, and the computer controlled the nozzle to extrude the semi-fluid PLA based on the contour information, then solidification occurred to form the coil. Results MR receiving coils were produced with 3D printing technology for the body parts of head and neck, shoulder, lumbar, knee joint and etc. Conclusion 3D printing technology can meet the requirements for the development of the vehicle-mounted MR receiving coil.
