【摘要】 随着核医学在核素显像、分子影像学、图像引导肿瘤放射治疗等方面的快速发展,核医学成像的教学开展在医学和核学等交叉学科方向的重要性越来越明显。但是,核医学成像的实践教学因为仪器昂贵、实验费用较高等特点,传统的实验教学主要以医院现场参观和实验室仿真训练为主,难以让学生真正动手进行实验并深入了解成像的全过程。通过自主开发核医学成像平台,核学院具备了在实验室开展实验教学的整套设备。该平台具有操作灵活、高分辨率、低成本的特点,由NIM电子学插件、32路PCI数据采集系统、光学平台、闪烁体/光电倍增管、64路uTCA数字化获取系统等组成。通过自行组装PET探头和SPECT探头,可以进行正电子发射断层成像和单光子发射断层成像,可开展模拟信号获取和全数字化数据获取,并开发有完整的图像重建软件。学生能够在老师帮助下,自主完成放射性核素点源和放射源模型等的数据获取和图像重建,进行真正的核医学成像实践训练,为后续工作和研究打好基础。更多还原

【Abstract】 Practical teaching guide is challenging in the course of nuclear medicine imaging,partially due to the very expensive facilities and the high costs of radiopharmaceutical.So while the usual practical training for students in nuclear medicine imaging mainly includes tour of PET/CT and SPECT/CT in hospital or virtual learning in front of computers,one thing is clear:practical training needs the experiences for student participants.Therefore,it is especially important that college should have a laboratory to launch student experiments by themselves.By developing a lab platform for nuclear imaging experiment,School of Nuclear Science and Technology has the equipment to train students’ practical and creative abilities.The imaging platform is made up of NIM modules,32_channel PCI DAQ,optical tables with orbital and linear translation stages,Scintillation crystals and PMTs,64_channel uTCA digital DAQ system.Students can setup PET modules and SPECT modules by themselves,take data at either analog or digital modes,and reconstruct PET and SPECT image.The student training should be guided under teachers,and the training program could be one or all of the imaging strategies of radionuclide sources,phantoms,plants,and small animals.更多还原
