引言

磁粒子成像是新一代生物医学成像技术，基于磁粒子作为示踪剂，利用其非线性磁化响应信号，具

有高灵敏度、高特异性、高时空分辨率、无辐射且无成像深度限制等优势，在国内外均得到了快速的发

展和应用，且已展现出一定的技术积累和应用潜力。目前，该技术已经在检测深层微小肿瘤、植介入血

管成像、在体细胞示踪、实时动态血流监测、脑卒中和脑损伤检测、肺灌注成像等多领域开展预临床研

究，被证明在临床上具有广泛的应用前景。

磁粒子成像设备激励系统的工作参数直接决定设备工作性能，影响成像质量，最终关乎到诊断检

查结果的准确性。磁粒子成像设备工作激励系统工作参数是设备性能的核心要素，这些参数的设定直

接关系到成像质量，进一步影响诊断结果的准确性。然而磁粒子成像设备激励系统的评价和规范方

面，目前尚无统一的标准和定量的指标。因此对磁粒子成像设备激励系统工作参数进行评定和相关指

标的定量分析，形成统一标准，具有重要意义。

本文件制定通用要求，以规范磁粒子成像设备激励系统的研发与质量评估，推动磁粒子成像技术

的高质量发展。
