我们首次提出了一种完全MEMS集成技术，用于制造用于微尺度MRI应用的3D几何完美螺线管微线圈。我们报告25 μ m各向同性分辨率的磁共振图像的硫酸铜水幻影。这些图像是使用微线圈与5个绕组的绝缘25 μ m直径的Au线，并在工作频率（400 MHz）的品质因数高达46。
We present for the first time a fully MEMS-integrated technology to manufacture 3D geometrically perfect solenoidal microcoils for microscale MRI applications. We report 25 mu m isotropic resolution MR images of a copper sulfate aqueous phantom. These images are acquired using microcoils with 5 windings of insulated 25 mu m diameter Au wire and with quality factors as high as 46 at the operating frequency (400 MHz).
