Published: June 2010

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 microm isotropic resolution MR images of a copper sulfate aqueous phantom. These images are acquired using microcoils with 5 windings of insulated 25 microm diameter Au wire and with quality factors as high as 46 at the operating frequency (400 MHz).
