A method of fabricating a liquid metal radio-frequency (RF) coil assembly of a magnetic resonance (MR) system using a sewing machine is provided. The method includes providing a sewing accessory assembly, the sewing accessory assembly including a substrate holder and a presser foot. The method also includes attaching the presser foot with a sewing machine, positioning the substrate holder containing a first substrate underneath a needle arm of the sewing machine, and carving a pattern of grooves on a surface of the first substrate using the presser foot by operating the sewing machine. The method further includes forming RF coil loops by depositing liquid metal in the grooves and applying a second substrate over the RF coil loops.

Open peripheral vascular coil and method of providing peripheral vascular imaging

A method and apparatus is disclosed to analogically combine MR signals from RF coils to form multiple sets of analogically combined MR signals, and then digitally combine the analogically combined sets of MR signals to provide a digitized signal set for image reconstruction. The analogical combining followed by the digital combining of acquired MR signals improves intrinsic SNR of the RF coils used for data acquisition from a field-of-view (FOV) without compromising FOV for simultaneous MR data acquisition.
