Surface coil resonators have been widely used to perform topical EPR spectroscopy. They are usually positioned adjacent to or implanted within the body. For EPR applications these resonators have a number of important advantages over other resonator designs due to their ease of sample accessibility,

## Abstract For a birdcage coil with elliptical cross‐section, a sinusoidal current pattern does not provide a homogeneous B~1~ field. A simple theory was developed to create an optimized current distribution for elliptical birdcage coils. This optimized current pattern can create a perfectly homog
## Abstract ## Purpose To evaluate the B1 field uniformity of a double‐tuned birdcage coil designed for ^31^P/^1^H MRI/MRS spin‐echo (SE) imaging of the metatarsal head region of the foot in neuropathic diabetic patients. ## Materials and Methods A low‐pass double‐tuned ^31^P/^1^H RF birdcage co
