While arrays of MRI coils can improve SNR and speed up acquisition time over single coils, most arrays today have a rigid structure, resulting in a poor fit and counteracting potential SNR gains. MRI resonant coil design has not kept pace with the new field of printed electronics which can pattern components directly on flexible substrates. In this project will extend these new techniques to print clothlike-MRI coils which will drape conformly over different body shapes, thus improving image quality for a wide patient base.

(d) We envision cloth-like flexible coils, which can either attach to clothing or form a tailored shirt for a tight fit for superior SNR.
