An MRI RF coil that is optimized for SENSE imaging is used in a method
where the surface current density distribution on a coil former was
calculated to maximize the SNR.sub.sense within a volume of interest. An
analytic relationship was formulated between the SNR.sub.sense and
surface current density on the coil former. The SNR at pixel .rho. in a
SENSE-MR image, SNR.sub.sense,.rho., is inversely proportional to the
g-factor The g-factor was formulated in terms of the B1 distribution of
the coils. By specifying the geometry of the desired coil former and
using a finite element mesh, the surface current distribution was
calculated to maximize the SNR.sub.sense, by minimizing (1/SNR.sub.sense)
in the volume of interest using a least squares procedure. A simple
two-coil array was tested and phantom images were collected. The results
show that the new coil design method yielded better uniformity and SNR
compared to standard coils.
