  We looked for a biological analogy to developed an improved surface coil to
acquire magnetic resonance images. Nature offers engineering solutions that can
be exploited to improve the performance of devices, such as MRI RF coils. In
this paper, we proposed a coil layout based on flower petal patterns for UHF
MRI at 15.2 T. This particular configuration offers the possibility to use a
different number of petals and shapes. The petal resonator coil and the
magnetron coil have similar layouts, which have proved to outperform the
popular circular coil. Phantom images were acquired with our coil prototype to
demonstrate it feasibility. These phantom images show no image degradation
caused by the mutual inductance of the adjacent petals in both orientations.
The SNR was also calculated using the image data and giving 31.16. Phantom
images showed the coil viability and compatibility with conventional pulse
sequences at 15.2 T. It still remains to investigate whether this bio-inspired
surface coil is able to outperformed the popular circular coil.
