For the multi-channels phased-array coils, overlapping
is commonly-used as a decoupling technique for loop-type
RF coils, but it not only imposes a new spatial
criterion but also limit the flexibility degree on
flexible application. Here we propose the idea of
annex-overlapping instead of traditional
loop-overlapping, apply the concept of Koch first-order
fractal-shape to deform the simple circular loop with
additional outstretching annexes. The MRI image results
of our prototypes of three-elements PA coils on a
flexible plastic sheet all demonstrated the ability of
simultaneous decoupling and flexibility against
deformation, provided the potential for mechanically
adjustable applications.
