A proof of principle for a truly modular ultra-lightweight
multi-purpose flexible receive array made from coaxial coil elements was
demonstrated by showing three 4-channel modules arranged in different array
configurations.
Fig. 1: 4-ch coaxial coil module. The compact cylindrical housing (diameter
= 5.2 cm, height 3.2 cm) surrounds the PCBs with all electrical components and four
preamplifiers.
Fig. 2: a)
Differently arranged 12-ch layouts built from the same modules M1, M2 and M3. b) MR images (GRE2D) acquired on a flat
phantom in a slice at a distance of 5 cm to the coil arrays. The distance from
the arrays to the phantom is around 5 mm.
