An array coil for 0.2 T reception has been developed for colon and heart studies in a FFC-MRI system. The array consists of 3 element posterior/anterior sections, with 16cm loops arranged in a “venn” pattern.
Minimizing conductor losses and noise figure over varying loading is particularly important in a low field system.
A two-turn litz arrangement was chosen offering good flexibility and Qu/Ql ratios. Interfacing electronics component topologies were simplified losses keping losses to a minimum. Matching, blocking, decoupling, and preamplification reside at element. Packaging is flexible textiles and substrates.
The resulting array conforms and retains performance with varying anatomy.
