The length of microstrip transceiver arrays is often
constrained by the required resonant frequency, limiting
the image coverage. To increase the imaging coverage and
also improve its parallel imaging capability, we
designed, constructed and tested a 16-channel double-row
microstrip transceiver array for human head imaging at
7T. In the comparison study with a regular single-row
array, the double-row array demonstrated a larger
imaging coverage along z-direction and improved parallel
imaging capability. The proposed technique is
particularly suitable for the design of large-sized
transceiver arrays with large channel counts.
