fig 2.

Graph shows the relative SNR in units of the average SNR from the volume coils for the head and neck surface coil array (smooth lines); temporomandibular joint phased array coils (dotted-and-dashed line); and volume head and neck coils, which are the anterior neck coil (dashed line, ANC) and quadrature neck coil (dotted line, QNC). The SNR for the head and neck phased array and temporomandibular joint phased array were calculated from a region near the surface of the phantom (HNPA Edge and TJMPA Edge, respectively) and also from the center of the phantom for the head and neck phased array (HNPA Center). The SNR for the volume coils were calculated from regions near the center of the phantom for best uniformity
