A multi-purpose coil arrangement incorporating a small loop coil and a position-adjustable add-on saddle coil is proposed to enhance the imaging coverage of anatomical images and improve the SNR in the regions distant to the surface coil.
The design of small surface coil (a), saddle coil (b) and surface coil combined with the saddle coil (c and d). The diameter of all copper wires is 1 mm.
(a) The position of 12 selected ROI overlaid on T2WIs using small surface coil only (left) and proposed coil (right) respectively. One group of ROIs (1 to 4) is located at regions close surface coil, another group (5 to 8) is located at regions with middle distance from surface coil and the other group of ROIs (9 to 12) is at regions with farthest distance from surface coil. (b) The SNR results from 12 ROIs using small surface coil only and proposed coil respectively.
