Ex-vivo and in-vivo measurements were performed with a newly developed intra-oral flexible coil for improved SNR and delineation of the dental root canals.
Figure 3: Comparison
of SNR and root canal visibility between the 32ch head coil (left), LC4 (center)
and IFC coupled inductively to LC4 (right).
Figure 2: Ex-vivo
measurements of a phantom show SNR gain of 6 with the inductively-coupled coil
(IFC) in comparison to solely using the 4cm loop coil by Siemens (LC4).
