High SNR imaging with internal coil detectors has been verified and numerous designs have been proposed. Prior work employing them has shown improvements in controlling MR-guided high intensity focused ultrasound and RF ablations. Here we present results from a phantom-experiment conducted in a 3 T GE scanner to investigate the merits of substituting the 8-channel array coil -typically used during Nd:YAG laser liver interstitial thermal therapies (LITTs)- with a flexible micro-coil integrated on a commercially available laser ablation catheter.
