From: Steerable needles for radio-frequency ablation in cirrhotic livers
Illustration of insertion depth and needle deflection (A), and summary of deflection data (B) for punctures in fresh, cirrhotic liver explants (A), using the RFA probe and steerable needle v2, along straight and curved paths. Also shown are summary boxplots and individual data points (C) of histological tissue damage (mm2) after the insertions. The asterisks indicate Wilcoxon rank sum test differences (α = 0.05).
