Article Snippet: Fig. 5 Comparison of acoustic performance of conventional and pre-snapback modes. a Schematic of the wire imaging setup using the Verasonics Vantage 128 system. b Wire image obtained under conventional and pre-snapback modes. c Comparison of imaging intensity at a depth of 7 mm in conventional and pre-snapback modes. d Imaging intensity as a function of depth for conventional and pre-snapback modes Additionally, the high loop gain of the pre-snapback mode enabled detection of deeper signals, with a 5.1-fold stronger signal observed at a depth of 45 mm, allowing for distinct visual identification (Fig. ).
