Abstract
Body-mounted ultrasonography stability is critical, as transducer displacement creates RF data artifacts. We quantify mounting stability by analyzing superficial RF signals. Frame-by-frame RF differences were quantified via RMS, defining Instability Waveforms (IW) and depth profiles. Waveforms varied with depth and mounting, exhibiting various intensities and regularities, in some cases showing periodicity, potentially from vessel pulsation. A consolidated superficial IW index could be indicative of optimal mounting, improving artifact-free detection of endogenous tissue dynamics.
