Recently, we developed a simple novel technique for EUS-guided portal pressure gradient (PPG) measurement (PPGM). Our animal studies showed excellent correlation between EUS-PPGM and interventional radiology-acquired PPGM. In this video we demonstrate the results of the first human pilot study of...

The amplitude of generated piezoelectric voltage and power depends on the device's working frequency, as well as the value of induced strain. The first resonance frequency (f r) of a cantilever is the lowest vibrational mode, exhibiting the highest achievable strain and displacement. The goal of...
