Application of holographic interferometric studies of underwater shock-wave focusing to medicine

摘要

Abstract: phic interferometric flow visualization wassuccessfully applied to underwater shock wave focusingand its application to extracorporeal shock wavelithotripsy (ESWL). Real time diffuse hologramsrevealed the shock wave focusing process in anellipsoidal reflector made from PMMA and doubleexposure holographic interferometry also clarifiedquantitatively the shock focusing process.Disintegration of urinary tract stones and gallbladderstones was observed by high speed photogrammetry.Tissue damage associated with the ESWL treatment isdiscussed in some detail. !8
