Abstract

Изменение поверхности стенки обнаруживается за счет передачи импульса входных ультразвуковых колебаний на проксимальную поверхность стенки и дальнейшего приема ультразвуковых колебаний от этой проксимальной поверхности. Принятые ультразвуковые колебания сравниваются с ранее обнаруженным импульсом выходных ультразвуковых колебаний, которые были приняты от проксимальной поверхности для того, чтобы идентифицировать, например, время прихода текущего импульса выходных ультразвуковых колебаний. Время прихода этого текущего импульса выходных ультразвуковых колебаний можно использовать для обнаружения изменения поверхности стенки, такого как изменение толщины стенки. Другие варианты осуществления позволяют обнаружить изменение профиля шероховатости стенки с использованием изменений в принятых ультразвуковых колебаниях, отличных от времени прихода.
