ABSTRACT:
In an ultrasonic inspection method and apparatus for inspecting the presence or absence of a defect in an object to be inspected by receiving as an RF signal a reflection beam of an ultrasonic beam emitted from a probe to the object and displaying data of the RF signal on a display unit, a maximum value indicative of a positive peak of the RF signal is detected, a maximum absolute value indicative of a negative peak of the RF signal is detected, a computation is performed for comparing in magnitude the maximum value indicative of the positive peak with the maximum absolute value indicative of the negative peak, and a computed value is displayed on the display unit so that the presence or absence of a phase inversion of the RF signal may be judged for deciding the presence or absence of a defect in the object.
