    摘要: A method of determining the time delay between echoes of an ultrasound pulse emitted by an ultrasound inspection device into an object, the method comprising:
    i) with the ultrasound probe in engagement with a front-wall feature of the object such that the ultrasound inspection device's ultrasound axis is arranged at an angle relative to the nominal surface normal of the front-wall feature, taking an ultrasound measurement which comprises the ultrasound inspection device emitting an ultrasound pulse and recording echoes thereof; and
    ii) determining the time delay between echoes of the pulse via a time delay determination process which adjusts the time delay calculation based on the angle of the ultrasound inspection device's ultrasound axis with respect to the nominal surface normal of the front-wall feature
