Abstract
A fan-shaped scanning flaw detecting apparatus which includes a probe provided with an ultrasonic wave transmitting-and-receiving array transducer arranged along a circular arc and an acoustic lens for converging and converting an ultrasonic beam transmitted/received by the array transducer into a substantially parallel beam. The apparatus also includes a scanning function section that sequentially switches the transmitting and receiving operation of a group of operative transducer elements of the array transducer so as to make the ultrasonic beam perform fan-shaped scanning. A picturizing processor section forms a sectional image of an object to be examined on the basis of an echo signal obtained from the object to be examined and a display section displays the sectional image. A position detecting section detects a position where the ultrasonic beam is incident to the object to be examined when the probe is moved along a surface of the object to be examined. Image information of a sectional image of the object to be examined under a running path of the probe is formed by the picturizing processor section on the basis of two types of information, a first type representing the posi…
