Abstract
An ultrasonic scanning device includes an ultrasonic sensor mounted for rotation. The sensor can be automatically oriented in a predetermined reference position from a random position. During a scanning operation the sensor is rotated by incremental angles. The length of the angles is changed after a predetermined time elapse following the initiation of a scanning operation.
