摘要 |
An ultrasonic probe for performing a scanning of an ultrasonic wave by a reflection mirror is disclosed. The probe comprises an ultrasonic wave generating means formed by a focusing element, an ultrasonic transducer, and an ultrasonic focusing element added to the ultrasonic transducer, a reflecting mirror being a convex ultrasonic mirror for reflecting the ultrasonic wave from the ultrasonic wave generating means or a concave ultrasonic mirror for reflecting the ultrasonic wave from the ultrasonic wave generating means, the distance between the convex ultrasonic mirror and the focusing element and ultrasonic transducer is made shorter than a focal length of the ultrasonic transducer, the distance between the convex ultrasonic mirror and the ultrasonic focusing element added to the ultrasonic transducer is made shorter than a focal length of the ultrasonic focusing element, the distance between the concave ultrasonic mirror and the focusing element and ultrasonic transducer is made longer than a focal length of the ultrasonic transducer, and the distance between the concave ultrasonic mirror and the ultrasonic focusing element added to the ultrasonic transducer is made longer than a focal length of the ultrasonic focusing element.
