ABSTRACT:
The ultrasonic apparatus contains an imaging lens for focusing ultrasound waves, a diverging device for receiving converging ultrasound waves from the lens and for transmitting ultrasound waves such that beams coming from a single object point are focused along a focal line, and an ultrasound detector positioned at the focal line indicating the ultrasound waves. The detector contains a large number of elongated detector elements. In particular, the diverging device comprises an acoustic mirror containing a reflecting surface which has a diverging effect on impinging beams of ultrasound waves. Preferably, the mirror may have a reflecting surface which is formed by a large number of parallel parabolic lines.
