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.

An ultrasonic apparatus, comprising:
- (a) focusing means for focusing ultrasound waves;
- (b) an diverging acoustic mirror positioned behind said focusing means and containing a reflecting surface;
- and
- (c) an ultrasound detector containing a plurality of elongated detector elements;
- wherein said reflecting surface of said diverging acoustic mirror reflects converging ultrasound waves from said focusing means such that the beams arriving so as to focus on a single point are diverged such as to focus along a focal line and wherein said ultrasound detector is positioned at said focal line for receiving said diverged ultrasound waves from said diverging acoustic mirror.
