ABSTRACT:
The insonification apparatus is designed for the examination of an object, preferably for medical examinations. The apparatus contains an ultrasonic wave-generating transducer for emitting ultrasonic waves toward an examination plane, and an imaging device having principal planes for passing ultrasound waves received from the examination plane toward an imaging plane. The acoustic image formed in the imaging plane is received by a receiving transducer and transferred into electrical signals. The apparatus also contains an ultrasound condensing device such as a lens, a mirror, or a combination of such elements. This condensing device forms an ultrasonic image of the wave-generating transducer in the aperture of the imaging device. Thus, an increased uniformity of the intensity distribution in the image plane and an increased image contrast for high-spatial frequency information are obtained.
