Abstract
An improved use of ultrasound in the medical and non destructive testing areas is made nowadays. The very first ultrasonic apparatuses were performing in the A-scan mode, that is to say that a pulsed ultrasonic wavetrain was launched and the position in time of the echoes, which were reflected by the obstacles, were observed. In such a way, the motion of a moving obstacle (like a cardiac valve) may be studied or the defects (like scratches in a metal piece) may be detected. These informations are truly interesting, but a growing interest has evolved among the uses towards the visualization of the obstacles. A number of acoustic imaging apparatuses have been built for this purpose and the actual studies are directed towards the following two directions: first the amelioration of the image quality and second the extension of the application field for these apparatuses.
