ABSTRACT OF THE DISCLOSURE An ultrasonic imaging system and method are disclosed which include a transducer (10) for pulse insonification (16) of an object (14). Reflecting means (29) containing scatterers is acoustically coupled to object (14) opposite transducer (10). Echo signals received from within reflecting means (29) are converted to electrical signals at the transducer (10), which electrical signals are supplied to a signal processor (30) for processing the same. Echo signals obtained from a range zone (Z) within reflecting means (29) are integrated by integrator (42). The amplitude of echo signals from the range zone (Z) is strongly dependent upon attenuation at the focal point (F) whereby the integrator (42) output (60) also is strongly dependent upon attenuation at the focal point (F). The integrator (42) output (60) is supplied to a display (48) for use in establishing one pixel thereof. A C-scan display is provided by scanning the focal point (F) in a focal plane (22) substantially normal to the beam axis (20).
