ABSTRACT:
An ultrasonic imaging system and method are disclosed which include a transducer (10) for pulse insonification (16) of an object (14) and for receiving echo signals from within the object. Echo signals are converted to electrical signals at the transducer (10) and the electrical signals are supplied to a signal processor (30) for processing the same. The signal processor (30) includes a detector (40) and integrator (42) for integrating the detector output.
Echo signals obtained from a range zone (Z) which is opposite the focal point (F) from the transducer (10) are integrated by integrator (42).
The amplitude of echo signals from range zone (Z) is strongly dependent upon attenuation at the focal point (F) whereby the integrator (42) output (60) also is 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) normal to the beam axis (20).
