Clinical Ultrasound Pattern Recognition

Ultrasonic imaging diagnosis has become more sophisticated as instrument performance has advanced and as the educational base of its practitioners has extended. By and large, the method is used qualitatively to answer specific medical questions, usually those involving anatomic features delineated by fluid spaces or involving local changes in tissue macrostructure. Some physiologic information is inferred from the anatomic appearance, from target dynamics, and from ancillary forms of data manipulation and display, such as the Doppler frequency shift.
