Scanning techniques in grey-scale ultrasonography.

摘要: In the past two years technological basis of ultrasonic diagnosis has developed rapidly in direction grey-scale imaging. Hitherto imaging been directed primarily at twodimensional display relatively large echoes that are returned by major organ interfaces: new development aims displaying, addition, weak arise from fine structure tissues themselves. Such a technique results visualization consistency rather than its mere outline. This permits differential diffuse pathologies which recognized specific pattern produced each pathological process. Thus, liver for example, appearances fatty infiltration, cirrhosis, lymphocytic malignant chronic inflammatory changes and viral hepatitis may be separately differentiated. There is an important practical implication this approach, arises process ec...
