IMPROVED FREQUENCY COMPOSITE METHOD IN ULTRASONIC WAVE SHADOW AND ITS DEVICE |
摘要 |
A frequency program synthesizing apparatus and method is disclosed for controlling delay circuitry in ultrasonic imaging systems. The ultrasonic system includes a multi-element ultrasonic transducer for propagating ultrasonic energy into a subject, display apparatus for producing visual information about the subject from the ultrasonic energy, and imaging electronics for processing image information representing electrical signals from the transducer and employs the processed signals to cause the display to generate a visual image of internal subject structure. |
