METHOD OF SCANNING ULTRASONIC DIAGNOSING DEVICE |
摘要 |
An ultrasonic imaging system includes a linear array of transducers of which a group of successively arranged transducers is selected and successively shifted to the next by at least one transducer. The transducers of the selected group are successively activated at respective delay times to transmit a radial scan beam which appears to emanate from a hypothetical point source located behind the transducer array. A scan converter is provided for conversion of analog echo signals in sector scan format to digital echo data in raster format for visual display. |
