ABSTRACT:
An ultrasonic diagnostic imaging system is provided in which a portion of an ultrasonic image can be selected for enlarged display as a "zoom" image. When the image portion is displayed in its enlarged format, the bandwidth of a filter in the ultrasonic information path is extended to increase the information content of the image portion when displayed in its enlarged format. The bandwidth is continuously optimized to maximize information content in consideration of the characteristics of the display while preventing the generation of scintillation artifacts caused by attempts to display information of an excessive bandwidth.
