    摘要: 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.

    摘要: A technique for scanning an image field with adjacent beams of ultrasonic energy is provided in which initially transmitted beams are transmitted along beam directions down the center of the image field. Subsequent beams are alternately transmitted on either side of the initially transmitted beams and at increasing lateral locations in said field with respect to the locations of the initially transmitted beams until the full image field has been scanned. In one alternative embodiment initially transmitted beams are transmitted along beam directions at the lateral sides of the image field. Subsequent beams are alternately transmitted on either side of the initially transmitted beams and at lateral locations which converge toward the center of the image field until the full image field has been scanned. In another alternative embodiment initially transmitted beams are transmitted on one side of the center of the image field, subsequent beams diverge from the locations of the initially transmitted beams, and concluding beams laterally converge at a location on the other side of the center of the image field.

    摘要: An ultrasonic apparatus for scanning an image field of a subject extending in substantially opposite directions from the middle of said field to lateral extremes of said field with beams of ultrasound which are transmitted and received in a pattern in which the beams are spatially adjacent to each other over said image field. This apparatus has means for minimizing multipath artifacts, comprising means for sequentially transmitting and receiving ultrasonic beams in successive beam directions along which the consecutively transmitted and receive beams are substantially spatially separated, and in an alternate manner. This means may include means for sequentially transmitting and receiving beams in successive beam directions that are divergent from a first beam direction located at a first location in said image field alternately each side of the first beam direction; and/or means for sequentially transmitting and receiving beams in successive beam directions that are convergent from two opposite beam directions alternately towards the center of said image field.

    摘要: An ultrasonic diagnostic system is provided which automatically sets up the TGC characteristic to be used for a given ultrasound examination. Upon user selection of a particular ultrasound application, a setup controller accesses a predetermined TGC characteristic for the selected application. The predetermined TGC characteristic is used to control the gain of a TGC amplifier and is also displayed to the user. By adjustment of a series of TGC controls the user can vary the TGC characteristic from the predetermined characteristic.
