摘要： A method and apparatus are described for harmonic imaging using a transducer operated in the k31 mode. In one embodiment, the invention includes a transducer operative in a k31 mode, a transmitter for transmitting first signals to the transducer assembly, and a receiver for processing second signals received by the transducer assembly at a harmonic of the frequency of the first signals. In another embodiment, a method of operating an ultrasound system includes emitting first signals in a first frequency range from a transducer operating in the k31 mode, projecting the signals into a body, and detecting second signals confined to a second frequency range.

摘要： This invention describes automatically tracing a tissue border in an ultrasonic image which is accomplished by acquiring one or more images, locating anatomical landmarks in the image, fitting a border trace to the anatomical landmarks, and displaying an ultrasonic image in which a tissue border has been automatically traced. Adjustable control points are located on the displayed border, enabling the automatically drawn border to be manually adjusted by a rubberbanding technique.

摘要： Ultrasonic cardiac image information is acquired and segmented by automatic border detection. The segmented ultrasonic information is used to display regional wall motion over time. The segmented information may be presented in a color-coded representation, or entered automatically as qualitative or quantitative measures on a scorecard of cardiac performance. The inventive technique is applicable to both two dimensional and three dimensional ultrasonic image information.

摘要： An ultrasonic transducer assembly (10) for diagnostic imaging is provided. The ultrasonic transducer includes an elongated housing (12) that is configured and dimensioned to accommodate applicable anatomical constraints. The assembly includes a sensor assembly (20) that includes a two-dimensional matrix array of transducer elements (22) and a translation mechanism (32) to physically translate the two-dimensional matrix array of transducer elements (22) through a field of view of approximately 140 degrees by 80 degrees. An articulation control mechanism (38) allows a clinician to move the tip (14) of the ultrasonic transducer (10) into a desired imaging position, e.g., for fetal imaging.

摘要： A diagnostic ultrasound imaging system displays a gallery of ultrasound images each of which was obtained using a different setting for the imaging system. One of the images in the gallery is selected, and the imaging system is then set up to use the setting that was used to obtain the selected ultrasound image. The images displayed in the gallery may be obtained using different settings or different combinations of settings, and settings may be selected by selecting one or more images from each of several sequentially displayed galleries.

摘要： A diagnostic ultrasound imaging system includes a display monitor having a viewing screen with an aspect ratio substantially wider than 4:3. The wide aspect ratio screen is able to display horizontally elongated images typically obtained in ultrasound imaging using a greater percentage of the viewing screen compared to display monitors used in prior art ultrasound imaging systems. As a result, the images can be seen with greater size and resolution without cutting off portions of the images. The display monitor is preferably rotatable 90 degrees to provide a viewing screen having an aspect ratio substantially narrower than display monitors used in prior art ultrasound imaging systems, thereby providing a viewing screen that is better able to show deep images.

摘要： A digital scanline signal processor which processes beamformed echo signals includes a normalization circuit, a speckle reduction processor, and a gain stage which amplifies detected echo signals. The normalization circuit applies depth dependent gain to the scanline signals to equalize the amplitudes in channels of the processor with different passband characteristics. A log compression circuit includes two compression functions for low level and high level echo signals.

摘要： An ultrasonic diagnostic imaging system is provided which is capable of sending and receiving electronic messages directly from the user interface of the ultrasound system. This capability permits physicians to send messages, reminders, and diagnostic examination instructions directly to ultrasonographers using the system. The system operator is also able to call a physician to an ultrasound exam by means of an electronic message. Electronic messages can also be used to send and receive diagnostic reports and images, to retrieve diagnostic information such as the system presets for a particular type of ultrasonic examination, and to send and receive information from a hospital information system.

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.
