    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 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: An imaging system includes a diagnostic ultrasound front end module, the front end module including a transducer, a robotic armature (2), and a controller (4) electrically coupled to each of the front end module and the robotic armature. The controller is configured to employ the robotic armature to move the transducer relative to an anatomical structure, including wherein the controller is operable in a feedback control mode to detect key attributes in an acquired image or data set received from the front end module, calculate a desired adjustment to the position of the transducer based on the key attributes detection, and employ the robotic armature to apply the desired position adjustment.
