摘要： A system for displaying accumulated ultrasound images of tissue structures. A set of N image frames is used to produce a peak image display. Multiple peak image displays are produced by discarding the oldest image frame in the set of N image frames and replacing the discarded image frame with another more recent image frame. The more recent image frame is added to the set of image frames to produce a new set of N image frames. The new set of N image frames is used to produce another peak display image. If there is an undesirable amount of distortion or blur in the peak display images due to tissue motion, then the number of image frames in the set of N image frames can be reduced.

摘要： A method and apparatus for adjusting the shape of a region of interest (ROI) in a frame of imaging data in response to an operator-actuated change in the depth of the ROI. The displayed image has a background region of data acquired using a first imaging mode and an ROI of data acquired using a second imaging mode. The ROI is surrounded by the background region and bounded by an ROI graphic. The adjustment in the shape of the ROI is accomplished by programming the imaging system with an algorithm that maintains the height and the bottom width of the ROI substantially constant. Only the top width of the ROI and the angles of the edge lines are automatically changed in response to the operator-actuated change in ROI depth.

摘要： A method and an apparatus for color mapping of flow power data in which the flow states containing information of most interest to the user are enhanced, while flow states not containing information of interest are suppressed. This is accomplished using a color mapping having three segments which are connected at upper and lower knee points, the latter being settable either automatically or via operator inputs. In the automatic mode, the host computer determines the positions of the knee points based on analysis of a single or a mean image frame of power Doppler data or based on system parameters (e.g., dynamic range) set by the operator. The host computer then constructs a color mapping having the determined knee points and loads that color mapping into the video processor.

摘要： A method and an apparatus for three-dimensional ultrasound imaging of a needle-like instrument, such as a biopsy needle, inserted in a human body. The instrument is visualized by transmitting ultrasound beams toward the instrument and then detecting the echo signals using a linear array of transducer elements. The problem of ultrasound being reflected from a biopsy needle in a direction away from the transducer array is solved by steering the transmitted ultrasound beams to increase the angle at which the beams impinge upon the biopsy needle. Ideally the ultrasound beams are perpendicular to the biopsy needle. This increases the system's sensitivity to the needle because the reflections from the needle are directed closer to the transducer array. This can be accomplished using either the B mode or the color flow mode of an ultrasound imaging system. The acquired data for multiple two-dimensional image frames is gathered in memory to form a data volume, which is then processed to form a three-dimensional image (by projection) or a two-dimensional slice taken at an angle through the data volume. In particular, a two-dimensional slice which is coplanar with the inserted biopsy needle can be imaged.

摘要： An ultrasound system comprises a position sensing module, an imaging tracking module, a display and a user interface. The position sensing module detects spatial information associated with a volume of data. The display displays first and second images based on the volume of data. The first and second images comprise first and second portions of the volume of data, and the first and second portions are at least partially different with respect to each other. The user interface selects a first image tracking point on the first image. The first image tracking point is indicated on the first image with a first indicator. The image tracking module tracks the first image tracking point within the volume of data. The image tracking module indicates on the display a spatial relationship of the first image tracking point to the second image.
