摘要： A method and an apparatus for automatically initializing and adjusting the Doppler sample gate position and size settings based on actual vessel image data. A vessel segment search method employs an object search technique based solely on geometric and morphological information in a binarized vessel image obtained from either B-mode or color flow image data. The morphologically best or nearest vessel segment within a target search region in the two-dimensional image is found. The sample gate is placed at or near the center of the targeted vessel segment. The sample gate size is adjusted in relation to the vessel size. Then the best available steering angle that minimizes the Doppler angle is selected.

摘要： An ultrasound transmitter generates ultrasound signals at an adjustable pulse repetition rate. A Doppler unit generates Doppler signals from ultrasound backscattered signals and stores them in a memory. A logic unit performs an algorithm which automatically adjusts the polarity and position of the velocity scale of a display and automatically adjusts the pule repetition rate of the transmitter based on analysis of the signals.

摘要： Method and apparatus for automatically maintaining the range gate inside a moving blood vessel during ultrasound imaging. The range gate can be maintained at the vessel center, or at a certain distance from one of the vessel boundaries, or at a certain ratio of the respective distances from the two boundaries. The user first places the range gate on the blood flow being examined. An algorithm processes each successive image frame and automatically updates the information about vessel boundary positions and the vessel orientation angle in the vicinity of the range gate. If the range gate position relative to the vessel boundaries is different than that in the previous frame by more than a predetermined amount, the position of the range gate graphic and the orientation of the vessel slope cursor (and the Doppler angle) are automatically adjusted to the new values.

摘要： A Doppler unit generates a Doppler signal from ultrasound backscattered signals. A logic unit performs a Fourier transform and compresses the resulting signals according to a compression curve determined in part by the noise level in the system. The peak values of the compressed signals also may be used to adjust the video gray mapping of the compressed signals in order to improve the appearance of a Doppler image on a display.

摘要： A method for automatic Doppler angle estimation based on the B-mode and color flow (if available) image. The method uses an algorithm for automatic vessel slope measurement which first finds an optimal initial point within the sample volume or range gate, and then searches for the most reliable pixel points (near or far walls) based on a combination of intensity-only and intensity-difference thresholds, before performing a slope estimation. B-mode intensity data and, optionally, color flow velocity or power data (before gray/color mapping) are used. The algorithm may also be applied to methods for automatic tracking of vessel diameter and flow rate calculations, although the primary objective is to achieve automatic Doppler angle estimation in an ultrasound scanner.

摘要： A method and an apparatus for automatically maintaining the Doppler sample gate position at a preselected vessel position in B-mode or color flow images during tissue or probe motion. The sample gate is locked onto the selected vessel automatically when the vessel position has changed. Optionally, the vessel slope cursor is automatically updated when the vessel position has changed. The method employs pattern matching of images from successive frames to determine how much a vessel in the image frame has been translated and rotated from one frame to the next. Preferably, either a cross-correlation method is applied to the imaging data in the spatial domain to determine the relative object translation and/or rotation between image frames, or a matched filtering method is applied to the imaging data in the frequency (i.e., Fourier) domain to determine the relative object translation and/or rotation between image frames.

摘要： Method and apparatus for automatically detecting and sizing cystic objects in ultrasound imaging. The cystic objects can be automatically detected by the steps of reading an image frame from memory; defining a search region within the image frame or a decimated version of the image frame; binarizing the pixel values within the search region based on a pixel value threshold that is adaptive to local pixel value statistics; morphological filtering the binarized pixel values to eliminate structures smaller than the speckle size; counting the number of continuous objects and keeping track of their area; and rejecting objects that are outside a predetermined size range. Each detected cystic object is automatically sized and graphical information representing the results of the automatic sizing process may be displayed.
