Ultrasonic image processing method and examination system for displaying an ultrasonic color-coded image sequence of an object having moving parts |
摘要 |
The invention relates to an ultrasonic image processing method having steps of: acquiring ultrasonic signals related to an object having moving parts in a medium; constructing an ultrasonic grayscale 2-D image sequence representing a cross-section of a segment of the object with respect to a longitudinal axis (X) perpendicular to the grayscale image lines (Z); estimating the displacements and the displacement gradients of a boundary of the object and: normalizing the gray levels in a boundary zone and color-coding the points of the boundary zone of the an image sequence in function of the displacement gradient values, in order to provide color-coded information of the object moving parts displacement variations. The invention also relates to an ultrasonic examination imaging system for carrying out said method having a color display system.
