摘要： An accurate real-time measurement of a displacement vector is achieved on the basis of the proper beamforming that require a short time for obtaining one echo data frame without suffering affections by a tissue motion. The displacement measurement method includes the steps of: (a) yielding ultrasound echo data frames by scanning an object laterally or elevationally using an ultrasound beam steered electrically and/or mechanically with a single steering angle over an arbitrary three-dimensional orthogonal coordinate system involving existence of three axes of a depth direction, a lateral direction, and an elevational direction; and (b) calculating a displacement vector distribution by implementing a block matching on the predetermined ultrasound echo data frames yielded at more than two phases.

摘要： A displacement measurement method for achieving, at each position of interest, high accuracy measurement of a displacement, a velocity and a strain in an actually generated beam direction by measuring the beam direction angle from ultrasound echo data. The method includes the steps of: generating an ultrasound echo data frame through scanning an object in a lateral direction with an ultrasound steered beam having one steering angle; calculating both a beam direction and a frequency in the beam direction based on an azimuth angle φ=tan−1(fy/fx), a polar angle θ=cos−1[fz/(fx2+fy2+fz2)1/2], and a frequency (fx2+fy2+fz2)1/2 in the case where first spectral moments calculated from local ultrasound echo data at plural different temporal phases are expressed by a three-dimensional frequency vector (fx, fy, fz); and calculating a displacement component in the beam direction at each position of interest generated between plural different temporal phases.
