Various tissue displacement vector measurement methods have been proposed by us, i.e., the multidimensional cross-spectrum phase gradient method (MCSPGM), the multidimensional autocorrelation method (MAM) and the multidimensional Doppler method (MDM). In this paper, actual measurement results obtained by MAM and MDM are reported. Specifically, for a compressed agar-graphite phantom (infinitesimally compressed, ≈0.07%; largely compressed, ≈0.7%), the measurement results for axial strain using MAM and MDM are shown and compared with those using MCSPGM, the conventional one-dimensional (1D) AM and the direct strain measurement method based on 1D AM (DSMM). Although DSMM was also developed by us in 1993, the method and the actual measurement results have not been reported elsewhere. Because the multidimensional methods can provide more accurate axial displacement measurements in real time and enable displacement vector measurement, 1D AM and DSMM might now be ineffective for practical applications.
