New ultrasound techniques for blood flow estimation have been investigated in-vivo. These are vector velocity estimators (Transverse Oscillation, Synthetic Transmit Aperture, Directional Beamforming and Plane Wave Excitation) and adaptive spectral estimators (Blood spectral Power Capon and Blood Amplitude and Phase Estimation). It was shown that the vector velocity estimators can provide reliable angle independent estimates and new insight to the complexity of blood flow, and that adaptive spectral estimators can produce useful spectrograms faster than the conventional spectral Doppler method.
已在体内研究了用于血流估计的新型超声技术。这些技术包括矢量速度估计器（横向振荡、合成发射孔径、定向波束形成和平板波激发）以及自适应谱估计器（血流谱功率卡彭估计和血流幅度与相位估计）。结果表明，矢量速度估计器能够提供可靠的与角度无关的估计，并为血流复杂性提供新的见解，而且自适应谱估计器能够比传统谱多普勒方法更快地生成有用的频谱图。
