摘要:
A method is described for acquiring 3D quantitative ultrasound elastography volumes. In one embodiment, the method comprises using a 2D ultrasound transducer to scan a volume of tissue through which shear waves are created using an external vibration source, the synchronized measurement of tissue motion within the plane of the ultrasound transducer with the measurement of the transducer location in space, the reconstruction of tissue displacements in time and space over a volume from this synchronized measurement, and the computation of one or several mechanical properties of tissue from this volumetric measurement of displacements. The tissue motion in the plane of the transducer may be measured at a high effective frame rate in the axial direction of the transducer, or in the axial and lateral directions of the transducer. The tissue displacements over the measured volume may be interpolated over a regular grid in order to make the computation of mechanical properties easier.
