Title:
マルチパラメトリック組織の剛性の定量化
Document Type and Number:
Japanese Patent JP7237079
Kind Code:
B2
Abstract:
The present disclosure describes ultrasound systems and methods configured to determine stiffness levels of anisotropic tissue. Systems can include an ultrasound transducer configured to acquire echoes responsive to ultrasound pulses transmitted toward anisotropic tissue having an angular orientation with respect to a nominal axial direction of the transducer. Systems can also include a beamformer configured to control the transducer to transmit a push pulse along a steering angle for generating a shear wave in the anisotropic tissue. The steering angle can be based on the angular orientation of the tissue. The transducer can also be controlled to transmit tracking pulses. Systems can also include a processor configured to store tracking line echo data generated from echo signals received at the transducer. In response to the echo data, the processor can detect motion within the tissue caused by propagation of the shear wave and measure the velocity of the shear wave.
