Combined B-mode / tissue doppler approach for improved cardiac motion estimation in echocardiographic images

摘要

A method for cardiac motion estimation includes: receiving a set of echocardiographic images of a heart, the echocardiographic images including B-mode ultrasonic images and Tissue Doppler Imaging (TDI) images; and calculating, by the image processing machine, a motion field representing the motion of the heart using the B-mode ultrasonic images and applying a velocity constraint from the TDI images. A system for cardiac motion estimation, includes: an imaging device configured to acquire a set of echocardiographic images of a heart, the echocardiographic images including B-mode ultrasonic images and TDI images; a data storage device in communication with the imaging device and configured to store the set of echocardiographic images; an image processing machine in communication with the data storage device and configured to calculate a motion field representing the motion of the heart using the B-mode ultrasonic images and applying a velocity constraint from the TDI images.

1. A method for cardiac motion estimation, comprising:
receiving, by an image processing machine, a set of echocardiographic images of a heart, the echocardiographic images including B-mode ultrasonic images and Tissue Doppler Imaging (TDI) images; transforming, by the image processing machine, the set of echocardiographic images of the heart into a motion field representing the motion of the heart by simultaneously combining motion components in a plurality of directions from speckle data from the B-mode ultrasonic images and information from the TDI images; and outputting, to an output device, the motion field representing motion of the heart.
