Motion Artifact Suppression for Three-Dimensional Parametric Ultrasound Imaging

摘要

Motion artifacts are suppressed for three-dimensional parametric ultrasound imaging. Motion tracking is performed so that the parameter values derived over time are based on return from the same locations. Distortion due to the scan pattern is accounted for in the results of the motion tracking, such as by re-sampling the results to deal with discontinuity in time between data from adjacent sub-volumes and/or by aligning the scan pattern based on a direction of motion.

主权项

1. A method for motion artifact suppression for three-dimensional parametric ultrasound imaging, the method comprising:
scanning a volume of a patient with multi-beam reception where multi-beam groups progress in time along a first row in a first direction, then along a second row in the first direction, the first row adjacent to the second row along a second direction, the spatially adjacent multi-beam groups of the different rows being scanned at non-adjacent times; spatially registering the spatially adjacent multi-beam groups between the first and second rows; calculating parametric information from ultrasound data from the scanning; accounting for contraction or dilation in the calculating, the accounting being a function of the spatially registering; and generating a parametric image representing the volume, the parametric image being a function of the parametric information.
