Abstract
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.
Claims21
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.
In a non-transitory computer readable storage medium having stored therein data representing instructions executable by a programmed processor for motion artifact suppression for three-dimensional parametric ultrasound imaging, the storage medium comprising instructions for:
- motion tracking for blocks of ultrasound data acquired with multiple beam reception in a volume scan, timing of the volume scan being different for blocks spaced in one direction than for blocks spaced in another direction;
- correcting for the timing being different for the directions;
- and
- displaying an image, the image being a function of the ultrasound data after the correcting.
A method for motion artifact suppression for three-dimensional parametric ultrasound imaging, the method comprising:
- detecting a direction of movement of anatomy within a patient;
- ultrasonically scanning, with a transducer, a volume with ultrasound in a pattern sweeping across rows of the volume in sequence;
- and
- aligning the pattern with the anatomy as a function of the direction of the movement of the anatomy.
