Abstract
Jittering in medical diagnostic ultrasound imaging is reduced, such as in steered spatial compounding. A pattern of decorrelation is used to detect motion between component frames, register component frames, and/or reduce jitter in the motion correction. The ultrasound imaging adapts as a function of the pattern.
Claims20
A method for reducing jittering in medical diagnostic ultrasound imaging, the method comprising:
- determining a pattern of decorrelation through a sequence of frames of ultrasound data;
- and
- adapting ultrasound imaging as a function of the pattern.
In a computer readable storage medium having stored therein data representing instructions executable by a programmed processor for reducing jittering in medical diagnostic ultrasound imaging, the storage medium comprising instructions for:
- identifying a jitter in motion estimation for a sequence of frames of ultrasound data associated with different steering angles;
- reducing the jitter in the motion estimation;
- and
- compounding the frames of the sequence as a function of the motion estimation with reduced jitter.
In a computer readable storage medium having stored therein data representing instructions executable by a programmed processor for reducing jittering in medical diagnostic ultrasound imaging, the storage medium comprising instructions for:
- acquiring, with a substantially stationary transducer, first component frames of data for steered spatial compounding, the component frames of data corresponding to different steering angles;
- determining a first decorrelation pattern across the first component frames;
- acquiring second component frames of data corresponding to the different steering angles;
- determining a second decorrelation pattern across the second component frames;
- and
- detecting motion of the transducer for the second component frames as a function of the first and second decorrelation patterns.
