Abstract
To improve the data quality in detecting cardiac wall motion, regions of abnormal wall motion are detected from a view. The scan settings are then changed to focus scanning on each region, providing improved data such as data with more speckle being present. The scan settings may include changing an orientation of the scan plane, reducing out-of-plane motion, and/or increasing speckle content. The improved data is used to more accurately determine strain.
Claims20
A method for detecting cardiac wall motion with a medical ultrasound scanner, the method comprising:
- first scanning, by the medical ultrasound scanner using first values of scan settings, a first plane through a heart of a patient, the first plane scanned at different times providing first ultrasound data representing the heart at the different times;
- detecting abnormal wall motion from the first ultrasound data;
- second scanning, by the medical ultrasound scanner using second values of the scan settings, a region of the abnormal wall motion in a second plane, the second settings different than the first values of the scan settings, the second plane different than the first plane, the second scanning resulting in second ultrasound data;
- determining strain for the abnormal wall motion from the second ultrasound data;
- and
- displaying an image representing the strain.
An ultrasound system for detecting cardiac wall motion, the system comprising:
- an ultrasound scanner configured to detect a location of abnormality of the cardiac wall motion for a patient, scan the location with different values of one or more settings, and determine strain of the cardiac wall motion at the locations from ultrasound data from the scan using at least one of the different values of the one or more settings;
- and
- a display configured to display an image of the strain.
A non-transitory computer readable storage medium having stored therein data representing instructions executable by a programmed processor for detecting cardiac wall motion, the storage medium comprising instructions for:
- scanning a heart of a patient in a standardized view;
- detecting abnormal wall motion of the heart from the standardized view;
- acquiring B-mode data in a patch at the abnormal wall motion;
- determining strain from the B-mode data for the patch;
- and
- displaying a strain map including a first segment of the strain map having the strain determined from the B-mode data for the patch and a second segment of the train map having another strain determined from the standardized view.
