Abstract
A method and system for slice alignment in multiple image views are provided. The method includes determining an adjustment of one of a plurality of image views to align an imaged object with at least one alignment marker. The method further includes updating the plurality of image views based on the adjustment. The updating includes at least one of rotating and translating the image views with respect to an intersection of the at least one alignment marker with another alignment marker.
Claims20
A method for slice alignment in a volumetric data set, the method comprising:
- determining an adjustment of one of a plurality of image views to align an imaged object with at least one alignment marker, the adjustment including at least one of (i) rotating the one image view with respect to an intersection of the at least one alignment marker with another alignment marker and (ii) translating the one image view;
- and
- updating the plurality of image views based on the adjustment.
A method for slice alignment in a volumetric data set of an imaged heart, the method comprising:
- displaying a plurality of apical views of the heart in combination with a plurality of alignment markers;
- displaying a plurality of short axis views of the heart, at least some of the plurality of short axis views displayed in combination with alignment markers;
- and
- updating the plurality of apical views and short axis views based on a user identified center point in at least two of the short axis apical views.
A method for slice alignment in a volumetric data set of an imaged heart, the method comprising:
- displaying a plurality of apical views of the heart in combination with a plurality of alignment markers;
- and
- updating the plurality of apical views based on user identified landmarks.
An ultrasound system comprising:
- an ultrasound probe for acquiring a volumetric ultrasound data set of a heart;
- and
- a processor having a slice alignment module configured to automatically align a plurality of views of the volumetric data set based on at least one of (i) a centerline alignment marker and a perpendicular intersection marker rotated about the intersection of the centerline marker and the perpendicular intersection marker in one of a 4-chamber apical view of the heart, a 2-chamber apical view of the heart and a long axis apical view of the heart, (ii) an identified center point in at least two short axis views of the heart, (iii) an identified left ventricular outlet tract in a short axis view of the heart, and (iv) a plurality of identified landmarks corresponding to a mitral annulus and an apex of a left ventricle of the heart.
