Abstract
Systems and methods for automatic correction of view foreshortening in cardiac echo using view synthesis. A trained image segmentation method is used to infer a 2D pose from the input image. The pose is transferred to a new view representing a non-foreshortened view plane. A non-foreshortened image is then rendered.
Claims20
A method for automatic correction of view foreshortening in cardiac echo using view synthesis, the method comprising:
- acquiring, by a medical imaging device, an image representing a foreshortened view of a heart of a patient;
- inferring, by a processor, a pose of the heart in the acquired image using a trained image segmentation model and a heart model;
- and
- generating, by the processor, a non-foreshortened image of the heart of the patient by transferring the inferred pose of the heart to a new synthetic view representing a standard image acquisition plane.
A system for automatic correction of view foreshortening in cardiac echo using view synthesis, the system comprising:
- an ultrasound probe configured to acquire an image of a cardiac region of a patient;
- an imaging processor configured to generate a non-foreshortened image of the cardiac region of the patient using novel view synthesis, the acquired image, and a heart model;
- and
- a display configured to display the non-foreshortened image.
A non-transitory computer implemented storage medium that stores machine-readable instructions executable by at least one processor for correction of view foreshortening in cardiac echo using view synthesis, the machine-readable instructions comprising:
- acquiring a foreshortened image of a cardiac region of a patient using a first view;
- determining a pose of one or more features of a heart of the patient in the foreshortened image;
- transferring the pose of the one or more features to a new view of the cardiac region, the new view from a different angle than the first view;
- and
- generating a non-foreshortened image from the new view.
