Abstract
For boundary detection, such as heart wall detection for strain or another quantification, the boundary is detected using multiple types of imaging, such as B-mode and contrast. The confidence in the detected locations is used to form a more accurate boundary, such as replacing low confidence locations from B-mode imaging with higher confidence locations from the contrast imaging. Even where experts may struggle to identify boundaries, a more accurate boundary is created and used by the image processor or processing.
Claims10
A method for quantification of heart wall performance with a medical ultrasound system, the method comprising:
- detecting, by an image processor, heart wall locations for each B-mode image in a sequence of B-mode images of a patient;
- determining, by the image processor, first confidence measures for the heart wall locations from the sequence of the B-mode images;
- detecting, by the image processor, the heart wall locations for each contrast image in a sequence of contrast images of the patient;
- determining, by the image processor, second confidence measures in the heat wall locations from the sequence of the contrast images;
- generating, by the image processor, a heart wall boundary for each of different times from the heart wall locations from the sequence of B-mode images, the heart wall locations from the sequence of contrast images, the first confidence measures, and the second confidence measures;
- calculating, by the image processor, a strain from the heart wall boundary for multiple of the different times;
- and
- displaying the strain.
