Abstract
A method for diagnosis includes capturing a sequence of two-dimensional ultrasound images of a moving organ within a body of a patient. At least one contour of the organ is identified in a succession of the images in the sequence and is processed to generate an output indicative of motion of the organ over time.
Claims29
A method for diagnosis, comprising:
- capturing a sequence of two-dimensional ultrasound images of a moving organ within a body of a patient;
- identifying at least one contour of the organ in a succession of the images in the sequence;
- and
- processing the at least one identified contour to generate an output indicative of motion of the organ over time.
1 more element
A method for diagnosis, comprising:
- capturing multiple ultrasound input images of a moving organ within a body of a patient;
- collecting data that are indicative of respective local values of a physiological parameter at locations on a surface of the moving organ;
- and
- generating a sequence of three-dimensional images, responsively to the input images and the collected data, showing movement of the organ while superimposing an indication of changes in the local values on the surface in the three-dimensional images as the organ moves in the three-dimensional images in the sequence.

Diagnostic apparatus, comprising:
- an acoustic transducer, which is configured to capture a sequence of two-dimensional ultrasound images of a moving organ within a body of a patient;
- and
- an image processor, which is configured to identify at least one contour of the organ in a succession of the images in the sequence, and to process the at least one identified contour to generate an output indicative of motion of the organ over time.
Diagnostic apparatus, comprising:
- an acoustic transducer, which is configured to capture multiple ultrasound input images of a moving organ within a body of a patient;
- an invasive probe, which is configured to collect data that are indicative of respective local values of a physiological parameter at locations on a surface of the moving organ;
- and
- an image processor which is configured to generate, responsively to the input images and the collected data, a sequence of three-dimensional images showing movement of the organ while superimposing an indication of changes in the local values on the surface in the three-dimensional images as the organ moves in the three-dimensional images in the sequence.
