Ultrasonic Diagnosis of Ischemic Cardiodisease
First Claim
1. A method for depicting the functioning of the heart from a sequence of images acquired during a phase of the heart cycle comprising:
- acquiring a sequence of images of the heart during a selected phase or phases of the heart cycle, which images include the mitral valve;
segmenting and distinctively distinguishing from the rest of each image the location of the mitral valve in the images of the sequence; and
displaying in a single heart image the progressive locations of successive positions of the mitral valve during a real time display of the sequence of images.

Abstract
A diagnostic imaging method and ultrasound system are described for detecting abnormalities of the left ventricle of the heart. A sequence of images including the mitral valve is acquired and processed to identify the location of the mitral valve in each of the images in the sequence. A graphic is displayed with the images depicting the location of the mitral valve in the current image and in each of the preceding images of the sequence. Preferably the mitral valve location is identified by automatic detection of the mitral valve plane in each of the images. A desirable graphic color-codes each of the successively different mitral valve locations in the graphic. The image and graphic can be viewed in real time to discern the effects of conduction delay and infarction of the left ventricle.

15. An ultrasonic diagnostic imaging system for analyzing the performance of the heart comprising:
-
a probe having a plurality of transducer elements; an image processor coupled to the probe which acts to produce a sequence of B mode images; an automated border detection processor, which operates to identify the location of the mitral valve in a sequence of B mode images; a graphic display processor, responsive to the identification of the location of the mitral valve in a sequence of B mode images, which act to produce a graphic distinctively depicting the locations of the mitral valve from the rest of the image in a sequence of real time B mode images; and a display responsive to the graphic display processor which acts to display a sequence of B mode images with a graphic depicting the progressive locations of the mitral valve in previous images in the sequence. - View Dependent Claims (16, 17, 18)

19. An ultrasonic diagnostic imaging system for analyzing the performance of the heart comprising:
-
a probe having a plurality of transducer elements; an image processor coupled to the probe which acts to produce a sequence of B mode images; a user control by which a user can identify the location of the mitral valve in at least one of a sequence of B mode images; a graphic display processor, responsive to the identification of the location of the mitral valve in a sequence of B mode images, which act to produce a graphic distinctively depicting the locations of the mitral valve from the rest of the image in a sequence of B mode images; and a display responsive to the graphic display processor which acts to display a real time sequence of B mode images with a graphic depicting the progressive locations of the mitral valve in previous images of the sequence. - View Dependent Claims (20)
