WHAT IS CLAIMED IS:

1. An ultrasonic diagnostic imaging system for analyzing the synchronization of heart motion comprising:
a probe operable to acquire Doppler echo signals from moving tissue;
a Doppler processor coupled to the probe and responsive to the Doppler echo signals which acts to produce a real time tissue Doppler image sequence; and
a graphical processor coupled to the probe which acts to produce in real time graphs of velocity versus time for a plurality of locations of interest in the tissue Doppler image sequence.

2. The ultrasonic diagnostic imaging system of Claim 1, further comprising a user control which is operable to select the locations of interest.

3. The ultrasonic diagnostic imaging system of Claim 1, further comprising a display screen coupled to the Doppler processor and the graphical processor for displaying a real time image sequence of both a tissue Doppler image and graphs of velocity versus time for a plurality of locations of interest in the tissue Doppler image sequence.

4. The ultrasonic diagnostic imaging system of Claim 3, further comprising LOI icons displayed with the tissue Doppler image to indicate correspondence between cardiac anatomy and the graphs .

5. The ultrasonic diagnostic imaging system of Claim 3, wherein the graphs are displayed as static graphs which are updated periodically.

6. The ultrasonic diagnostic imaging system of Claim 3, wherein the graphs are displayed as static graphs which are updated continuously.

7. The ultrasonic diagnostic imaging system of Claim 3, wherein the graphs are displayed as
scrolling graphs.

8. The ultrasonic diagnostic imaging system of Claim 1, further comprising:
a user control operable to indicate the
plurality of locations in a tissue Doppler image corresponding to real time graphs,
wherein there is display correspondence between the indicated locations and the graphs .

9. The ultrasonic diagnostic imaging system of Claim 8, wherein the display correspondence is color correspondence .

10. The ultrasonic diagnostic imaging system of Claim 8, wherein the user control is further operable to adjust the locations of the plurality of
locations .

11. The ultrasonic diagnostic imaging system of Claim 10, wherein the user control is operable to adjust the position of LOI icons over the tissue Doppler image.

12. The ultrasonic diagnostic imaging system of Claim 11, wherein the tissue Doppler image comprises a grayscale image.

13. The ultrasonic diagnostic imaging system of Claim 11, wherein the user control is operable to adjust the position of LOI icons over a frozen image of the tissue Doppler image sequence.

14. The ultrasonic diagnostic imaging system of Claim 1, further comprising a tracker, responsive to the sequence of real time images, which acts to track the locations of interest in real time.

15. The ultrasonic diagnostic imaging system of Claim 14, wherein the tracker comprises a speckle tracker.

16. The ultrasonic diagnostic imaging system of Claim 14, wherein the tracker includes a border detector.

17. The ultrasonic diagnostic imaging system of Claim 14, wherein the tracker tracks by frame to frame correlation.

18. The ultrasonic diagnostic imaging system of Claim 11, wherein the adjustment of the position of an LOI icon causes a highlighting of a graph
corresponding to the adjusted LOI icon.

19. An echocardiographic method for analyzing left ventricular function comprising:
acquiring ultrasound data from the heart;
displaying a real time image sequence of the left ventricle;
indicating locations of the left ventricle where motion is to be analyzed; and displaying real time graphs of motion of the indicated locations .

20. The method of Claim 19, wherein indicating locations further comprises manipulating graphic indicators with reference to at least one image of the left ventricle.
