Abstract

The invention is directed to systems and methods for detecting and presenting textural information from medical images. In one example embodiment, a medical imaging system includes an imaging transducer assembly configured to emit one or more energy pulses and receive one or more echo signals, and a console, coupled to the imaging transducer assembly, configured to receive the one or more echo signals, detect one or more signals that correspond with an abnormality, and invoke an alert in response to the detection of the one or more signals that correspond with an abnormality.

Claims

1. A medical imaging system comprising:

an imaging transducer assembly configured to emit one or more energy pulses and receive one or more echo signals; and

a computer console coupled to the imaging transducer assembly and configured to receive the one or more echo signals, detect one or more signals that correspond with an abnormality, and invoke an alert in response to the detection of the one or more signals that correspond with an abnormality.

2. The medical imaging system of claim 1, wherein the abnormality is vulnerable plaque.

3. The medical imaging system of claim 1, wherein the alert is at least one of an audio alert and a visual alert.

4. The medical imaging system of claim 1, wherein the console is configured to detect a plurality of abnormalities, and assign a unique alert to each of the plurality of abnormalities.

5. The medical imaging system of claim 1, wherein the console is configured to detect a plurality of abnormalities, and assign a unique alert to at least two of the plurality of abnormalities.

6. The medical imaging system of claim 1, wherein the imaging transducer assembly has an axis and is configured to rotate on its axis, and wherein the imaging transducer assembly emits energy pulses and receives one or more echo signals while rotating on its axis.

7. The medical imaging system of claim 1, wherein the imaging transducer assembly is an ultrasound transducer assembly.

8. The medical imaging system of claim 1, wherein the imaging transducer assembly is an optical coherence tomography device.

9. The medical imaging system of claim 1, wherein the computer console includes a processor, a display screen, and graphics hardware.

10. The medical imaging system of claim 1, further comprising an automatic pullback system coupled to the imaging transducer assembly.

11. The medical imaging system of claim 1, wherein the computer console is configured to generate a plurality of frames of medical images, and configured to enable a user to bookmark a frame in which an abnormality is detected.

12. A method for imaging a vascular system comprising the steps of:

inserting an imaging catheter into the vascular system;

generating one or more image signals via the imaging catheter;

analyzing the one or more image signals in real-time for an abnormality; and

invoking an alert once an abnormality is detected.

13. The method of claim 12, wherein the abnormality is vulnerable plaque.

14. The method of claim 12, wherein the alert is at least one of an audio alert and a visual alert.

15. The method of claim 12, further comprising analyzing the one or more image signals in real-time for a plurality of abnormalities, and assigning a plurality of unique alerts, each corresponding with one of the plurality of abnormalities.

16. The method of claim 12, wherein the image signals are generated as the imaging catheter is automatically pulled back.

17. The method of claim 12, further comprising generating a plurality of frames of medical images and enabling a user to bookmark a frame in which an abnormality is detected.

18. A medical imaging system comprising:

an imaging transducer assembly configured to emit one or more energy pulses and receive one or more echo signals; and

a computer console coupled to the imaging transducer assembly having a processor and a computer readable medium with a set of instructions to be executed by the processor, said instructions including;

receiving the one or more echo signals,

detecting one or more signals that correspond with an abnormality,

assigning a unique alert with the abnormality; and

and invoking the unique alert in response to the detection of the one or more signals that correspond with the abnormality.

19. The medical imaging system of claim 18, wherein the abnormality is vulnerable plaque.

20. The medical imaging system of claim 18, wherein the alert is at least one of an audio alert and a visual alert.

21. The medical imaging system of claim 18, wherein the set of instructions further includes detecting a plurality of abnormalities, and assigning a unique alert to each of the plurality of abnormalities.

22. The medical imaging system of claim 18, wherein the set of instructions further includes detecting a plurality of abnormalities, and assigning a unique alert to at least two of the plurality of abnormalities.

23. The medical imaging system of claim 18, wherein the imaging transducer assembly has an axis and is configured to rotate on its axis, and wherein the imaging transducer assembly emits energy pulses and receives one or more echo signals while rotating on its axis.

24. The medical imaging system of claim 18, wherein the imaging transducer assembly is an ultrasound transducer assembly.

25. The medical imaging system of claim 18, wherein the imaging transducer assembly is an optical coherence tomography device.

26. The medical imaging system of claim 18, wherein the computer console includes a processor, a display screen, and graphics hardware.

27. The medical imaging system of claim 18, further comprising an automatic pullback system coupled to the imaging transducer assembly.

28. The medical imaging system of claim 18, wherein the computer console is configured to generate a plurality of frames of medical images, and configured to enable a user to bookmark a frame in which an abnormality is detected.
