Abstract

A method for producing a region of interest on an image of a medical signal waveform acquired from a patient displayed on a computer screen includes the steps of receiving interaction to move through the image of the medical signal waveform; displaying guidelines on the image to define a region of interest; acting upon data in the region of interest; and displaying the image, the acted upon data, and the defined region of interest on the computer screen.

Claims

1. A method for producing a region of interest on an image of a medical signal waveform acquired from a patient displayed on a computer screen, comprising the steps of:

receiving instructions to move through the image of the medical signal waveform;

displaying guidelines on the image to define a region of interest;

acting upon data in the region of interest; and

displaying the image with the acted upon data, and the defined region of interest on the computer screen.

2. The method of claim 1, including the step of changing the image being acted upon.

3. The method of claim 1, including the step of reconfiguring the guidelines.

4. The method of claim 1, including the step of storing the displayed image.

5. The method of claim 1, including the step of annotating the displayed image in the defined region.

6. The method of claim 1, wherein the displayed image of the medical signal waveform is one selected from a group consisting of ventricular, atrial, and arterial waveforms.

7. The method of claim 6, wherein the medical signal waveform is from an anatomical structure.

8. The method of claim 7, wherein the anatomical structure is a human heart.

9. The method of claim 8, wherein the mechanism is a hemodynamic monitoring system.

10. The method of claim 1, wherein the step of receiving instructions includes inputs from an input device selected from a group consisting of a mouse, a joystick, a keyboard, a track ball, a touch screen, a voice recognition control and a light wand

11. A tool to produce a region of interest on an image of a medical signal waveform acquired from a patient displayed on a computer screen, the tool comprising:

a mechanism configured to obtain the image of the pressure waveform;

means for receiving instructions to move through the image;

means for displaying guidelines on the image defining a region of interest;

means for calculating data in the region of interest; and

displaying the image, the calculated data, and the defined region of interest on the computer screen.

12. The tool of claim 11, including a means for changing the image being acted upon.

13. The tool of claim 11, including a means for reconfiguring the guidelines.

14. The tool of claim 11, including a means for storing the displayed image.

15. The tool of claim 11, including a means for annotating the displayed image in the defined region.

16. The tool of claim 11, wherein the displayed image in one selected from a group consisting of ventricular, atrial and arterial waveforms.

17. The tool of claim 16, wherein the medical signal waveform is from an anatomical structure.

18. The tool of claim 17, wherein the anatomical structure is a human heart.

19. The tool of claim 18, wherein the mechanism is a hemodynamic monitoring system.

20. The tool of claim 11, wherein the means for receiving instructions includes an input signal from an input device selected from a group consisting of a mouse, a joystick, a keyboard, a track ball, a touch screen, a voice recognition control and a light wand.
