Estimating distribution, fluctuation and/or movement of electrical activity through a heart tissue

1. A computer implemented method for processing measurement data from 12-lead electrocardiogram, ECG, electrodes on an outer surface of a subject including the computer:

obtaining a subject-specific three-dimensional, 3D, anatomical model of a heart and torso of the subject;

obtaining, using a 3D camera, a three-dimensional photograph of an outer surface of the torso of the subject including position information of the electrodes on the outer surface of the torso of the subject;

aligning the three dimensional photograph with the subject-specific three-dimensional model;

determining a position of each electrode of the 12-lead ECG electrodes in the subject-specific three-dimensional model from the three dimensional photograph;

automatically, using the 3D camera, determining an identification of each electrode;

comparing detected electrode positions of the electrodes in the three-dimensional model with predetermined 12-lead ECG electrode positions;

automatically determining a misplaced electrode relative to the predetermined 12-lead ECG electrode positions based on the comparison; and

recording an ECG of the misplaced electrode and, responsive to the determining of electrode misplacement and using a torso geometry from the three-dimensional model, reconstructing from the ECG recorded of the misplaced electrode, a reconstructed ECG for an associated non-misplaced, predetermined 12-lead electrode position.

2. The method of claim 1 , wherein the three-dimensional model of the torso of the subject is derived from a medical imaging system.

3. The method of claim 1 , wherein the aligning includes minimizing distances between the three-dimensional photograph and the three-dimensional model.

4. The method of claim 1 , further including determining the identification of each electrode from the three-dimensional photograph.

5. The method of claim 4 , wherein the identification is one of a color, a shape, number, or a code.

6. The method of claim 1 , further including determining whether electrodes are positioned in swapped positions.

7. The method of claim 6 , further including swapping back signals of swapped electrodes.

8. The method of claim 1 , including indicating whether the electrodes are positioned in a desired position.

9. The method of claim 8 , further including indicating a direction and/or distance for repositioning an electrode to the desired position.

10. The method of claim 1 , further including removing image data relating to a face of the subject from the three-dimensional photograph.

11. A system for processing measurement data from 12-lead electrocardiogram, ECG, electrodes on an outer surface of a subject, the system including:

a model input device configured to obtain a subject-specific three-dimensional, 3D, anatomical model of a torso of the subject;

a 3D photographic imaging device configured to obtain a three-dimensional photograph of an outer surface of the torso of the subject and arranged for determining an identification of each electrode;

a processor configured to:

align the three-dimensional photograph with the subject-specific three-dimensional model;

determine a position of each electrode of the 12-lead ECG electrodes in the subject specific three-dimensional model from the three-dimensional photograph;

compare detected electrode positions of the electrodes in the three-dimensional model with predetermined 12-lead electrode positions in the three-dimensional model;

automatically determine a misplaced electrode relative to the predetermined 12-lead ECG electrode positions based on the comparison; and

record an ECG of the misplaced electrode and, responsive to the determining of electrode misplacement and using a torso geometry from the three-dimensional model, reconstruct from the ECG recorded of the misplaced electrode, a reconstructed ECG for an associated non-misplaced, predetermined 12-lead electrode position.

12. The system of claim 11 further including display means for displaying electrode positions in relating to the three-dimensional photograph and/or three-dimensional model.

13. The method of claim 4 , further including determining the identification of each electrode by determining the electrode positioned closest to a predefined electrode location, and defining this electrode as coupled to the predefined electrode location.
