Abstract

A system includes a display and a processor. The processor is configured to: (i) receive a dataset including multiple data points, each data point corresponding to one or more properties of an organ of a patient, (ii) produce, based on a clustering criterion, at least a cluster including two or more of the data points, and (iii) produce and present on the display, a map of the organ and at least an object indicative of the cluster. In response to selection of the object by a user, the processor is configured to produce and present on the display, a two-dimensional (2D) table including the one or more properties of each of the clustered data points.

First claim

The invention claimed is:

1. A system, comprising:
a display; and
a processor, which is configured to: (i) receive a dataset comprising multiple data points, each data point corresponding to one or more properties of an organ of a patient, (ii) produce, based on a clustering criterion, at least a cluster comprising two or more of the data points, and (iii) produce and present on the display, a map of the organ and at least an object indicative of the cluster, and
in response to selection of the object by a user, produce and present on the display, a two-dimensional (2D) table comprising the one or more properties of each of the clustered data points.

2. The system according to claim 1 , wherein the organ comprises a patient heart, and wherein the clustering criterion selected from a list of criteria consisting of: (i) a location of the data point in the heart, (ii) a morphology of a signal acquired at the data point, (iii) a local activation time (LAT) measured at the data point, and (iv) an anatomical feature at the data point.

3. The system according to claim 1 , wherein the processor is configured to present at least the object by displaying the object over the map.

4. The system according to claim 1 , wherein the processor is configured to produce and present at least the object by displaying the object in an additional 2D table.

5. The system according to claim 1 , wherein the processor is configured to assign to the cluster a representative data value, which represents a calculated value corresponding to the clustered data points.

6. A method, comprising:
receiving a dataset comprising multiple data points, each data point corresponding to one or more properties of an organ of a patient;
producing, based on a clustering criterion, at least a cluster comprising two or more of the data points;
producing and presenting a map of the organ and at least an object indicative of the cluster; and
in response to selection of the object by a user, producing and displaying a two-dimensional (2D) table comprising the one or more properties of each of the clustered data points.

7. The method according to claim 6 , wherein the organ comprises a patient heart, and wherein the clustering criterion selected from a list of criteria consisting of: (i) a location of the data point in the heart, (ii) a morphology of a signal acquired at the data point, (iii) a local activation time (LAT) measured at the data point, and (iv) an anatomical feature at the data point.

8. The method according to claim 6 , wherein presenting at least the object comprises displaying the object over the map.

9. The method according to claim 6 , wherein presenting at least the object comprises displaying the object in an additional 2D table.

10. The method according to claim 6 , and comprising assigning, to the cluster a representative data value, which represents a calculated value corresponding to the clustered data points.

11. A method for multi-layered visualization, the method comprising:
receiving a dataset comprising multiple data points, each data point corresponding to one or more properties of an organ of a patient;
producing a first visualization layer by clustering, based on a clustering criterion, at least a cluster comprising two or more of the data points, and displaying, an object indicative of the cluster; and
producing a second visualization layer comprising a two-dimensional (2D) table having the one or more properties of each of the clustered data points, and displaying the 2D table in response to selection of the object by a user.

12. The method according to claim 11 , wherein producing the first visualization layer comprises displaying the object over the map.

13. The method according to claim 11 , wherein producing the first visualization layer comprises displaying the object in an additional 2D table.

14. The method according to claim 11 , wherein producing the first visualization layer comprises assigning to the object a representative data value that represents a calculated value corresponding to the clustered data points.
