Abstract

Methods, systems, and apparatuses are described for managing placement of transducer arrays on a subject/patient.

First claim

What is claimed is:

1. A method comprising:
generating a three-dimensional (3D) model of a portion of the subject's body;
determining, based on the 3D model and a plurality of simulated electrical field distributions, a plurality of transducer array layout maps, each transducer array layout map comprising:
a first pair of positions for placement of a first transducer array and a second transducer array; and
a second pair of positions for placement of a first transducer array and a second transducer array;

receiving a selection of a first transducer array layout map and a second transducer array layout map of the plurality of transducer array layout maps;
determining, based on the first transducer array layout map and the second transducer array layout map, an overlap condition between the first and second array layout maps, wherein the overlap condition indicates that one or both of the first and second pairs of positions of the first transducer array layout map are at the same position indicated on the 3D model as one or both of the first and second pairs of positions of the second transducer array layout map; and
causing display of the overlap condition.

2. The method of claim 1 , wherein generating the 3D model comprises:
causing one or more user devices to display a plurality of images of the portion of the subject's body;
receiving, based on a region-of-interest (ROI), a selection of one or more images of the plurality of images; and
generating, based on the one or more images, the 3D model.

3. The method of claim 2 , further comprising receiving, from a first user device of the one or more user devices, information associated with the ROI, and wherein receiving the selection of the one or more images comprises receiving the selection of the one or more images from a second user device of the one or more user devices.

4. The method of claim 1 , wherein determining the plurality of transducer array layout maps comprises:
determining, based on the 3D model, a plurality of pairs of positions for transducer array placement;
determining, for each pair of positions of the plurality of pairs positions, a simulated electrical field distribution of the plurality of simulated electrical field distributions; and
determining, based on the plurality of simulated electrical field distributions, the plurality of transducer array layout maps.

5. The method of claim 4 , wherein determining the simulated electrical field distribution for each pair of positions of the plurality of pairs positions comprises:
simulating, at a first position of the pair of positions, a first electrical field generated by a first transducer array;
simulating, at a second position of the pair of positions, a second electrical field generated by a second transducer array, wherein the second position is opposite the first position; and
determining, based on the first electrical field and the second electrical field, the simulated electrical field distribution.

6. The method of claim 1 , wherein causing display of the overlap condition comprises indicating the overlap condition on a user device by an audible sound, a notification, or both.

7. A method comprising:
generating a three-dimensional (3D) model of a portion of the subject's body;
determining, based on the 3D model and a plurality of simulated electrical field distributions, a plurality of transducer array layout maps, each transducer array layout map comprising:
a first pair of positions for placement of a first transducer array and a second transducer array; and
a second pair of positions for placement of a first transducer array and a second transducer array;

receiving a selection of a first transducer array layout map and a second transducer array layout map of the plurality of transducer array layout maps;
determining, based on the first transducer array layout map and the second transducer array layout map, an overlap condition between the first and second array layout maps, wherein the overlap condition indicates that one or both of the first and second pairs of positions of the first transducer array layout map are at substantially overlapping positions indicated on the 3D model as one or both of the first and second pairs of positions of the second transducer array layout map; and
causing display of the overlap condition.

8. The method of claim 7 , wherein the overlap condition indicates that one or both of the first and second pairs of positions of the first transducer array layout map satisfy a distance threshold with respect to one or both of the first and second pairs of positions of the second transducer array layout map.

9. The method of claim 7 , wherein the overlap condition indicates that one or both of the first and second pairs of positions of the first transducer array layout map are within a tolerance positioning range relative to one or both of the first and second pairs of positions of the second transducer array layout map.

10. A method, comprising:
presenting a plurality of images of an anatomic volume to at least one user;
accepting, from the at least one user, a selection of which images of the anatomic volume should be used to generate a plurality of transducer array layouts;
creating a model of electrical characteristics of the anatomic volume based on the selected images;
determining the plurality of transducer array layouts;
evaluating, based on the created model, which of the determined transducer array layouts satisfies at least one criterion;
presenting, to the at least one user, a plurality of transducer array layouts that satisfy the at least one criterion;
accepting, from the at least one user, a selection of one of the transducer array layouts that was presented to the at least one user; and
generating a report that describes the selected transducer array layout,
wherein the at least one user comprises a first user and a second user, wherein the method further comprises (a) accepting an input from the first user identifying a region of interest, and (b) outputting data describing the region of interest to the second user, and
wherein creating the model comprises, after outputting data describing the region of interest to the second user, performing segmentation based on input received from the second user regarding the region of interest.

11. The method of claim 10 , wherein the model of electrical characteristics of the anatomic volume is also based on at least one additional image.

12. The method of claim 10 , wherein creating the model comprises performing segmentation based on input received from the first user and the second user.

13. The method of claim 10 , wherein the method further comprises: (a) accepting an input from the first user identifying a gross segmentation; and (b) outputting data describing the gross segmentation to the second user.

14. The method of claim 13 , wherein creating the model comprises performing segmentation based on input received from the second user regarding the data describing the gross segmentation.

15. The method of claim 10 , wherein the method further comprises (a) accepting at least one note from the first user, and (b) outputting the at least one note to the second user.

16. The method of claim 15 , wherein creating the model comprises performing segmentation based on input received from the second user regarding the at least one note.

17. The method of claim 10 , wherein the method further comprises (a) accepting an input from the first user identifying an avoidance region, and (b) outputting data describing the avoidance region t
