Abstract

The present disclosure involves an electronic device for visualizing a sensation experienced by a patient. The electronic device includes a touchscreen display configured to receive a tactile input from a user and display a visual output. The electronic device includes a memory storage component configured to store programming code. The electronic device includes a computer processor configured to execute the programming code to perform the following tasks: generating, in response to the tactile input from the user, a three-dimensional (3D) sensation map that represents the sensation experienced by the patient; deriving a two-dimensional (2D) sensation map based on the 3D sensation map, wherein the 2D sensation map contains substantially less data than the 3D sensation map; and sending the 2D sensation map over a network to facilitate a reconstruction of the 3D sensation map using the 2D sensation map.

First claim

What is claimed is:

1. An electronic device for visualizing a sensation experienced by a patient, the electronic device comprising:
a user interface configured to receive a tactile input from a user and display a visual output;
a memory storage component configured to store programming code; and
a computer processor configured to execute the programming code to perform the following tasks:
selecting, in response to a user input and from an electronic database offering a plurality of predefined human body models that each have a unique set of physical characteristics, a human body model that most closely matches physical characteristics of the patient;
offering, via the user interface, the user one or more options on adjusting one or more of the physical characteristics of the selected human body model;
detecting, via the user interface, an adjustment of a physical characteristic of the selected human body model;
adjusting, in response to the detected adjustment, the physical characteristic of the selected human body model;
generating, in response to the tactile input from the user, a three-dimensional (3D) sensation map over the selected human body model having the adjusted physical characteristic, the 3D sensation map including a pain map representing a pain sensation experienced by the patient and a stimulation map representing a stimulation sensation experienced by the patient;
displaying an area of the pain map that is not covered by the stimulation map without displaying an overlapped area between the pain map and the stimulation map;
deriving a two-dimensional (2D) sensation map based on the 3D sensation map, wherein the 2D sensation map contains substantially less data than the 3D sensation map; and
sending the 2D sensation map over a network to facilitate a reconstruction of the 3D sensation map using the 2D sensation map and the selected human body model having the adjusted physical characteristic.

2. The electronic device of claim 1 , wherein the deriving the 2D sensation map comprises deriving a snapshot type 2D sensation map that includes a projection of the 3D sensation map on a flat surface.

3. The electronic device of claim 1 , wherein the deriving the 2D sensation map comprises deriving a wrapping texture type 2D sensation map, the wrapping texture type 2D sensation map including a 2D digital cloth configured to be wrapped around a 3D human body model, and wherein the 2D digital cloth contains one or more sensation regions drawn by the patient.

4. The electronic device of claim 3 , wherein the sending the 2D sensation map comprises saving the 2D digital cloth to a remote electronic database, and wherein the 2D digital cloth is configured for downloading by one of the electronic devices on which the 3D sensation map is to be reconstructed.

5. The electronic device of claim 1 , wherein the tasks further comprise:
receiving a further 2D sensation map; and
reconstructing a further 3D sensation map using the further 2D sensation map.

6. The electronic device of claim 1 ,
wherein the pain map is a 3D pain map that includes a 3D visualization of a pain experienced by the patient in a first body region of the patient; and
wherein the stimulation map is a 3D stimulation map that includes a 3D visualization of a stimulation experienced by the patient in a second body region of the patient.

7. The electronic device of claim 1 , wherein the electronic device is one of: a clinician programmer, a patient programmer, and a computer tablet, and wherein the electronic device is portable and is configured to communicate with external devices according to a wired or wireless communications protocol.

8. A medical system, comprising:
an electronic database storing a plurality of predefined human body models that each have a unique set of physical characteristics;
a first portable electronic device that includes:
a user interface configured to receive a tactile input from a user and display a visual output;
a first electronic processing component configured to:
select, from the electronic database in response to a user input, one of the predefined human body models that most closely matches physical characteristics of a patient;
offer, via the user interface, the user one or more options on adjusting one or more of the physical characteristics of the selected human body model;
detect, via the user interface, an adjustment of a physical characteristic of the selected human body model;
adjust, in response to the detected adjustment, the physical characteristic of the selected human body model;
generate a three-dimensional (3D) sensation map over the selected human body model having the adjusted characteristic, the sensation map including a pain map representing a pain sensation experienced by the patient and a stimulation map representing a stimulation sensation experienced by the patient;
displaying an area of the pain map that is not covered by the stimulation map without displaying an overlapped area between the pain map and the stimulation map;
produce a two-dimensional (2D) sensation map that is a 2D representation of the 3D sensation map for the patient, the 2D sensation map containing less data than the 3D sensation map; and

a first communications interface configured to send the 2D sensation map to the electronic database; and

a second portable electronic device that includes:
a second communications interface configured to receive the 2D sensation map and the selected human body model from the electronic database;
a second electronic processing component configured to reproduce the 3D sensation map based on the 2D sensation map and the selected human body model; and
a second user interface configured to display at least one of the 2D sensation map received from the electronic database or the reproduced 3D sensation map.

9. The medical system of claim 8 , wherein the 2D sensation map includes a snapshot type 2D sensation map that is a projection of the 3D sensation map on a flat surface.

10. The medical system of claim 8 , wherein the 2D sensation map include a wrapping texture type 2D sensation map, the wrapping texture type 2D sensation map including a 2D digital cloth configured to be wrapped around a 3D human body model, and wherein the 2D digital cloth contains one or more sensation regions drawn by the patient.

11. The medical system of claim 8 ,
wherein the pain map is a 3D pain map that includes a 3D visualization of a pain experienced by the patient in a first body region of the patient; and
wherein the stimulation map is a 3D stimulation map that includes a 3D visualization of a stimulation experienced by the patient in a second body region of the patient.
