## Abstract

Various examples are provided related to identification of anthropometric information for fitting of compression garments. In one example, a method of generating compression garment fit information includes acquiring images including a selected body part or body area in need of compression therapy; processing the acquired images along with a library of compression garment fit information; generating a 3D reconstruction of the selected body part/area; deriving anthropometric information for the selected body part/area from the 3D reconstruction; providing a compression value corresponding to a prescribed or intended amount of compression therapy applied to the selected body part/area; and generating compression garment fit information for the selected body part/area. In another example, a library of compression garment fit information includes anthropometric information generated for individuals in need of compression therapy; information associated with a health condition for the individuals; and compression garment fit instructions provided by a compression garment manufacturer.

## Claims

### Claim 1

A method for evaluating a first person for presence or absence of a health condition associated with a presence or absence of swelling on one or more body parts or body areas, the method comprising:
a) providing imaging information derived from imaging of one or more body parts or body areas of a first person in need of assessment for presence or absence of swelling in the first person's one or more body parts or body areas;
b) providing historical health information for the first person;
c) processing the first person imaging information and the historical health information, wherein the processing comprises:
i) providing a library of information generated from a plurality of persons, wherein the library comprises:
1) information derived from imaging of one or more body parts or body areas for each of the plurality of persons; and
2) a collection of historical health information for each of the plurality of persons;
ii) comparing the first person imaging information and the historical health information with the library of information;
iii) generating a determination of whether the first person exhibits a presence or absence of swelling in one or more of the first person's one or more body parts or body areas; and
iv) generating first person health condition information associated with the presence or absence of swelling in one or more of the first person's one or more body parts or body areas.

### Claim 2 (depends on 1)

The method of claim 1, further comprising:
a) incorporating the first person health condition information in the library of information for use in a subsequent determination of a presence or absence of swelling in a body part or body area for the first person or for another person.

### Claim 3 (depends on 1)

The method of claim 1, wherein the health condition comprises edema or lymphedema.

### Claim 4 (depends on 1)

The method of claim 1, further comprising generating compression garment fit information for the first person, wherein the compression garment fit information is derived from the first person imaging information and historical health information.

### Claim 5 (depends on 1)

The method of claim 1, wherein the first person imaging information includes mathematically accurate anthropometric measurements for one or more of the first person's one or more body parts or body areas.

### Claim 6 (depends on 1)

The method of claim 1, wherein when a determination that the first person is symptomatic for a health condition associated with swelling of a body part or body area, the method further comprises:
a) generating a recommendation that the first person wear a compression garment on the body part or body area associated with the swelling for a period of time; and
b) generating compression garment fit information for the body part or body area associated with the recommendation.

### Claim 7 (depends on 1)

The method of claim 1, wherein the historical health information is derived from medical records associated with the first person and each of the plurality of persons.

### Claim 8 (depends on 7)

The method of claim 7, wherein the historical health information for the first person further includes information provided by one or more of the first person, a family member of the first person, or a care giver of the first person.

### Claim 9 (depends on 1)

The method of claim 1, wherein when a determination that the first person exhibits a presence of swelling of a body part or body area, the method further comprises:
a) providing the first person with a treatment plan, wherein the treatment plan comprises directions for:
i) wearing of a compression garment on the body part or body area determined to have the presence of swelling; and
ii) one or more of:
1) a prescription for medication indicated for one or more health-related conditions associated with the presence of swelling in the body part or body area;
2) an exercise plan; and
3) a diet plan.

### Claim 10 (depends on 9)

The method of claim 9, wherein fit information for the compression garment is derived from the first person imaging information and first person health condition information.

### Claim 11 (depends on 9)

The method of claim 9, wherein:
a) the treatment plan is indicated for the first person from a first time to a second time; and
b) after the second time, the first person is evaluated by a medical provider to generate information associated with a presence or absence of an improvement in an amount of swelling in the first person's body part or body area.

### Claim 12 (depends on 11)

The method of claim 11, wherein the information associated with the presence or absence of the improvement is incorporated in the library of information for subsequent use in a determination of a presence or absence of swelling in a body part or body area for the first person or for a second person.

### Claim 13 (depends on 11)

The method of claim 11, wherein the information associated with the presence or absence of the improvement in the first person's body part or body area is used to generate a treatment plan for a second person determined to exhibit a presence of swelling in a body part or body area.

### Claim 14 (depends on 11)

The method of claim 11, wherein between the first and second times, first person information is provided by one or more sensors associated with the first person, thereby generating information associated with a presence or absence of compliance with the treatment plan.

### Claim 15 (depends on 14)

The method of claim 14, wherein the one or more sensors are configured in a wearable device.

### Claim 16 (depends on 1)

The method of claim 1, wherein the generated first person health condition information is used to validate or modify existing information associated with one or more of the first person:
a) anthropometry;
b) physiology;
c) compression garment fit determination;
d) medical diagnosis;
e) physical condition; and
f) medical treatment effects.

### Claim 17 (depends on 1)

The method of claim 1, wherein the first person's one or more body parts or body areas comprises one or both legs.

### Claim 18 (depends on 1)

The method of claim 1, wherein the first person's one or more body parts or body areas comprises one or both arms.

### Claim 19 (depends on 1)

The method of claim 1, wherein the first person's one or more body parts or body areas comprises one or both hands.

### Claim 20 (depends on 1)

The method of claim 1, wherein the imaging information for each of the plurality of persons is derived from images generated from one or more of:
a) one or both legs;
b) one or both arms; or
c) one or more hands.
