Abstract

An imaging device for monitoring a skin feature includes a camera, at least one processor and memory. The imaging device displays a body area guide, receives a selection of a body area, initiates an image sequence of the body area, the image sequence including capturing, using the camera, a plurality of images, determines whether all body areas have been imaged, analyzes the images, and provides the analyzed images to a clinician. The imaging device can be part of a system including a server in communication with a monitor, where the clinician views the images on the monitor. Additionally, each skin feature can be ranked in order of risk and presented to the clinician in that order.

Claims (34)

1. A skin feature review system, comprising:

at least one processor;

a database storing previous data of a plurality of skin features of a patient, wherein the previous data include a reference image of each of the plurality of skin features and metadata, the metadata including an analysis of at least one characteristic of the skin features; and

memory comprising computer-executable instructions that, when executed by the at least one processor, cause the at least one processor to:

receive images of the plurality of skin features;

analyze the images of the plurality of skin features by comparing the images to the reference images included in the database;

provide one or more results of the analysis, wherein the one or more results of the analysis include at least a risk ranking;

use the risk ranking to determine a highest-risk skin feature; and

generate, based on the risk ranking, a listing of the plurality of skin features in order of the highest-risk skin feature to lowest risk.

2. The system of claim 1 , wherein the results include differential images displayed based on the risk ranking.

3. The system of claim 1 , wherein the results include time evolution images displayed based on a user selection.

4. The system of claim 1 , wherein the risk ranking is generated based on ratings for symmetry, border, color, size, and evolution.

5. The system of claim 1 , wherein the results include an image of a skin feature for which there is a reference image.

6. The system of claim 5 , wherein the skin feature for which there is the reference image has been biopsied.

7. The system of claim 5 , wherein the memory further encodes computer executable instructions that, when executed by the at least one processor, cause the at least one processor to:

receive a clinical result about the skin feature; and

update the database to include the skin feature and the clinical result.

8. The system of claim 1 , wherein the results include an image of a skin feature and the memory further encodes computer executable instructions that, when executed by the at least one processor, cause the at least one processor to:

receive an annotation for the image of the skin feature, the annotation being at least one of: a diagnosis, a biopsy result, and a recommended review interval; and

add the annotation to the metadata of the image of the skin feature in the database.

9. A system for analyzing images of skin features, comprising:

at least one processor;

a database; and

memory comprising computer-executable instructions that, when executed by the at least one processor, cause the at least one processor to:

receive an image of a skin feature;

analyze the skin feature for at least one aspect of a plurality of aspects including: symmetry, border, color, diameter, evolution, and height;

identify a reference skin feature in the database, wherein the at least one aspect of the reference skin feature was previously analyzed;

compare the at least one aspect of the skin feature to the at least one aspect of the reference skin feature;

determine a risk ranking of the skin feature based on the comparison;

use the risk ranking to determine a highest-risk skin feature; and

generate guidance to a clinician based on the risk ranking, wherein the guidance includes a listing of skin features in order of the highest-risk skin feature to lowest risk.

10. The system of claim 9 , wherein the guidance includes instructions to monitor the skin feature over time.

11. The system of claim 9 , wherein the image of the skin feature is a composite image generated by combining multiple adjacent images into a larger image.

12. The system of claim 9 , wherein the database includes a time-series of differential images of the reference skin feature.
