Automated or partially automated anatomical surface assessment methods, devices and systems
Devices, systems and methods for assessing anatomical surface features are described herein. In some embodiments, a method of assessing a surface feature on a patient's skin surface includes (i) capturing one or more data sets from a patient's skin surface including the skin surface feature, and (ii) determining outline data of the skin surface feature based on at least one of the one or more data sets. The method can further include determining one or more confidence attributes associated with the determined outline data.
1. A method of assessing a surface feature on a patient's skin surface, including:
capturing one or more data sets from a patient's skin surface including the skin surface feature;
determining outline data of the skin surface feature based on at least one of the one or more data sets; and
determining one or more confidence attributes associated with the determined outline data;
wherein determination of the confidence attribute is based at least in part on one or more of:
distances between points in the determined outline data; and
distances between points in the determined or processed outline data and points in the one or more data sets.
2. A method as claimed in claim 1 , wherein at least one of the one or more confidence attributes include one or more of: a confidence attribute for the determined outline as a whole; a plurality of segment confidence attributes, each associated with a segment of the determined outline; and a plurality of point confidence attributes, each associated with a point on the determined outline.
3. A method as claimed in claim 2 , including rejecting the determined outline or part of the determined outline if one or more of the confidence attributes are unacceptable.
4. A method as claimed in claim 3 , including soliciting user input for replacement or modification of the rejected determined outline or rejected part of the determined outline.
5. A method as claimed in claim 1 , wherein the determined outline data includes sub-region outline data for one or more sub-regions of the surface feature.
6. A method as claimed in claim 5 , wherein the one or more confidence attributes include one or more of: one or more confidence attributes for the sub-region outline data for each of the one or more sub-regions; a plurality of sub-region segment confidence attributes, each associated with a segment of the determined sub-region outline data; and a plurality of sub-region point confidence attributes, each associated with a point in the determined sub-region outline data.
7. A method as claimed in claim 5 , including determining one or more tissue types associated with each of the sub-regions.
8. A method as claimed in claim 7 , including determining a tissue confidence attribute associated with the determined tissue type for each of the sub-regions.
9. A method as claimed in claim 1 including storing the one or more confidence attributes and/or data based on the one or more confidence attributes.
10. A method as claimed in claim 1 including displaying the one or more confidence attributes and/or data based on the one or more confidence attributes.
11. A method of assessing a surface feature on a patient's skin surface, including capturing one or more data sets from a patient's skin surface including the skin surface feature;
determining outline data of the skin surface feature based on at least one of the one or more data sets;
determining one or more confidence attributes associated with the determined outline data;
displaying at least part of an outline that is based at least in part on the determined outline data; and
displaying one or more visual representations of the one or more confidence attributes.
12. A method as claimed in claim 11 , including displaying a representation of the skin surface and/or skin surface feature.
13. A method as claimed in claim 11 , wherein displaying one or more visual representations of the one or more confidence attributes includes displaying one or more of: a numerical confidence indicator, a confidence symbol indicator, a colored confidence indicator, a patterned confidence indicator, and a confidence scale indicator.
14. A method as claimed in claim 11 , including displaying a plurality of visual representations of the one or more confidence attributes, at least some of the displayed visual representation being associated with segments of the displayed outline.
15. A method as claimed in claim 11 , wherein displaying at least part of an outline includes displaying only outline segments with confidence attributes that are acceptable.
16. A method as claimed in claim 11 , including enabling a user to modify the displayed outline or segments of the displayed outline,
determining one or more revised confidence attributes associated with the modified outline;
displaying the modified outline; and
displaying one or more visual representations of the one or more revised confidence attributes.
17. A method of assessing a surface feature on a patient's skin surface, including:
capturing one or more data sets from a patient's skin surface including the skin surface feature;
determining outline data of the skin surface feature based on at least one of the one or more data. sets, wherein the outline data includes a. first set of outline points; and
determining one or more confidence attributes associated with the determined outline data, wherein determination of the confidence attribute is based at least in part on one or more of: distances between points in the determined outline data; and
distances between points in the determined or processed outline data and points in the one or more data sets;
processing the outline data to produce a reduced set of outline points, the reduced set of outline points having a smaller number of outline points than the first set of outline points;
smoothing one or more of the first set of outline points and the reduced set of outline points.
18. A method as claimed in claim 17 , wherein at least one of the one or more confidence attributes include one or more of: a confidence attribute for the determined outline as a whole; a plurality of segment confidence attributes, each associated with a segment of the determined outline; and a plurality of point confidence attributes, each associated with a point on the determined outline.
19. A method as claimed in claim 18 , including rejecting the determined outline or part of the determined outline if one or more of the confidence attributes are unacceptable.
20. A method as claimed in claim 19 , including soliciting user input for replacement or modification of the rejected determined outline or rejected part of the determined outline.
