Abstract

Methods for assessing a skin surface of a patient and associated systems and devices are described herein. A method configured in accordance with embodiments of the present technology can include, for example, receiving a three-dimensional data set representative of the patient's skin surface and determining a boundary of a feature of the patient's skin in the three-dimensional data set. The method can further include determining, with a processor, a three-dimensional surface area of the feature within the boundary. In some embodiments, the method can also include identifying a plurality of sub-regions within the boundary and identifying one or more tissue types in each sub-region.

Core Innovation

The invention relates to displaying data representative of a feature on a skin surface of a patient over time by receiving a first data set captured at a first time and receiving a second data set captured at a second time. For each of the first data set and the second data set, the method determines a boundary of the feature, identifies a plurality of sub-regions within the boundary, and identifies one or more tissue types in each sub-region for the data set being processed.

Based on the first data set, the method displays a first representation of the feature that includes the feature, the boundary determined in the first data set, the sub-regions within the boundary identified in the first data set, and the one or more tissue types in each sub-region identified in the first data set. Based on the second data set, the method similarly displays a second representation that includes the feature, the boundary determined in the second data set, the sub-regions within the boundary identified in the second data set, and the one or more tissue types in each sub-region identified in the second data set.

The documented implementations additionally support generating a third representation using interpolation or extrapolation from the first and second data sets. The invention also supports visual representations in which additional indicator image data, including thermal, fluorescence, and/or texture image data, are overlaid on a three-dimensional model, and the display can include wound dimensions and a representation of tissue types such as viable tissue class and non-viable tissue class.

Claims Coverage

The partial claim set provided includes one independent claim that covers a method of displaying feature data on a skin surface over time using first and second captured data sets, with feature boundary determination, sub-region identification, tissue type identification per sub-region, and temporal display of corresponding representations.

Across the provided independent claim, the coverage centers on temporally displaying skin-surface feature information by tying together boundary determination, partitioning into sub-regions, tissue type identification per sub-region, and the generation of first and second representations that reflect the corresponding tissue and boundary information for each captured time point.
