Abstract
Using a computer-implemented intermediary by which contouring performed by two participants, such as two physicians, can be compared. First, contouring performed by each participant can be compared to contouring performed by the intermediary. Then, by way of the common intermediary and a transitive analysis, contouring performed by each participant can be compared.
Claims19
A computer-readable storage device comprising instructions, that when executed by at least one processor, configure the at least one processor to:
- present a user interface, wherein the user interface simultaneously displays in three spatially distinct and visually distinguishable portions:
- a first portion configured to display data of a first representation of a volume that is not present in a first contouring, generated by a first human participant, of a target or an organ at risk of a first group of subjects but present in a second contouring, generated by a second human participant, of a target or an organ at risk of a second group of subjects;
- a second portion configured to display data of a second representation of a volume that is present in the first contouring but not present in the second contouring;
- and
- a third portion configured to display data of a third representation of a volume that is shared by both the first contouring and the second contouring,
- wherein each of the first, second, and third portions is visually distinguished from the others by at least one of color, shading, or pattern, and the user interface is configured to concurrently present these representations to facilitate direct visual comparison of volumetric differences and commonalities between the first and second contourings,
- wherein the first, second, and third portions are displayed as part of a graph having an x-axis representing distance error and a y-axis representing a volume or count of voxels at each distance error, and
- wherein the first contouring and the second contouring are generated by different human participants on different image datasets, such that the comparison does not require the different human participants to contour a shared image dataset.

A computer-implemented method of comparing image contouring by different human participants without requiring that the different participants contour a shared image dataset, the method comprising:
- presenting a user interface, wherein the user interface simultaneously displays in three spatially distinct and visually distinguishable portions includes:
- a first portion configured to display data of a first representation of a volume that is not present in a first contouring, generated by a first human participant, of a target or an organ at risk of a first group of subjects but present in a second contouring, generated by a second human participant, of a target or an organ at risk of a second group of subjects;
- a second portion configured to display data of a second representation of a volume that is present in the first contouring but not present in the second contouring;
- and
- a third portion configured to display data of a third representation of a volume that is shared by both the first contouring and the second contouring,
- wherein each of the first, second, and third portions is visually distinguished from the others by at least one of color, shading, or pattern, and the user interface is configured to concurrently present these representations to facilitate direct visual comparison of volumetric differences and commonalities between the first and second contourings,
- wherein the first, second, and third portions are displayed as part of a graph having an x-axis representing distance error and a y-axis representing a volume or count of voxels at each distance error, and
- wherein the first contouring and the second contouring are generated by different human participants on different image datasets, such that the comparison does not require the different human participants to contour a shared image dataset.

- a second portion configured to display data of a second representation of a volume that is present in the first contouring but not present in the second contouring;
- or
- a third portion configured to display data of a third representation of a volume that is shared by both the first contouring and the second contouring,
- wherein each of the first, second, and third portions is visually distinguished from the others by at least one of color, shading, or pattern, and the user interface is configured to concurrently present these representations to facilitate direct visual comparison of volumetric differences and commonalities between the first and second contourings,
- wherein the first, second, and third portions are displayed as part of a graph having an x-axis representing distance error and a y-axis representing a volume or count of voxels at each distance error, and
- wherein the first contouring and the second contouring are generated by different human participants on different image datasets, such that the comparison does not require the different human participants to contour a shared image dataset.
