Location-sensitive cursor control and its use for vessel analysis
First Claim
1. A method, comprising:
- displaying an image of one or more lumens of a subject;
automatically identifying one or more lumens in the image;
designating as lumen envelopes, portions of the image in vicinities of respective lumens; and
in response to a user designating a location inside a lumen envelope of a given lumen, via an input device, the location corresponding to a given longitudinal location within the given lumen,generating a feature on the image that corresponds to the given longitudinal location; and
displaying an output in response to the generated feature.

Abstract
Apparatus and methods are provided, including displaying an image of one or more lumens of a subject. A processor includes lumen-identification functionality configured to automatically identify one or more lumens in the image. Envelope-designation functionality of the processor designates as lumen envelopes, portions of the image in vicinities of respective lumens. In response to the user designating a location inside a lumen envelope of a given lumen, via an input device, the location corresponding to a given longitudinal location within the given lumen, feature-generation functionality of the processor generates a feature on the image that corresponds to the given longitudinal location. An output is displayed in response to the generated feature. Other embodiments are also described.

14. A method, comprising:
-
displaying an image of lumens of a subject'"'"'s body; automatically identifying a plurality of lumens in the image; designating as lumen envelopes, portions of the image in the vicinity of respective lumens; and in response to the user designating a location inside a lumen envelope of a given lumen, via the input device, automatically identifying a segment of the given lumen that corresponds to the location; and displaying an output in response to the identified segment. - View Dependent Claims (15, 16, 17)

20. A method, comprising:
-
displaying an image of lumens of a subject'"'"'s body; displaying a feature in the image, in a vicinity of one of the lumens on the image; receiving an input from a user, via an input device, indicating that the feature should be moved; and in response to receiving the input, only allowing movement of the feature along directions of paths of the lumens, wherein the feature includes a cursor, and wherein only allowing movement of the feature along directions of paths of the lumens comprises only allowing movement of the cursor along the directions of the paths of lumens. - View Dependent Claims (21, 22, 23, 24)

25. A method, comprising:
-
displaying an image of lumens of a subject'"'"'s body; in response to a user moving a cursor to a given location on the image via an input device, automatically identifying a lumen in the image, by interpreting the movement of the cursor to the location as indicating that there is a greater probability that there is a lumen in the vicinity of the location of the cursor than in another portion of the image; and displaying an output in response to the identified lumen, wherein; identifying the lumen comprises assigning vesselness values to respective regions of the image, the vesselness values indicating probabilities that respective regions correspond to a lumen, and interpreting the movement of the cursor comprises assigning different weightings to vesselness values of regions in the vicinity of the location of the cursor from weightings assigned to vesselness values of regions in the other portion of the image.
