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.

28. 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. - View Dependent Claims (29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40)

41. 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 (42, 43, 44, 45, 46)

47. 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. - View Dependent Claims (48, 49, 50, 51, 52)

53. 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. - View Dependent Claims (54)
