Abstract
System and method for labeling a tubular structure. A tubular structure is first displayed on a display screen. A representation of the tubular structure can be obtained. A user draws a curve on the display screen using an electronic pen that is associated with a label. Based on the user drawn curve, one or more segments of the tubular structure that corresponds to the drawn curve are identified based on the representation of the segmented tubular structure. The label is then assigned to such identified one or more segments of the tubular structure.
Claims30
A method for labeling a tubular structure on a display screen of a device, comprising steps of:
- displaying a tubular structure on a display screen;
- obtaining a representation of the tubular structure;
- displaying a curve on the display screen based on information received from a user who draws the curve on the display screen using an electronic pen associated with a label;
- identifying one or more segments of the tubular structure that corresponds to the drawn curve based on the representation of the segmented tubular structure;
- and
- assigning the label to the one or more segments of the tubular structure.
A system for labeling a tubular structure on a display screen of a device, comprising:
- a display device having a display screen;
- a display unit configured for displaying a tubular structure on a display screen;
- a tubular structure representation generation unit configured for obtaining a representation of the tubular structure;
- an interactive drawings unit configured for enabling a user to draw a curve on the display screen using an electronic pen associated with a label;
- a tubular segment extraction unit configured for identifying one or more segments of the tubular structure that corresponds to the drawn curve based on the representation of the segmented tubular structure;
- and
- a label assignment unit configured for assigning the selected label to the one or more segments of the tubular structure.
