Abstract
A two-dimensional contouring tool that allows a user to maintain a minimum distance away (in 3D) from other structures. The contouring tool allows the user to rapidly define a series of contours that conform to the shape of one or more existing contours (or targets) with user-specified margin limits between the new contour and the existing contours (or targets).
Claims18
A method of contouring an image, the method comprising:
- acquiring an image of a patient;
- generating, at a processor, a first contour around a sensitive structure in the image;
- defining, at a processor, a distance to be maintained from the first contour in the image;
- defining a perimeter at least partially around the sensitive structure based on the distance;
- and
- applying, at a processor, a second contour on the image at least partially around a target structure for receiving radiation while limiting the second contour of the target structure in substantially real-time to not infringe the perimeter of the sensitive structure.

A method of contouring an image, the method comprising:
- generating, at a processor, a treatment plan for a patient, the treatment plan including a first image;
- generating, at a processor, a first contour around a sensitive structure in the first image;
- defining, at a processor, a distance to be maintained from the first contour in the first image;
- defining a perimeter at least partially around the sensitive structure based on the distance;
- applying, at a processor, a second contour at least partially around a target structure in the first image;
- acquiring, at a processor, a second image of the patient while in substantially a treatment position;
- and
- applying, at a processor, a constraint defined for the sensitive structure from the first image to the second image when contouring the target structure in the second image.
