MECHANISM FOR ADVANCED STRUCTURE GENERATION AND EDITING

摘要

Embodiments of the present invention are directed to methods and a mechanism for manipulating images generated by radiotherapy machines used in radiation diagnostic and treatment applications. In one embodiment, a method is provided for intelligent automatic propagation of manual or automatic contouring across linked (e.g., registered) images and image data sets by acquiring one or more images of one or more image data sets; determining the correlation between the images with respect to identified structures; and generating a deformation map that establishes a correspondence for each point in the source image with a point in the target image. Subsequently, the intelligent propagation mechanism applies this deformation map individually to each structure of the source image and propagates the deformed structure to the target image.

1. A method for automatically propagating defined structures across data sets comprising:
accessing a first image, the first image comprising a first plurality of structures and a plurality of contoured effects; accessing a second image, the second image comprising a second plurality of structures corresponding to the first plurality of structures; generating a deformation map, the deformation map defining a relativity between the first and second pluralities of structures disposed on the first and second images, respectively; and based on the deformation map, automatically propagating the plurality of contoured effects comprised in the first image to the second image.
