Mechanism for advanced structure generation and editing

A method for propagating updated structural contouring data among a plurality of data sets, the method comprising:

• acquiring initial image data of a plurality of anatomical structures, the initial image data being acquired using an a medical imaging system;
• receiving, via a user interface of a computing system, user input corresponding to a contouring data of the plurality of anatomical structures in the initial image data;
• editing the plurality of anatomical structures in the initial image data according to contouring data;
• acquiring, using the medical imaging system, updated image data of the plurality of anatomical structures in an updated image data set;
• establishing a relationship between the updated image data and the initial image data in the computing system;
• generating a deformation map in a processor of the computing system, the deformation map defining structural deviation between the initial image data and the updated image data by comparing a first plurality of pixels comprising the initial image data to a second plurality of pixels comprising the updated image data to determine a presence of structural deviation between the initial image data and the updated image data based on a relativity between the first and second plurality of pixels;
• and
• based on the deformation map, using the processor of the computing system to propagate the contour data comprised in the initial image data to the updated image data,
• wherein the relativity between the first plurality of pixels to the second plurality of pixels comprises a relativity between a first plurality of pixel intensities corresponding to a feature comprised in the first plurality of pixels and a second plurality of pixel intensities corresponding to the same feature comprised in the second plurality of pixels.

A radiation therapy device comprising:

• one or more radiation sources;
• one or more imagers configured to receive radiation from the one or more radiation sources, and to generate data representing a target image comprising one or more anatomical structures;
• and
• a computing device configured to access data representing a source image comprising manual contouring and a deformation map mapping a relativity between a first plurality of pixels comprising the source image to a second plurality of pixels comprising the data image, wherein the manual contouring is automatically propagated while taking into account the deformation map,
• wherein the relativity between the first plurality of pixels to the second plurality of pixels comprises a relativity between a first plurality of pixel intensities corresponding to a feature comprised in the first plurality of pixels and a second plurality of pixel intensities corresponding to the same feature comprised in the second plurality of pixels.
