Method and arrangement for automatically localizing organ segments in a three-dimensional image

A localization arrangement for automatically localizing organ segments in a three-dimensional image comprising:

• a means for providing a three-dimensional image of an organ comprising organ segments and at least one tubular network comprising a plurality of tubular structures;
• a separation means for automatic separation of the organ from other parts of the image;
• a tracing means for automatic tracing of the tubular network to obtain a branch map;
• an analysis means for automatic analysis of the branch map to identify specific tubular structures;
• an assignment means for automatic assignment regions of the organ to the specific tubular structures to segment the organ into localized organ segments;
• and
• an output for outputting the localized organ segments, the branch map and/or analyzed tubular network as image data.

A non-transitory computer readable medium storing computer program instructions for automatically localizing organ segments in a three-dimensional image, the computer program instructions when executed by a processor cause the processor to perform operations comprising:

• providing a three-dimensional image showing at least one organ and at least one tubular network comprising a plurality of tubular structures, the organ comprising organ segments;
• performing automatic separation of the organ from other parts of the image;
• performing automatic tracing of the tubular network to obtain a branch map;
• performing automatic analysis of the branch map to identify specific tubular structures;
• performing automatically assigning regions of the organ to the specific tubular structures to segment the organ into localized organ segments;
• and
• outputting the localized organ segments, the branch map, and/or analyzed tubular network as image data.
