Device and method for localizing an object of interest in a subject

A method for localizing an object of interest in a subject comprising the acts of:

• registering a three-dimensional representation of the subject, which comprises a plurality of segments corresponding to a plurality of structural regions of the subject, with a two-dimensional image, thereby defining a plurality of areas in the image corresponding to the plurality of segments such that at least one area of the plurality of areas is associated with a respective region of the plurality of structural regions;
• displaying the plurality of areas in the image;
• and
• localizing the object by extracting an indication of the object from the image by processing the image registered with the three-dimensional representation;
• and
• increasing an accuracy of localizing the object with reduced computation power or computation time by limiting the processing of the image registered with the three-dimensional representation to an object area of the plurality of areas which is associated with a predetermined object region.

A non-transitory computer readable medium embodying computer instructions which, when executed by a processor, configure the processor to perform the acts of:

• registering a three-dimensional representation of the subject, which comprises a plurality of segments corresponding to a plurality of structural regions of the subject, with a two-dimensional image, thereby defining a plurality of areas in the image corresponding to the plurality of segments such that at least one area of the plurality of areas is associated with a respective region of the plurality of structural regions;
• displaying the plurality of areas in the image;
• and
• localizing the object by extracting an indication of the object from the image by processing the image registered with the three-dimensional representation;
• and
• increasing an accuracy of localizing the object with reduced computation power or computation time by limiting the processing of the image to an object area of the plurality of areas which is associated with a predetermined object region.
