초록 ▼

A method is provided for determining a position of an object within a breast of a female patient in a simple manner from a three-dimensional image taken of the breast. A simplified model is made of an internal structure of a breast having glandular bodies leading via lactiferous ducts to an outlet at a nipple. A particularly advantageous model is a tree-type structure in which branches correspond to lactiferous ducts and leaves correspond to glandular bodies. Furthermore, a determination is made of whether the object has contact with an element of the tree-type structure. Alternatively, a distance to an element of the tree-type structure is established. By correlating tree-type structures derived from various images taken on the same breast, the location of the object can be unequivocally established.

1. An X-ray machine having a non-transitory computer-readable medium encoded with program instructions which, when executed by a processor of the x-ray machine, comprises: producing a three-dimensional image of a breast;identifying lactiferous ducts and associated glandular bodies in the image;determining a position of an object relative to at least one of the lactiferous ducts and glandular bodies;recording the relative position in the computer-readable medium; andthereafter re-determining the position of the object from the previously recorded relative position even through orientation or configuration of the breast has changed. 2. The X-ray machine according to claim 1, wherein the three-dimensional image of the breast is produced with at least one of an X-ray computer tomography machine, an ultrasound scanner, and a nuclear spin tomograph. 3. The X-ray machine according to claim 1, further comprising identifying a nipple in the image prior to, subsequent, or during the step of identifying the lactiferous ducts and associated glandular bodies in the image. 4. The method X-ray machine according to claim 3, wherein identifying the nipple comprises contour segmentation of the breast and identification of the nipple on a basis of geometrical estimates. 5. The X-ray machine according to claim 1, wherein identifying lactiferous ducts and associated glandular bodies comprises threshold value segmentation of lactiferous ducts and geometrical segmentation of lactiferous ducts and glandular bodies. 6. The X-ray machine according to claim 1, wherein identifying lactiferous ducts and associated glandular bodies comprises utilizing a Snakes algorithm or another contour finding algorithm. 7. The X-ray machine according to claim 1, wherein determining a position of an object comprises establishing at least one feature of a spatial relationship between the object and at least one of the lactiferous ducts and glandular bodies. 8. The X-ray machine according to claim 7, wherein determining a position of an object comprises identifying at least one of the lactiferous ducts and glandular bodies with which the object has contact. 9. The X-ray machine according to claim 7, wherein determining a position of an object comprises determining a distance of the object from at least one of the lactiferous ducts and glandular bodies. 10. The X-ray machine according to claim 9, wherein the distance is established with respect to a center of mass of one of glandular bodies. 11. The X-ray machine according to claim 1, further comprising transposing the image to a simplified model subsequent to the step of identifying the lactiferous ducts and the associated glandular bodies. 12. The X-ray machine according to claim 11, wherein the simplified model is a tree-type data structure, with branches of the tree-type structure corresponding to lactiferous ducts, and leaves of the tree-type structure corresponding to glandular bodies. 13. The X-ray machine according to claim 1, further comprising: producing a different three-dimensional image of the breast;identifying lactiferous ducts and associated glandular bodies in the different image;determining a position of the object within the different image relative to at least one of the lactiferous ducts and glandular bodies in the different image; andfusing data of the three-dimensional images to coincide the determined positions of the object. 14. An X-ray machine comprising a non-transitory computer-readable medium encoded with program instructions which, when executed by a processor of the X-ray machine, comprises: producing a three-dimensional image of a breast;identifying lactiferous ducts and associated glandular bodies in the image;determining a position of an object within the breast relative to at least one of the lactiferous ducts and glandular bodies; andgenerating data of a model representing the identified lactiferous ducts and associated glandular bodies in the image and the determined position of the object related to at least one of the lactiferous ducts and glandular bodies. 15. The X-ray machine according to claim 14, wherein the program instructions are further executable by the processor for identifying a nipple in the image prior to, subsequent, or during the step of identifying the lactiferous ducts and associated glandular bodies in the image. 16. The X-ray machine according to claim 15, wherein the program instructions for identifying the nipple comprise program instructions for contour segmentation of the breast and identification of the nipple on a basis of geometrical estimates. 17. The X-ray machine according to claim 14, wherein the program instructions for identifying lactiferous ducts and associated glandular bodies comprise program instructions threshold value segmentation of lactiferous ducts and geometrical segmentation of lactiferous ducts and glandular bodies. 18. The X-ray machine according to claim 14, wherein the program instructions for identifying lactiferous ducts and associated glandular bodies comprise a Snake algorithm or another contour finding algorithm. 19. The X-ray machine according to claim 14, wherein the program instructions for determining the position of the object comprise program instructions for establishing at least one feature of a spatial relationship between the object and at least one of the lactiferous ducts and glandular bodies.
