Abstract

Systems and methods for locating abnormalities within a breast and generating mappings of structures, such as ducts, within the breast. First imaging data may be acquired for a breast from a first imaging modality and second imaging data for the breast from a second imaging modality. The first imaging data is co-registered with the second imaging data, such that the first imaging data and the second imaging data share a common coordinate space. Based on the second imaging data, a plurality of structures within the breast are mapped to generate a mapping of the plurality of structures. From at least one of the first imaging data or the second imaging data, the abnormality in the breast is located. The mapping of the plurality of structures and the located abnormality in the breast may be concurrently displayed. A statistical analysis of the mapping of the breast structures may also be performed.

First claim

1 . A method for locating an abnormality within a breast, the method comprising:
acquiring first imaging data for the breast from a first imaging modality, wherein the first imaging modality is at least one of an x-ray-based imaging modality or a magnetic resonance imaging (MRI) modality; acquiring second imaging data for the breast from a second imaging modality, wherein the second imaging modality is at least one of an ultrasound imaging modality or a thermal imaging modality; based on the second imaging data from the second imaging modality, generating a mapping of one or more structures within the breast; locating, from at least one of the first imaging data or the second imaging data, the abnormality in the breast; and based at least on the generated mapping of the one or more structures, determining a location of the abnormality relative to the mapped one or more structures within the breast.

2 . The method of claim 1 , further comprising displaying at least a portion of a visual representation of the model mapped one or more structures concurrently with the abnormality.

3 . The method of claim 1 , wherein the one or more structures are breast ducts.

4 . The method of claim 1 , wherein the one or more structures are at least one of breast ducts, lobules, lymph nodes, vascular structures, or Cooper's ligaments.

5 . The method of claim 1 , wherein determining the location of abnormality relative to the mapped one or more structures within the breast includes determining whether the abnormality is within one of the one or more structures.

6 . The method of claim 1 , wherein the first imaging data is three-dimensional imaging data acquired from one of tomosynthesis, computed tomography, or MRI.

7 . The method of claim 1 , wherein the first imaging data is mammogram data and the second imaging data is ultrasound imaging data.

8 . The method of claim 1 , further comprising co-registering the first imaging data from the first imaging modality with the second imaging data from the second imaging modality, such that the first imaging data from the first imaging modality and the second imaging data from the second imaging modality share a common coordinate space.

9 - 20 . (canceled)

21 . The method of claim 1 , wherein generating the mapping of the one or more structures within the breast includes identifying the one or more structures within the breast using an artificial image analysis technique on the second imaging data.

22 . The method of claim 21 , wherein generating the mapping of the one or more structures within the breast further includes removing tissue of the breast other than the identified one or more structures.

23 . The method of claim 1 , wherein the one or more structures are breast ducts and generating the mapping of the breast ducts within the breast includes identifying the breast ducts within the breast and removing non-ductal tissue.

24 . The method of claim 1 , wherein generating the mapping of the one or more structures within the breast includes:
identifying a first structure within the breast and generating a first mapping of the first structure; and identifying a second structure different than the first structure within the breast and generating a second mapping of the second structure.

25 . The method of claim 1 , further comprising identifying a risk of the abnormality based on the determined location of the abnormality relative to the mapped one or more structures within the breast.

26 . A system for locating an abnormality within a breast, the system comprising:
at least one processor; and memory, operatively connected to the at least one processor, storing instructions that when executed by the at lest one processor cause the system to perform a set of operations comprising:
receiving first imaging data for the breast from a first imaging modality, wherein the first imaging modality is at least one of an x-ray-based imaging modality or a magnetic resonance imaging (MRI) modality;
receiving second imaging data for the breast from a second imaging modality, wherein the second imaging modality is at least one of an ultrasound imaging modality or a thermal imaging modality;
based on the second imaging data from the second imaging modality, generating a mopping of one or more structures within the breast;
locating, from at least one of the first imaging data or the second imaging data, the abnormality in the breast; and
based at least on the mapping of the one or more structures, determining a location of the abnormality relative to the mapped one or more structures within the breast.

27 . The system of claim 26 , wherein the system further includes a display, the set of operations that the system performs further comprises displaying at least a portion of a visual representation of the mapped one or more structures concurrently with the abnormality.

28 . The system of claim 26 , wherein the one or more structures are at least one of breast ducts, lobules, lymph nodes, vascular structures, or Cooper's ligaments.

29 . The system of claim 26 , wherein the set of operations that the system performs further comprises determining whether the abnormality is within one of the one or more structures.

30 . The system of claim 26 , wherein the first imaging data is three-dimensional imaging data acquired from one of tomosynthesis, computed tomography, or MRI.

31 . The system of claim 26 , wherein the first imaging data is mammogram data and the second imaging data is ultrasound imaging data.

32 . The system of claim 26 , wherein the set of operations that the system performs further comprises co-registering the first imaging data from the first imaging modality with the second imaging data from the second imaging modality, such that the first imaging data from the first imaging modality and the second imaging data from the second imaging modality share a common coordinate space.
