Abstract

A compression paddle with a plurality of markers is advanced towards a patient's breast which has been positioned on a support platform for an imaging procedure. An initial position of the compression paddle is detected relative to the support platform when a portion of the breast is contacted. An initial marker is identified which is associated with a feature of the breast when the compression paddle is in the initial position. A compression target marker is based at least in part on the initial position and the initial marker.

First claim

What is claimed is:

1. A method of compressing a breast for an imaging procedure, the method comprising:
advancing a compression paddle towards the breast positioned on a support platform, wherein the compression paddle comprises a plurality of markers disposed thereon;
contacting at least a portion of the breast with the compression paddle;
detecting, based on the contacting, an initial position of the compression paddle relative to the support platform;
identifying an initial marker of the plurality of markers, wherein the initial marker is associated with a feature of the breast when the compression paddle is in the initial position; and
determining a compression target marker of the plurality of markers based at least in part on the initial position and the initial marker.

2. The method of claim 1 , further comprising terminating compression of the breast when the feature of the breast is associated with the compression target marker.

3. The method of claim 1 , further comprising, after the determining operation:
initiating a target compression of the breast;
monitoring a condition of the breast; and
terminating the target compression when the condition reaches a predetermined condition.

4. The method of claim 1 , wherein each of the plurality of markers are positioned on the compression paddle at a plurality of distances from a leading edge of the compression paddle.

5. The method of claim 1 , wherein the plurality of markers comprise automatic exposure markers.

6. The method of claim 1 , wherein the feature of the breast comprises at least one of a nipple, a skin line, a chest wall, and an axilla tissue.

7. The method of claim 1 , the determining operation comprises comparing at least one of the initial marker and the initial position to a test dataset.

8. The method of claim 7 , wherein the test dataset comprises information obtained from prior compressions of a plurality of breasts.

9. The method of claim 1 , wherein the initial marker comprises a marker disposed on the breast.

10. The method of claim 3 , further wherein the predetermined condition is a minimum compressed thickness.

11. The method of claim 3 , further wherein the predetermined condition is a rate of change of a condition.

12. The method of claim 11 , wherein the rate of change of the condition is no change of the condition.

13. The method of claim 3 , further comprising subsequent to the terminating operation, imaging the breast.

14. The method of claim 1 , further comprising receiving from a sensor, a data signal associated with the initial marker.

15. The method of claim 14 , further comprising comparing the received data signal to a known data to determine the compression target marker.
