Abstract

A method for localization of surgical target sites in the region of soft body parts, including the following steps: applying a number of artificial landmarks to the body part permitting sensing by a referencing system; referencing the surgical target site location relative to a landmark arrangement in a first position of the body part; sensing a new landmark arrangement in a changed second position of the soft body part; and mapping the dislocation or new location of the surgical target site by means of the information as to the dislocation or new arrangement of the landmarks.

Claims

1. A method for localization of a surgical target site in the region of a soft body part comprising the following steps:

applying a number of artificial landmarks to the soft body part thereby to permit sensing by a referencing system;

referencing the surgical target site location relative to a first arrangement of the landmarks in a first position of the soft body part;

sensing a second arrangement of the landmarks in a second position of the soft body part different from the first position of the soft body part; and

mapping the dislocation or new location of the surgical target site by using modeled structure data for the soft body part which relates changes within the interior of the soft body part to changes in the arrangement of the landmarks.

2. The method as set forth in claim 1, wherein at least three landmarks are applied to the soft body part.

3. The method as set forth in claim 2, wherein the second arrangement of the landmarks in said second position of said soft body part is sensed by a computer-controlled mapping system which monitors the surgery site.

4. The method as set forth in claim 2, wherein a lesion in the region of the female breast is localized.

5. The method as set forth in claim 1, wherein the referencing step includes using a CT, MRI, PET or SPECT mapping system to map the artificial landmarks and the structure of said soft body part.

6. The method as set forth in claim 5, wherein the second arrangement of the landmarks in said second position of said soft body part is sensed by a computer-controlled mapping system which monitors the surgery site.

7. The method as set forth in claim 5, wherein a lesion in the region of the female breast is localized.

8. The method as set forth in claim 1, wherein the second arrangement of the landmarks in said second position of said soft body part is sensed by a computer-controlled mapping system which monitors the surgery site.

9. The method as set forth in claim 8, wherein a lesion in the region of the female breast is localized.

10. The method as set forth in claim 1, wherein a lesion in the region of the female breast is localized.

11. The method as set forth in claim 1, wherein the dislocation or new location of the surgical target site is mapped continuously on a real-time basis and displayed in real time on a computer monitor.

12. The method as set forth in claim 11, wherein a lesion in the region of the female breast is localized.

13. The method as set forth in claim 1, wherein a lesion in the region of the female breast is localized.
