Abstract

A method and a control module for calculating and displaying result data based on at least one medical image, which has been captured by an imaging device, are provided. At least one image is captured by the imaging device in a digital format with a plurality of bone fragments. Subsequently, a segmentation method is applied to the captured image for identification of the bone fragments contained in the image. Thereafter, a fragment-matching algorithm is executed on the segmented bone fragments for calculation of result data. The result data includes instruction data for assembling at least a part of the bone fragments, which is output on the monitor in a configurable format.

First claim

The invention claimed is:

1. A method for calculation and output of result data based on at least one medical image that has been captured by an imaging device, the method comprising:
acquiring at least one image with a plurality of bone fragments in a digital format, the acquiring comprising carrying out a medical imaging method using the imaging device;
identifying, by a processor, the plurality of bone fragments contained in the at least one acquired image, the identifying comprising using a segmentation method based on the at least one acquired image to provide segmented bone fragments, and verifying the segmentation method by accessing a database in which anatomical structures and part structures are stored, wherein the anatomical structures and the part structures are automatically assignable, by a mapping, to the segmented bone fragments;
calculating, by the processor, result data that includes instruction data for assembling at least a portion of bone fragments of the plurality of bone fragments, the calculating comprising fragment-matching the plurality of bone fragments; and
outputting the result data in a configurable format.

2. The method of claim 1 , wherein the fragment-matching is based on an automatic recognition of geometrical shapes.

3. The method of claim 1 , wherein the fragment-matching is based on pattern recognition.

4. The method of claim 3 , wherein the pattern recognition comprises curve-matching.

5. The method of claim 1 , further comprising detecting a matching threshold value that specifies a degree of matching between the plurality of bone fragments.

6. The method of claim 1 , further comprising successively expanding the database, the successively expanding comprising automatically storing all captured images, segmented bone fragments, result data, feedback data, or any combination thereof in the database.

7. The method of claim 1 , further comprising recalculating the at least one acquired image, the recalculating comprising executing an image processing measure to base the fragment-matching on the at least one image.

8. The method of claim 1 , further comprising displaying, by a monitor, the result data.

9. The method of claim 1 , further comprising:
detecting a position of a surgical device; and
outputting a signal as the instruction data to provide guidance for movement of the surgical device based on the detected position.

10. A controller configured to calculate and display of result data based on at least one medical image that has been captured by an imaging device in a digital format, a plurality of bone fragments being displayed in the at least one captured medical image, wherein the controller is configured to:
segment the at least one captured medical image for identification of the plurality of bone fragments contained in the at least one medical image to provide segmented bone fragments;
access a database having anatomical structures and part structures, wherein the anatomical structures and the part structures are automatically assignable, by a mapping, to the segmented bone fragments;
calculate result data, the calculation of the result data comprising fragment-matching the plurality of segmented bone fragments, the result data comprising instruction data for assembling at least a part of the bone fragments; and
exchange data with an output unit configured to output the result data in a configurable format.

11. In a non-transitory computer-readable storage medium that stores instructions executable by a digital computer to calculate and output result data based on at least one medical image that has been captured by an imaging device, the instructions comprising:
acquiring at least one image with a plurality of bone fragments in a digital format, the acquiring comprising carrying out a medical imaging method using the imaging device;
identifying, by a processor, the plurality of bone fragments contained in the at least one acquired image, the identifying comprising using a segmentation method based on the at least one acquired image to provide segmented bone fragments, and verifying the segmentation method by accessing a database in which anatomical structures and part structures are stored, wherein the anatomical structures and the part structures are automatically assignable, by a mapping, to the segmented bone fragments;
calculating, by the processor, result data that includes instruction data for assembling at least a part of the plurality of bone fragments, the calculating comprising fragment-matching the plurality of bone fragments; and
outputting the result data in a configurable format.

12. The non-transitory computer-readable storage medium of claim 11 , wherein the fragment-matching is based on an automatic recognition of geometrical shapes.

13. The non-transitory computer-readable storage medium of claim 11 , wherein the fragment-matching is based on pattern recognition.

14. The non-transitory computer-readable storage medium of claim 13 , wherein the pattern recognition comprises curve-matching.

15. The non-transitory computer-readable storage medium of claim 11 , further comprising:
detecting a matching threshold value that specifies a degree of matching between the plurality of bone fragments.
