Abstract

The invention relates to a system (100) for producing a representation of an object in image data, based on a template coupled to a model of the object, the system comprising a model unit for adapting the model to the object in the image data, and a template unit for adapting the template to the adapted model on the basis of the coupling between the template and the model. The template defines a representation of the object which is simpler to interpret than the model. The template may be arranged to emphasize useful features of the object. The template comprises substantially fewer degrees of freedom and thus can be efficiently adapted to the model. Because the template of the invention is coupled to the model, the position, orientation and/or shape of the template is determined by the model adapted to the object in the image data. Hence, the template is adapted to the image data. The adapted template is capable of representing the object and its individual characteristics, e.g., the shape of the object as well as the position and/or orientation of the object with respect to an external reference system defined, e.g., based on the image data.

Claims

1. A system (100) for producing a representation of an object in image data, based on a template coupled to a model of the object, the system comprising:

a model unit (110) for adapting the model to the object in the image data; and

a template unit (120) for adapting the template to the adapted model on the basis of the coupling between the template and the model.

2. A system (100) as claimed in claim 1, further comprising an image unit (130) for producing an image of the template.

3. A system (100) as claimed in claim 2, wherein the template comprises a first portion and a second portion, and wherein the image unit (130) is arranged for producing a first portion of the image, based on the first portion of the template, using a first visual pattern, and a second portion of the image, based on the second portion of the template, using a second visual pattern.

4. A system (100) as claimed in claim 1, wherein the template is rigid and is movably coupled to the model.

5. A system (100) as claimed in claim 1, wherein the template comprises a plurality of control points which are rigidly or elastically coupled to the model.

6. A system (100) as claimed in claim 1, wherein the template is elastic.

7. A system (100) as claimed in claim 1, wherein the template comprises at least one curve or surface.

8. A reporting system (300) for creating a report, the reporting system (300) comprising the system (100) according to claim 2, the report comprising the image of the template.

9. An image acquisition apparatus (500) comprising a system (100) as claimed in claim 1.

10. A workstation (600) comprising a system (100) as claimed in claim 1.

11. A method (400) of producing a representation of an object in image data, based on a template coupled to a model of the object, the method comprising:

a model step (410) for adapting the model to the object in the image data; and

a template step (420) for adapting the template to the adapted model on the basis of the coupling between the template and the model.

12. A method (400) as claimed in claim 11, further comprising an image step (430) for producing an image of the template.

13. A method (400) as claimed in claim 12, wherein the template comprises a first portion and a second portion, and wherein the image step (430) is arranged for producing a first portion of the image, based on the first portion of the template, using a first visual pattern, and a second portion of the image, based on the second portion of the template, using a second visual pattern.

14. A computer program product to be loaded by a computer arrangement, comprising instructions for producing a representation of an object in image data, based on a template coupled to a model of the object, the computer arrangement comprising a processing unit and a memory, the computer program product, after being loaded, providing said processing unit with the capability to carry out the tasks of:

adapting the model to the object in the image data; and

adapting the template to the adapted model on the basis of the coupling between the template and the model.
