Abstract

The present invention relates to a system (1) for determining a functional property of a moving object (2), wherein the system (1) comprises a tag (3) contactable to the object (2) such that the tag (3) follows the movement of the object (2) and movement determination device (4) for determining the movement of the tag (3). The system (1) comprises further a functional property determination device (5) for determining a functional property of the object (2) from the determined movement of the tag (3).

Claims

1. A system for determining a functional property of a moving object (2), the system comprising:

a tag (3) contactable to the object (2) such that the tag (3) follows the movement of the object (2),

a movement determination device (4) for determining the movement of the tag (3),

a functional property determination device (5) for determining a functional property of the object (2) from the determined movement of the tag (3).

2. The system as defined in claim 1, wherein the functional property determination device (5) is adapted for determining a movement of the object (2) from the determined movement of the tag (3) and for determining the functional property of the object (2) from the determined movement of the object (2).

3. The system as defined in claim 1, wherein the moving object is a first object (2) within a second object (17), wherein the tag (3) is insertable into the second object (2) for contacting the tag (3) to the first object (2) such that it follows the movement of the first object (2).

4. The system as defined in claim 3, wherein the moving object (2) is a moving heart, wherein at least one first tag (3) is contactable to the right chamber (15) of the heart, wherein at least one second tag (3) is contactable to the left chamber (16) of the heart, wherein the movement determination device (4) is adapted for determining a movement of the at least one first tag (3) and of the at least one second tag (3).

5. The system as defined in claim 4, wherein the functional property determination device (4) is adapted for determining a degree of synchrony between the movement of the right chamber (15) and the left chamber (15) of the heart from the determined movement of the at least one first tag (3) and the at least one second tag (3).

6. The system as defined in claim 4, wherein the functional property determination device (4) is adapted for determining a cardiac output from the determined movement of the at least one first tag (3) and the at least one second tag (3).

7. The system as defined in claim 1, wherein the system comprises a movement influencing element for influencing the movement of the object (2).

8. The system as defined in claim 7, wherein the system further comprises an adaptation device (11) for adapting the moving influencing element such that the determined functional property of the object (2) is maximized.

9. The system as defined in claim 7, wherein the system further comprises a positioning device (12) for positioning the moving influencing element such that the determined functional property of the object (2) is maximized.

10. The system as defined in claim 7, wherein the movement influencing element is changeable at least between a first influencing condition and a second influencing condition, wherein the movement determination device and the movement influencing elements are controllable such that a first movement of the tag (3) is determined if the movement influencing element is in the first influencing condition and that a second movement of the tag (3) is determined if the movement influencing element is in the second influencing condition, and wherein the functional property determination device (4) is controllable such that the functional property is determined at least twice, one time from the first movement of the tag (3) and another time from the second movement of the tag (3), in order to determine the influence of the movement influencing element on the functional property of the object (2).

11. The system as defined in claim 1, wherein the system comprises a visualization unit (13) for visualizing the determined functional property of the object (2) simultaneously with an visualization of the tag (3).

13. A computer program for determining a functional property of a moving object, comprising program code means for causing a system as defined in claim 1 to carry out the steps of the method as defined in claim 12, when the computer program is run on a computer controlling the system.

12. A method for determining a functional property of a moving object (2), the method comprising:

providing a tag (3) contacted to the object (2) such that the tag (3) follows the movement of the object (2),

determining the movement of the tag (3),

determining a functional property from the determined movement of the tag (3).
