Abstract

A method for actuating an X-ray device during robot-assisted navigation of at least two objects introduced into a body, such as a hollow organ, of a patient by at least one robotic system, includes providing a first selection criterion for selecting one of the objects, and providing a second selection criterion for selecting one of the objects. One of the at least two objects is selected based on the first selection criterion and the second selection criterion, and recording parameters of the X-ray device are automatically set, such that the selected object in an X-ray image to be recorded is highlighted compared to the at least one other object. The selected object may be highlighted with respect to image quality, image flavor, positioning on the X-ray image, and/or a collimator setting of a collimator of the X-ray device. An X-ray image is recorded with the set recording parameters.

First claim

The invention claimed is:

1. A method for actuating an imaging device during robot-assisted navigation of at least two objects introduced into a body of a patient by at least one robotic system, the method comprising:
providing a first selection criterion for selecting an object of the at least two objects;
providing a second selection criterion for selecting the object or another object of the at least two objects;
selecting one object of the at least two objects based on at least the first selection criterion and the second selection criterion;
automatically setting recording parameters of the imaging device, such that the selected one object is highlighted in an image to be recorded; and
recording an image with the automatically set recording parameters.

2. The method of claim 1 , wherein the imaging device is an X-ray device, and the body is a hollow organ.

3. The method of claim 1 , wherein the recording parameters of the imaging device are automatically set, such that the selected one object is highlighted compared to the at least one other object of the at least two objects.

4. The method of claim 3 , wherein the recording parameters of the imaging device are automatically set, such that the selected one object is highlighted compared to the at least one other object of the at least two objects with respect to image quality, image flavor, positioning on an X-ray image, a collimator setting of a collimator of the imaging device, or any combination thereof.

5. The method of claim 1 , wherein one selection criterion of the first selection criterion and the second selection criterion is weighted more than the other selection criterion of the first selection criterion and the second selection criterion.

6. The method of claim 1 , further comprising providing a third selection criterion,
wherein the one object is selected based also on the third selection criterion.

7. The method of claim 6 , wherein the first selection criterion is formed based on an evaluation of at least one recorded image with respect to a structure of interest, or based on an evaluation of an eye tracking system with respect to an object of interest.

8. The method of claim 7 , wherein the third selection criterion is formed based on an evaluation of an eye tracker with respect to an object of interest or based on an evaluation of at least one previously recorded X-ray image with respect to a structure of interest.

9. The method of claim 1 , wherein the second selection criterion is formed based on information from the at least one robotic system as to which object is currently being actuated or moved.

10. The method of claim 1 , wherein the recording parameters are formed by an X-ray voltage, an X-ray dose, an X-ray current, a diaphragm setting, a filter setting, a duration of an X-ray window, an intensity, positioning with respect to the central beam, or any combination thereof.

11. The method of claim 1 , wherein an updated selection of the one object takes place continuously or at regular intervals using at least one selection criterion of the first selection criterion, the second selection criterion, and the third selection criterion, and the recording parameters of the imaging device are set such that the updated selected one object in an image to be recorded is highlighted compared to the at least one other object, and
wherein the method further comprises performing a further recording of an image with the set recording parameters set.

12. The method of claim 1 , wherein the recorded image is postprocessed, and
wherein the one object selected based on the first selection criterion and the second selection criterion is highlighted with respect to image flavor in the course of the postprocessing.

13. A medical system for actuating an imaging device during robot-assisted navigation of at least two objects introduced into a body of a patient by at least one robotic system, the medical system comprising:
an X-ray device operable to record X-ray images, the X-ray device comprising an X-ray source, an X-ray detector, a collimator, and a system controller operable to actuate the X-ray device;
at least one robotic system comprising at least one robot-assisted drive system configured to move at least two medical objects in a cavity organ of a patient;
an evaluation unit configured to evaluate previously recorded X-ray images with respect to a structure of interest;
a communication link between the system controller and the at least one robotic system, the communication link configured to transmit information from the at least one robotic system as to which object of the at least two objects is currently being actuated or moved; and
a selection unit configured to select one of the at least two objects based on selection criteria.

14. The medical system of claim 13 , further comprising:
an eye tracking system configured to track eye movements of an operator; and
a communication link between the system controller and the eye tracking system, the communication link being configured to transmit information with respect to an object of interest.
