Abstract

A medical technology facility includes a functional component, a carrier arrangement provided so as to position the functional component in a space, at least one additional component configured to be positioned and/or formed differently in different positions of the carrier arrangement, and a control facility. In order to form a collision protection system, the control facility is configured to: update a digital movement model of the medical technology facility, wherein the digital movement model maps the carrier components and the functional component with their movability based on position data that indicates prevailing positions of the carrier components; evaluate the prevailing movement model so as to detect possibly impending collisions with at least one subject and/or object that is located in the movement region and that is mapped in the movement model; and implement at least one collision protection measure when an impending collision is detected.

First claim

The invention claimed is:

1. A medical technology facility comprising:
at least one functional component;
a carrier arrangement configured to position the functional component in a space, wherein the carrier arrangement comprises at least two carrier components configured to be moved relative to one another;
at least one additional component positioned and/or formed differently in different positions of the carrier arrangement; and
a control facility configured to form a collision protection system, wherein the control facility comprises:
a modelling unit configured to update a digital movement model of the medical technology facility, wherein the digital movement model maps the at least two carrier components and the at least one functional component with a movability of the at least two carrier components and the at least one functional component based on position data that indicates prevailing positions of the at least two carrier components;
a detection unit configured to evaluate the digital movement model so as to detect possibly impending collisions with at least one subject and/or object that is located in a movement region and mapped in the digital movement model; and
an intervention unit configured to implement at least one collision protection measure when a possibly impending collision is detected,
wherein the digital movement model also maps a movement of the at least one additional component,
wherein the modelling unit is configured to determine additional data that describes a prevailing pose and/or a shape of the at least one additional component from a relationship of at least one part of the position data with the additional data, and
wherein the relationship is stored in the control facility.

2. The medical technology facility of claim 1 , wherein the at least one additional component comprises at least one element of a cable routing component for at least one cable.

3. The medical technology facility of claim 2 , wherein the at least one element of the cable routing component comprises at least one rigid cable outlet, in particular for connecting to a grooved hose.

4. The medical technology facility of claim 1 , wherein the additional component is added to the digital movement model that uses at least one kinematic chain in Denavit-Hartenberg notation, in particular as a rigid, rotatably coupled kinematic element.

5. The medical technology facility of claim 4 , wherein the additional data describes an angular position of the at least one kinematic chain.

6. The medical technology facility of claim 1 , wherein the medical technology facility is an X-ray facility comprising a recording arrangement as a functional component, which comprises an X-ray emitter and an X-ray detector.

7. The medical technology facility of claim 6 , wherein at least one carrier component of the at least two carrier components of the carrier arrangement is a C-arm that is guided in a displaceable manner in an outer arm via a holder as a further carrier component,
wherein a position of the C-arm with respect to the holder is described in the position data by a position angle,
wherein the relationship for an element, in particular a cable outlet, of a cable from the holder to a cable routing component, which as an additional component guides the functional component and, arranged on the C-arm, allocates the additional data to the position angle.

8. The medical technology facility of claim 7 , wherein the cable routing component is fastened to the C-arm and the holder, and
wherein the additional data describes an angular position of a respective cable outlets as additional components to a respective carrier component of the at least two carrier components.

9. The medical technology facility of claim 1 , wherein the relationship is configured to be stored as a look-up table, and
wherein the modelling unit is configured to determine by interpolation additional data for values of the position data that lie between values in the look-up table.

10. The medical technology facility of claim 1 , further comprising:
at least one encoder allocated to an actuator,
wherein the at least one encoder is configured to determine at least one part of the position data.

11. The medical technology facility of claim 1 , wherein the detection unit is configured to use as a subject at least one patient, in particular who is at least in part modelled as cylindrical, and/or to use as an object a patient table that in particular forms a part of the medical technology facility.

12. A computer-implemented method for operating a medical technology facility having at least one functional component, a carrier arrangement that positions the at least one functional component in a space and comprises at least two carrier components configured to be moved relative to one another, and at least one additional component positioned and/or formed differently in different positions of the carrier arrangement, the computer-implemented method comprising:
updating, by a control facility of the medical technology facility, a digital movement model of the medical technology facility using position data that indicates prevailing positions of the at least two carrier components of the carrier arrangement, wherein the digital movement model maps the at least two carrier components and the at least one functional component with a movability of the at least two carrier components and the at least one functional component;
evaluating, by the control facility, the digital movement model so as to detect a possibly impending collision with at least one subject and/or object that is located in a movement region and mapped in the digital movement model; and
performing, by the control facility, at least one collision protection measure when the possibly impending collision is detected,
wherein the digital movement model also maps a movement of the at least one additional component, wherein additional data that describes a prevailing pose and/or a shape of the at least one additional component is determined from a relationship, which is stored in the control facility, of at least one part of the position data with the additional data.

13. A computer program that, when executed on a control facility, is configured to:
update a digital movement model of a medical technology facility using position data that indicates prevailing positions of at least two carrier components of a carrier arrangement of the medical technology facility, wherein the digital movement model maps the at least two carrier components and at least one functional component of the medical technology facility with a movability of the at least two carrier components and the at least one functional component;

perform at least one collision protection measure when the possibly impending collision is detected,
wherein the digital movement model also maps a movement of at least one additional component, wherein additional data that describes a prevailing pose and/or a shape of the at least one additional component is determined from a relationship, which is stored in the control facility, of at least one part of the position data with the additional data.
