Abstract

A medical apparatus has a plurality of movable elements that are remotely displaced. A display device receives inputs for positioning the movable elements from a user. A computing device that is coupled to the display device displays a model of the medical apparatus on the display device. The movable elements are displayed in the model in accordance with the received inputs for positioning. In response to a trigger signal of the user for moving the movable elements, the movable elements are driven so as to adopt the displayed position.

First claim

The invention claimed is:

1. A medical imaging apparatus, comprising:
a plurality of movable elements;
a display device and an input device being a touch-sensitive screen configured to receive inputs for positioning said movable elements from a user;
a computing device connected to said display device and configured to receive input commands for positioning said movable elements via said input device, said computing device being configured to display a model of the medical apparatus on said display device, to display said movable elements in the model in accordance with the input commands received from said input device at target positions that are different from actual positions of the movable elements of the medical apparatus and, in response to a trigger signal input by a user, to drive said movable elements of the medical apparatus to adopt a target position as displayed on said display device, wherein an actual movement of said movable elements of the medical apparatus is only begun when the user inputs the trigger signal;
a locating device configured to locate a user or the display device and to provide locating information to said computing device;
said computing device being configured to adapt a perspective of the display on said display device to a position of said display device on a basis of the locating information received from said locating device; and
said computing device being configured to identify in a representation of the model on the touch-sensitive screen those features of the medical apparatus which serve for moving said movable elements and said input device being configured to accept inputs for positioning one of said movable elements only at a correspondingly identified location in the model.

2. The medical apparatus according to claim 1 , comprising a plurality of sensors connected to said computing device and coupled to said movable elements for detecting positions of said movable elements, wherein said computing device is configured to represent simultaneously in the model the detected positions of the movable elements and the positions of the movable elements predefined by the input commands for positioning.

3. The medical apparatus according to claim 1 , wherein said computing device is configured to adapt a perspective view in which the model is represented on said display device on a basis of perspective inputs, and wherein said input device is configured to receive perspective inputs from the user.

4. The medical apparatus according to claim 1 ,
which further comprises a housing; and
wherein one or both of said display device and said input device are releasably mounted to said housing and are coupled to further components of the medical apparatus via a communication connection; and
further comprising a locating device configured to locate said display device and/or the input device; and
wherein said computing device is configured to adapt the representation of the model on the display device to a relative position of said display device and/or of said input device with respect to said housing of the medical apparatus.

5. The medical apparatus according to claim 1 , wherein said computing device is configured to snap said movable elements at predefined engagement positions of an engagement lattice in the representation of the model on said display device on occasion of a movement of the movable elements by the user.

6. The medical apparatus according to claim 5 , wherein said computing device is configured:
to adapt the engagement lattice on a basis of a current position of a respective said movable element on the medical apparatus; and/or
to adapt the engagement lattice on a basis of a list of clinically relevant positions of the respective said movable element.

7. The medical apparatus according to claim 1 , wherein said computing device is configured to store predefined positions for said movable elements, to display the predefined positions to a user via said display device, and to enable the user to select a respective one of the predefined positions via said input device.

8. The medical apparatus according to claim 1 , further comprising movement indicators at said movable elements which, in a case of a movement of said movable elements are driven in each case by said computing device in order to indicate a movement of said movable elements.

9. The medical apparatus according to claim 1 , further comprising collision sensors for said movable elements, said collision sensors being configured to monitor a movement space of said movable elements and to detect objects in the movement space of said movable elements, wherein said computing device is configured, in the representation of the model, to identify a potential collision of a respective said movable element with a detected object and to output a corresponding warning signal.

10. The medical apparatus according to claim 1 , further comprising a camera system configured to record a three-dimensional image of the surroundings of the medical apparatus, wherein said computing device is configured to represent an environment detected by said camera system jointly with the model of the medical apparatus in said display device.

11. A method of controlling a medical imaging apparatus having movable elements selected from the group consisting of a patient table, an X-ray source and a C-arm of an X-ray machine, the method comprising:
displaying a model of the medical imaging apparatus on a touch-sensitive screen, and thereby identifying those features of the medical imaging apparatus in the representation of the model on the touch-sensitive screen which serve for moving the movable elements on the medical imaging apparatus;
receiving inputs for positioning the movable elements entered by a user via the touch-sensitive screen, and thereby only accepting inputs for positioning one of the movable elements only at a correspondingly identified location in the model;
displaying the movable elements in the model at target positions that are different from actual positions of the movable elements of the medical imaging apparatus in accordance with the inputs for positioning received from the user;
locating the user or the touch-sensitive screen relative to the medical imaging device, and adapting a perspective of a display on the screen to a position of the user or the screen; and
in response to a trigger signal of the user for moving the movable elements of the medical imaging apparatus, driving the movable elements of the medical imaging apparatus to cause the movable elements to move from the actual positions of the movable elements and to adopt the displayed position,

wherein an actual movement of the movable elements of the medical imaging apparatus is only begun when the user inputs the trigger signal.

12. The method according to claim 11 , which comprises carrying out one or more of the following steps:
detecting the positions of the movable elements, and simultaneously displaying in the model the detected positions of the movable elements and the positions of the movable elements predefined by the inputs for positioning; and/or
receiving perspective inputs and adapting a perspective in which the model is represented on the display device in accordance with the perspective inputs; and/or
indicating a movement of the movable elements by way of movement indicators on the movable elements; and/or
locating a user of the medical apparatus and adapting a representation of the model on the display device to a relative position of the user with respect to a housing of the medical apparatus.

13. The method according to claim 11 , which comprises:
detecting obj
