A computer-implemented method is for determining at least one main acquisition parameter determining a dose of x-rays to be emitted from an x-ray emitter during image acquisition using an x-ray emitter and an x-ray detector. A first image data of a first preparatory image is evaluated to determine if a repeat condition is fulfilled and/or to determine the main acquisition parameter and/or at least one second preparatory acquisition parameter. The first preparatory image is acquired by the x-ray detector using at least one first preparatory acquisition parameter to control the x-ray emitter. In all cases or when the repeat condition is fulfilled, the main acquisition parameter is determined depending on second image data of a second preparatory image, acquired by the x-ray detector after the first preparatory image while at least one second preparatory acquisition parameter is used to control the x-ray emitter.

Computer-implemented method for determining at least one main acquisition parameter and method for acquiring a main x-ray image

A method is for positioning an imaging-relevant component of an imaging apparatus in an application-appropriate position for recording medical image data from a target region of a patient. In an embodiment, the method includes: acquiring information on the target region of the patient, acquiring a position of the patient relative to the imaging-relevant component, determining an application-appropriate position of the imaging-relevant component, determining a positioning instruction, and outputting the positioning instruction. An imaging apparatus of an embodiment includes an imaging-relevant component. The imaging-relevant component has a mechanical guide configured to position the imaging-relevant component along at least one degree of freedom of movement relative to a static arrangement of the imaging apparatus and/or a patient.

A method and system are disclosed for outputting augmented reality information to a first user. In an embodiment, the method includes acquiring first information, including image information, depth information, coordinate information and combinations thereof, the first information relating to at least one of a medical device and a medical examination of a patient; creating the augmented reality information, relating to the medical device and/or the medical examination of the patient, based on the first information; and outputting the augmented reality information such that the augmented reality information is perceivable in a field of view of the first user.

Method and system for outputting augmented reality information

A method and a device are disclosed for controlling a scanning region of a medical imaging system for subsequent recording of a region of interest of an examination object. Depth image data of the examination object are captured. 2-D image data of at least one 2-D image of the examination object are created and the 2-D image is displayed. The 2-D image data and the depth image data of the examination object are registered to each other at least in some regions. By using the 2-D image, at least one limit position of the scanning region is then determined. Finally, on the basis of the depth image data and the limit position in the 2-D image of the examination object, a limit contour line extending through the limit position is determined and displayed such that the limit contour line is superimposed on the 2-D image of the examination object.

Control of the positioning of a scanning region of a medical imaging system

A method is for displaying position information relating to a position of a region of interest of a patient relative to an examination unit of an imaging apparatus. A first examination plane is assignable to the examination unit and a camera is disposed relative to the examination unit such that, via a lens of the camera, three non-collinear reference points lying in a first reference plane parallel to the first examination plane are mapped to three collinear first image points lying on a first line. In an embodiment, the method includes capturing a camera image of the region of interest via the camera; displaying a positioning image, the positioning image including the camera image; and displaying first marking information relating to a position of the first line in the positioning image.

A method and a device are disclosed for the perspective representation, via an output image, of at least one virtual scene component arranged within a real scene. In the method, depth image data of the real scene is captured from a first perspective via a depth image sensor, and 2D image data of the real scene is captured from a second perspective via a 2D camera. Further, a virtual three-dimensional scene model of the real scene is created with reference to depth information from the depth image data, and at least one virtual scene component is inserted into the three-dimensional virtual model. Finally, an output image is generated by way of perspective projection of the 2D image data corresponding to the second perspective onto the virtual three-dimensional scene model comprising the virtual scene component.

The automated positioning of an examination table relative to a medical-technical imaging installation is provided. A camera image is frozen by a first user interaction. Reference information is defined in the frozen camera image by a second user interaction. An examination table or medical-technical imaging installation with the aid of a positioning system is moved based on congruence between the reference location information with a recording region of the medical-technical imaging installation.

A method and a device are for determining the rotation angle of a rotor-stator device. The rotor-stator device has a slip ring arrangement for transferring data between rotor and stator. In an embodiment, the device includes a signal conductor, essentially ring-shaped or ring-segment-shaped, fixed to a ring-shaped support structure; a transmitter for injecting a data signal into the signal conductor; and a receiver for reading the data signal out from the signal conductor. The transmitter and receiver move in opposite directions synchronously with the rotation between rotor and stator. According to an embodiment of the method, a signal is injected into the signal conductor. The signal is used to generate a metrologically detectable characteristic from which the rotation angle is ascertained.

A medical device is controlled as a function of a position of a control element projected onto a projection surface, wherein a geometric property of the projected control element is adjusted to the surface structure. The adjustment is accomplished by means of a transformation of projection data, the projection data corresponding to the control element that is to be projected. The optical projection of the control element is based on the transformed projection data. Such an adjustment and transformation are made possible by determining the surface structure of the projection surface. The control system has an image processor both for determining the surface structure and for transforming the projection data. The control system additionally has a projector for optically projecting the control element and a control unit for controlling the medical device based on the first position of the projected control element.
