The invention relates to a mobile medical device, in particular a mobile C-arm X-ray device, comprising a device trolley which can be driven in at least two movement modes in a motor-supported manner, having at least one gripping element, which is provided for gripping by means of at least one human hand of an operator in order to move the device, and additionally having at least one sensor, which is arranged on the gripping element or in the direct vicinity thereof and is designed to detect measurement data that characterizes the type and/or location of the grip by means of the at least one human hand, an evaluating unit, which is designed to evaluate the measurement data with respect to the type and/or location of the grip and assign a movement mode of the device trolley, and a control unit for automatically setting the evaluated movement mode of the device trolley.

Mobile medical device, mobile device, and method

In a method for operation of a docking arrangement, position information is determined that describes a position of the patient table, including detecting, sensor data corresponding to: the position of the patient table relative to the docking arrangement, and/or to an environment feature describing a movement trajectory to the docking arrangement. The method may further include performing, in response to a switchover condition indicative of a handover situation and a purely manual operation of the patient table by an operator, a switch into an assistance operating mode of the docking arrangement. In the assistance operating mode, at least one guidance measure may be determined for the patient table and a functional component of the patient table may be controlled to assist the operator.

A computer-implemented method for generating training data for training an algorithm for estimating positioning variances in an imaging apparatus of an x-ray imaging system is provided. The method includes predetermining target positioning data for the imaging apparatus and calculating faulty positioning data, wherein the faulty positioning data deviates from the target positioning data by at least one predetermined positioning variance. An imaging method is simulated, in order to generate two or more simulated x-ray recordings, wherein a positioning of the imaging apparatus is simulated in accordance with the faulty positioning data. An annotated training data record is generated and stored, wherein the training data record contains two or more simulated x-ray recordings and at least one positioning variance as an annotation of the two or more simulated x-ray recordings.

A method automatically determines a weight of a patient lying on a tabletop of a patient positioning device. A motorized movement of the tabletop along at least one predeterminable axis sets the tabletop in an oscillation via an elastic drive train element, and the patient's weight is determined from a determined oscillation frequency. Therefore, the weight of a patient lying on a patient positioning device can be determined in a simple manner.

An apparatus for movably suspending an x-ray grid. The apparatus has a carrier module, in or on which the x-ray grid is arranged, and a linkage. The linkage is configured to rotate the carrier module about an axis which is vertical to the x-ray grid and/or to translate the carrier module in the plane of the x-ray grid. An x-ray arrangement has an x-ray emitter, an x-ray detector and one or more apparatus for suspending the x-ray grid between the emitter and detector. The apparatus provides for play-free kinematics which is more cost-effective than the use of known precision drives.

A device for suspending an x-ray grid has a first rotating frame which can be rotated about a first axis. The x-ray grid is disposed in or on the rotating frame. Two first flexible hinge elements are connected to the first rotating frame and are aligned along the first axis. The first rotating frame is reversibly rotatable about the first axis. An x-ray arrangement has one or more such suspension devices between an x-ray emitter and an x-ray detector. The articulated flexible elements of the novel device are completely play-free and significantly more cost-effective that separate hinges.

The disclosure provides a device having a C-arm, the C-arm including a main body of which the cross-sectional profile is formed as a double H, an outer wall, an inner wall and two side walls of the main body forming a rectangular cavity. The device also includes running wires arranged on the main body and running rollers, on which the C-arm is movably mounted, rolling on the running wires. The running wires and the running rollers are arranged in such a way that at least 50 percent of the mounting forces acting on the running wires due to the running rollers is introduced into the side walls of the main body. The disclosure also provides an x-ray imager having such a device. The disclosure offers the advantage that undesired oscillations of the C-arm are avoided.

Device having a C-arm and X-ray imager

A C-arm for a medical examination device or therapeutic device, is designed as a cast metal component. In at least one embodiment, one or more reinforcement profile, extending at least in certain sections along the C-arm, are cast in.
