Abstract: The present disclosure relates to an imaging system for creating an image of an examination object comprising a system component and a control component. The system component has a component property that is able to assume a value in a first value range established by the imaging system. A corresponding system component of another imaging system comprises a corresponding component property with another value range with an overlap range with the first value range. The control component is embodied to control the use of the system component on the creation of the image, wherein the control component can be operated in a compatibility mode. In the compatibility mode, the control component is configured, on the creation of the image, to only allow values that lie within the overlap range for the component property of the system component.

Abstract: The disclosure relates to a method for operating a medical device, (e.g., an imaging apparatus such as an X-ray device or magnetic resonance tomography unit), and a fault monitoring apparatus for carrying out the method. The fault monitoring apparatus is connected to the medical device via a signal connection. In the method, the fault monitoring apparatus receives an item of status information from the medical device and stores the item of status information in a system state. Further, the fault monitoring apparatus compares the stored system state with a predetermined target state, and, depending on the comparison, releases a function of the medical device, wherein the predetermined target state has a successfully executed function test.

Abstract: A method for operating a medical diagnostic system that is configured to use a system component of the diagnostic system to generate examination data of a person under examination during an examination procedure is provided. The examination procedure with control of the system component is controlled by a piece of control software, and a component driver exchanges control commands of the control software with the system component in order to control the system component. The method includes providing an event driver that communicates with the control software via an interface of the control software. Via the event driver, a first event is detected in the examination procedure and reported to the event driver. When the first event is detected in the examination procedure, the use of the system component in the examination procedure is modified to a first type defined by the event driver.

Abstract: In a magnetic resonance (MR) apparatus and an operating method therefor, a sequence with which the MR data are to be recorded is created in or provided to a control computer of the MR apparatus. A maximum RF output and a maximum gradient performance of the scanner magnetic resonance apparatus during the performance of the sequence are determined by simulating or analyzing the performance of the sequence in the control computer, and it is verified whether the maximum RF output and/or the maximum gradient performance violate predetermined limit values. Execution of the sequence to record the MR data is performed only if the verification showed that the limit values are not violated.
