Abstract: The invention relates to a medical diagnostic device comprising an operating element for controlling system components of the medical diagnostic device, said device comprising at least one operating lever which is embodied in such a way that it has at least one feature which is characteristic of the associated system component and is, for example, designed in such a way that it is congruent to the system component. In this way, the operating lever has a form adapted to that of the real system components or has the same form as said components.

Abstract: A user is provided with an analytical function which indicates an individual contribution of each search term used in a complex search query by a graphical, typographical or numerical indicator. For this purpose there is started in the background for each search term a search query which consists of the complex search query without the respective search term. The hit count obtained in this way is subtracted from the total hit count of the search query with the respective search term. The difference is a numerical indicator for the individual contribution of the respective search term to the total hit count. Thus, the user quickly and conveniently obtains a reference point indicating which search terms are crucial to the search query. The user can thus selectively refine the search query by explicitly specifying less significant search terms or removing overly restrictive search terms.

Abstract: The invention relates to a medical system with a medical device, especially an x-ray, a C-arm x-ray, a computer tomograph, a magnetic resonance tomograph or an ultrasound tomograph. The medical device features a control input for receiving a control signal and can be controlled as a function of the control signal. The medical system also features a user interface with a control facility to allow control by a user. The control facility is, depending on a movement of the control element, for generating the control signal. The user interface features a selection facility and at least two facility interfaces being effectively connected to the selection facility. The facility interfaces are each for connection to a control input of the at least two medical devices. The selection facility is for connecting the control facility to at least one or precisely one facility interface.
