The system can include a distributed database system which configured to receive configuration protocols from the device host and to store modified configuration protocols for the respective device host, and to distribute modified configuration protocols. The received and/or stored configuration protocols are made available via a central write access. The system can include an administrator having a memory, a user interface and a processor for communicating with the distributed database system. Configuration protocols can be modified via the user interface and sent to the distributed database system for storage and/or distribution to at least one selected imaging device. These aspects are also applicable to a method for the administration of imaging devices.

Abstract: In a medical imaging apparatus and method for operation thereof, data acquisition protocols are stored, each containing data acquisition parameters of the medical imaging apparatus that define a data acquisition operation. In the event of an update, which changes the possible setting scope for data acquisition parameters, of at least one software and/or hardware component of the medical imaging apparatus to a current equipment version, and/or in the event of the input of a data acquisition protocol not defined for the current equipment version, a set of rules is applied to all protocols not defined for the current equipment version. The rules include at least one adaptation rule for at least one data acquisition parameter, which rule, when applicable, increases at least one quality measure for image data recorded using the data acquisition protocol to which the adaptation rule is applied.

Abstract: In a computer-supported method for processing an examination step, which includes parameters that can be set for imaging with a magnetic resonance apparatus, permitted ranges of values of the parameters are defined by a configuration of the magnetic resonance apparatus, and the configuration is described by a configuration file. An editor is functionally connected to the processor that performs a selection step. The selection step will be supplied with different configuration files, which describe different configurations of magnetic resonance apparatuses. After a selection made by a user from the different configuration files, this file will be supplied as the selected configuration file to the editor.

Abstract: Systems and methods are provided for comparing a system configuration of a magnetic resonance tomography unit. The magnetic resonance tomography unit includes a controller and an output unit. The configuration device includes a controller and an input unit. A data storage device includes a data connection with the magnetic resonance tomography unit via a first data link and with the configuration device via a second data link. A first system configuration of the magnetic resonance tomography unit is stored on the data storage device. The magnetic resonance tomography unit generates an identification for the first system configuration and outputs the identification. The configuration device detects the identification with the input unit and accesses the first system configuration in the data storage device using the identification.

Abstract: In a method and magnetic resonance (MR) apparatus for establishing implant information about a patient based on an MR scan of the patient, the MR scan is performed by implant-safe settings in the control parameters. The MR signals acquired in this scan are reconstructed to produce image data, and the image data are searched for at least one weak-signal region in a computer search. Implant information about the patient are generated by the computer dependent on the result of the search for the at least one weak-signal region, and the implant information is made available as an electronic output from the computer.

Abstract: An operating method for a medical imaging apparatus includes an imaging program stored in a memory, with which parameters for controlling image data generation will be predetermined. The imaging program has a number of routine examination steps. At least one variant, which is likewise stored in the memory and which is able to be selected by a user instead of the routine examination step for image data generation, exists at least for one of the routine examination steps.

Abstract: In a method for determining an acceleration factor of a parallel image acquisition for a data acquisition direction of a measurement volume by means of a magnetic resonance device having multiple coil units, each coil unit emits at least one output signal for parallel image acquisition and wherein an acceleration contribution is assigned for at least one direction (X,Y,Z) for a sensitive volume. Relevant coil units, which by virtue of the arrangement of their sensitive volume in relation to the measurement volume contribute to the acceleration, are specified. The data acquisition direction in the measurement volume is specified and the acceleration factor in this direction is determined by means of acceleration contributions depending on the position of the relevant coil units with respect to one another and the position of the relevant coil units in relation to the measurement volume and to the data acquisition direction.
