摘要： In a method and a computer for identifying a group of persons, from a number of persons, to whom at least one contrast agent has been applied during an examination which was carried out in an imaging system with which medical images of each of the number of persons were produced, existing examination data provided for each of the number of persons are used to determine to which of those persons the at least one contrast agent was applied. The persons to whom at least one contrast agent was applied during the examination are identified as a group of persons. For each person in the group, person-specific contrast agent data are determined that include at least identification information identifying the person to whom the at least one contrast agent was applied, and contrast agent information identifying the fact that the at least one contrast agent was applied. A designation of each person in the group of persons is stored with that person's corresponding person-specific contrast agent data in a register.

摘要： In a method and apparatus for determining measurement protocol parameters of a magnetic resonance (MR) image, a first MR image exhibiting first contrast properties, is read into a computer and at least one first contrast ratio is determined in the computer from the first contrast properties. The computer then determines the measurement protocol parameters dependent on the at least one first contrast ratio, in order to generate a second MR image exhibiting second contrast properties such that the second contrast properties approximate, as closely as possible, to the first contrast properties. The measurement protocol parameters are presented as an output from the computer.

摘要： In a method and computer for the representation of magnetic resonance data, and a method and computer for storing magnetic resonance data in a computer, magnetic resonance data are acquired from an object under investigation, the acquired data represents a spatially resolved distribution of values of a number of tissue parameters in the object. A tree structure is created that has a trunk and a number of first tree elements branching from the trunk. A first tissue parameter among the multiple tissue parameters is assigned to the trunk and a second tissue parameter among the multiple tissue parameters is assigned to the number of first tree elements. The tree structure with respect to the acquired values of the multiple tissue parameters, so an adapted tree structure is compiled. The adapted tree structure is presented for a user on a display monitor.

摘要： In a method for displaying quantitative magnetic resonance image data, and a processor, and a magnetic resonance (MR) apparatus that implement such a method, first quantitative MR image data of an examination object are provided to the processor, the first quantitative MR image having been obtained using an MR scanner with a first basic magnetic field strength. The first quantitative magnetic resonance image data are converted in the processor from the first basic magnetic field strength to a second basic magnetic field strength, thereby generating second quantitative MR image data, which are then displayed.

摘要： Sterile RF coil arrangements for use in magnetic resonance imaging are provided. The sterile coil arrangements can be formed by spraying or coating a curable liquid onto an RF coil housing and allowing the liquid to cure or dry to form a continuous sterile layer on the coil housing. The thickness of the sterile layer can be between 100 and 1000 micrometers. The curable liquid can include an antimicrobial or antibacterial agent, such as silver ions or triclosan, to better maintain sterility of the coil arrangement. The curable liquid can be selected such that it adheres to the housing when cured and is also removable without leaving residue behind.

摘要： In a magnetic resonance (MR) apparatus and a method for operation thereof, the radio-frequency (RF) resonator of the scanner of the apparatus fed from a single RF source and is operated, during a total scan duration for acquiring MR scan data from a subject, so as to excite nuclear spins in the subject with respective RF fields having different B1+ field profiles that are radiated at respectively different times during the acquisition of the scan data. The scan data acquired during the scan thus are produced from MR signals caused by nuclear spins excited by at least two different B1+ field profiles. The scan can be used to acquire MR data for MR fingerprinting.

摘要： A magnetic resonance system that is designed to carry out an examination of an examination object, and has an RF controller, a gradient controller and an image sequence controller, which are designed to acquire MR data of a volume portion of the examination object. An arithmetic unit of the magnetic resonance system is designed to reconstruct MR images from the acquired MR data. A standardized REST-based HTTP radio interface of the magnetic resonance system is designed to establish a standardized wireless connection to at least one external device.

摘要： A system for generating medical image scanner configurations includes a scanner configuration database and a simulation component. The database stores a scanner configuration dataset corresponding to a medical image scanner. The simulation component includes a display module which is configured to present a graphical user interface (GUI) utilized by the medical image scanner, and an editing module which is configured to create a modified scanner configuration dataset based on commands received from a user via the GUI. Additionally, the simulation component includes a simulation module which is configured to (i) perform a simulation of the medical image scanner using the modified scanner configuration dataset to yield simulated results, (ii) use the display module to present the simulated results in the GUI, and (iii) in response to receiving user approval of the simulated results via the GUI, save the modified scanner configuration dataset to the database.

摘要： Techniques are described for providing image-based operational decision support. The technique includes providing initial imaging data from a preceding examination of a patient, determining clinical findings by automated processing of the initial imaging data, generating decision data at least comprising a decision whether a further recording of a number of images is necessary, and generating a suggested set of imaging parameter values for recording this number of images. The decision data may be based on the determined clinical findings, and the technique may further include outputting the suggested set of imaging parameter values for recording a number of images of the patient. Also described are a related clinical decision system, a decision module, and a related medical imaging system.
