  • Publication number: 20180067177
    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.

  • Publication number: 20170322278
    Abstract: In a method for generating a measurement protocol for medical imaging of an object under examination, measurement parameters of the measurement protocol are divided into a protocol structure with a base class and classes supplementing the base class. The base class includes only hardware-independent measurement parameters and the supplementary classes includes only hardware-specific measurement parameters. A method for transferring a measurement protocol, a measurement protocol generation computer, a measurement protocol conversion apparatus, and a medical imaging system make use of such a measurement protocol.

  • Patent number: 8347785
    Abstract: A web offset press includes several printing units through which a web passes essentially in a horizontal direction. The printed web then passes to at least one first folding unit. Each of the printing units has at least one plate cylinder and one transfer cylinder which interacts with the web being printed. An effective plate width of the plate cylinder corresponds to the print image of at least eight upright or prone printed pages in a BIN 4A format. The printed web is slit longitudinally into a plurality of web strands: A first number of these web strands are supplied to the first folding apparatus. At the same time, a second number of web strands, produced by the slitting of the same web, are supplied to a second folding apparatus for further processing.

  • Patent number: 7673513
    Abstract: The invention relates to a sensor device for monitoring accelerations to which an object is subjected. In order to detect whether a value has exceeded or is below a threshold for the acceleration to which objects have been subjected in the past, i.e. without having visual contact with the sensor, the inventive sensor device includes an acceleration sensor, which is permanently linked to the object to be monitored, so that a relative movement between the acceleration sensor and the object is prevented, and an RFID transceiver for non-contact coupling of electrical energy into the acceleration sensor and for sending out radio signals as a function of the physical state of the acceleration sensor.

  • Patent number: 7609854
    Abstract: In a method for representation of medical image information on a display medium an image representation parameter is varied dependent on the position of the observer. Superimpositions of data sets from different medical examinations are thereby displayed. The observer thus has simultaneous access to information from the medical examinations, which makes the diagnosis easier for him or her.

  • Patent number: 7474877
    Abstract: In a method for monitoring a radio-frequency power amplifier, and a radio-frequency device, and a radio-frequency monitoring device and a magnetic resonance tomography system, radio-frequency pulses are emitted at temporal intervals by the radio-frequency power amplifier, and measurement values that represent the power of the radio-frequency pulses are measured at temporal intervals. The measurement values are respectively loaded with a measurement error. Control values are respectively formed based on the sum of a number of measurement values loaded with measurement errors, and the radio-frequency power amplifier is limited in operation if and when a control value reaches or exceeds a predetermined limit control value.
