摘要： A computer program product has a check routine and an active part. When the computer program product is called, a computer, while processing the check routine, initiates a transmitter to send a launch signal. A transponder receives this signal, checks whether a time-dependent and/or usage-dependent transmission condition is met and transmits an enable code as warranted. A receiver receives the enable code and communicates it to the computer. The computer checks the enable code and undertakes processing of the active part only when the enable code satisfies an enable condition.

摘要： A method is disclosed for determining positron emission measurement information in the context of positron emission tomography. The method includes carrying out a positron emission measurement, in a body area of a subject to be examined, to record positron emission measurement information with point resolution and determining a time frame of the measurement by, at the same time, generating images of the body area to be examined with a relatively higher time resolution and with point-resolved image data, using a second imaging method. Further, a local shift of points of individual images of the second imaging method is determined, caused by movement processes of the subject to be examined, and as a function thereof, of the positron emission measurement information for at least a part of the measurement period and of the body area to be examined. Finally, the positron emission measurement information is adjusted as a function of the determined shift.

摘要： A positron emission tomography unit (PET), having a unit part assigned to an examination space and a first evaluation unit, is combined with a magnetic resonance tomography unit (MRT). The unit part of the PRT includes at least two gamma ray detector units with in each case an assigned electronics unit. The MRT includes a second evaluation unit, a gradient coil system and a high frequency antenna device formed as a stripline antenna device having at least two conductors. The high frequency antenna device is arranged nearer to the examination space than the gradient coil system with a high frequency shield between the gradient coil system and the high frequency antenna device. Each conductor of the stripline antenna device respectively includes a gamma ray detector unit with an assigned electronics unit. The conductors of the stripline antenna device are configured for the respective gamma ray detector units and their assigned electronics units as shielding covers that are caused by the high frequency antenna device and are opaque to high frequency radiation. An examination object in the examination space can be imaged by the combined positron emission tomography and magnetic resonance tomography unit.

摘要： An additional apparatus for a control device for a magnetic resonance tomography apparatus converts an output signal emitted by the control device from an initial frequency into a second frequency. Magnetic resonance signals are excited by the modified output signal. The excited magnetic resonance signals are received.
