Abstract:
1. A method for determination of positron-emission measurement information about a body area which is affected by at least one periodic movement process of an examination object during the course of positron-emission tomography, the method comprising: carrying out a positron-emission measurement, in the body area to be examined of the examination object, to determine functional positron-emission measurement information; recording, at the same time as the positron-emission measurement, anatomical measurement information about the body area to be examined, restricted to one recording plane, for a measurement time period, using an anatomical imaging method with high time resolution and the anatomical measurement information not being a complete three-dimensional data record; recording a complete four-dimensional data record of anatomical reference measurement information for at least one period of a movement process with high time resolution using the anatomical imaging method; and associating the positron-emission measurement information from the measurement time period with corresponding anatomical reference measurement information as a function of a comparison of the anatomical measurement information, associated with the measurement time period of the positron-emission measurement and restricted to one recording plane, with the four-dimensional anatomical reference measurement information.
