ABSTRACT:
A method is disclosed 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. In at least one embodiment, the method includes a positron-emission measurement being carried out in the body area to be examined of the examination object in order to determine functional positron-emission measurement information, and recording, at the same time as the positron-emission measurement, anatomical measurement information about the body area to be examined is recorded, restricted to one recording plane, for at least one measurement time period, using an anatomical imaging method with high time resolution, in particular using a computed-tomography method. Thereafter, a complete four-dimensional data record of anatomical reference measurement information is recorded for at least one period of a movement process with high time resolution using the anatomical imaging method, and the positron-emission measurement information from the measurement time period is associated 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, from the anatomical imaging method using the four-dimensional anatomical reference measurement information.
