Method for recording and processing measurement data from a hybrid imaging device and hybrid imaging device

摘要

A method is disclosed for recording and processing measurement data from a hybrid imaging device including a first partial device for a first imaging modality and a second partial device for emission tomography. In at least one embodiment, the method includes: performance of measurement data recording with the first partial device, wherein successive different table positions are approached during the measurement data recording; recording of emission tomography measurement data with the second partial device during the performance of the measurement data recording with the first partial device at the different table positions; assignment of the recorded emission tomography measurement data to the different table positions; changing of the emission tomography measurement data assigned to different table positions with respect to the data volume in such a way that the recording times corresponding to the changed data volumes are matched to each other at different table positions; and reconstruction of an emission tomography image from the changed emission tomography measurement data. At least one embodiment of the invention further relates to a hybrid imaging device designed to perform the method.

1. A method for recording and processing measurement data from a hybrid imaging device including a first partial device for a first imaging modality and a second partial device for emission tomography, said method comprising:
first performing measurement data recording with the first partial device, wherein successive different table positions associated with recording times, respectively, are approached during the measurement data recording; recording emission tomography measurement data with the second partial device during the performing of the measurement data recording with the first partial device at the different table positions; assigning the recorded emission tomography measurement data to data sets, each data set containing emission tomography measurement data recorded at one of the different table positions, a volume of emission tomography measurement data in each of the data sets being correlated to the recording time at the respective table position; determining, for each data set, at least one of a recording time at the respective table position and the volume of emission tomography measurement data in the data set; changing the volume of emission tomography measurement data in at least one of the data sets by at least one of increasing and reducing the volume of recorded emission tomography data in the at least one data set such that the recording times correlated to the volume of emission tomography measurement data in the data sets are greater than threshold recording times, respectively; and reconstructing an emission tomography image from the changed emission tomography measurement data.
