Abstract

In high resolution emission tomography imaging, even small patient movements can considerably degrade image quality. This work investigates an approach to motion compensated reconstruction of motion-contaminated data, thus applicable to any scanner in the field (e.g. without list-mode acquisition capability), assuming externally-tracked motion information; it involves incorporation of the measured motion information into the system matrix of the EM algorithm. Furthermore, it is shown that the effect of motion-contamination of the attenuation factors should also be modeled and taken into account in the reconstruction task.
