Abstract

Much of the effort in recent years has been directed to the development of algorithms and protocols that address various potential sources of artifact. A practical set of tools has emerged for both acquisition and reconstruction. Foremost in the available techniques has been the development of techniques for the simultaneous acquisition of transmission and emission data with subsequent reconstruction using accelerated maximum likelihood reconstruction. The available of measured transmission data has also aided the development of more rigorous models for scatter and possible techniques for correction of partial volume errors. Acceleration has provided a feasible means for incorporating more rigorous, albeit more complex, models of the emission and detection processes, including distance-dependent resolution and patient motion. In addition, combination of data from anatomical and functional modalities has not only aided in visual identification of clinical features, but also has permitted enhanced reconstruction based on the complementary information.
