- W1507384906 abstract "We are developing an open-type PET geometry that we named OpenPET. One possible geometry is the dual-ring OpenPET, which consists of two detector rings separated by a gap for entrance of the radiation beam. The gap can also be used for different modalities such as X-ray CT to realize a simultaneous multi-modality system. In addition, the dual-ring OpenPET has an effect to enlarge the axial field-of-view. In our previous simulations and experiments the OpenPET imaging geometry was shown to be feasible by applying iterative reconstruction methods. However, the gap violates Orlov's completeness condition for accurate tomographic reconstruction. Therefore, the gap could lead to artifacts caused by lost low-frequency components in the projection data depending on the shapes of imaging subjects. In this study, we investigate the effect of time-of-flight (TOF) information, which is expected to compensate for the lost low-frequency components in OpenPET imaging. We simulated the dual-ring OpenPET geometry with a numerical phantom and analyzed frequency components of the reconstructed images. The result showed that the low-frequency components were not fully estimated in the gap region of the dual-ring OpenPET while those components were well recovered with the TOF information." @default.
