The purpose of this study was to assess the optimal gates number of each region using estimated internal motion. Internal motion has been demonstrated in lung and liver region of small animal by coated molecular sieve. We coated molecular sieve with Pluronic F-127 hydrogel for keeping the activity in the body. All PET studies were performed with a dedicated small animal PET scanner. Respiratory gating...
As a sensor network has a limited node resources and unexpected changes of external environment, its nodes should show energy efficiency, reliable data transmission, and topological adaptation to the change of external environment. However, it is not easy to satisfy these requirements at the same time. This study proposes Robust and Energy efficient Dynamic Single path routing (REDS), a routing mechanism...
