Abstract: A host device (300) provides wireless docking to a dockee device (250). The host has a remote client unit (210) for providing at least one audio/video (AV) rendering function to an application (252) via remote server unit (251) in a dockee device. The host has transfer units (211,212,213,214) arranged for enabling transmitting a downstream of first AV data to the dockee device, and receiving an upstream of second AV data to be rendered from the dockee device. The host device has an AV router (310) for processing the downstream and the upstream so as to replace first AV data in the downstream by a predetermined pattern before transmitting the downstream to the dockee device, and replace at least part of second AV data in the upstream by at least part of the first AV data after receiving the upstream from the dockee device and before rendering the AV data. Advantageously required bandwidth is reduced in the wireless communication.

Abstract: An imaging system (36) includes a Positron Emission Tomography (PET) scanner (38) and one or more processors (52). The Positron Emission Tomography (PET) scanner (38) which generates event data including true coincident events and scatter events, the event data includes each end point of a line of response (LOR) and an energy of each end point. The one or more processors (52) are programmed to generate (72) a plurality of activity map and attenuation map pairs based on the true coincident events, and select (76) an activity map and an attenuation map from the plurality of activity and attenuation map pairs based on the scattered events.
