System for control of positron emission tomography facility (100), comprising a local area network (148) working with the imaging systems (114, 116) for positron emission tomography, is new. The distribution station (106) receives a multi-dose flask (302) of radioactive marker. It distributes doses (126, 128) of the marker to the imaging systems (114). System for control of positron emission tomography facility (100), comprising a local area network (148) working with the imaging systems (114, 116) for positron emission tomography, is new. The distribution station (106) receives a multi-dose flask (302) of radioactive marker. It distributes doses (126, 128) of the marker to the imaging systems (114). The network returns information concerning the state of the imaging systems. It sends instructions to the imaging systems for positron emission tomography, and also to the distribution station (106). An independent claim is included for the corresponding method.
