    摘要: A method of delivering a radioactive liquid includes, performing an initialization, including; extracting at least a first amount of a radioactive liquid from a source of radioactive liquid, measuring a radioactivity level for the first amount of radioactive liquid, and performing a calibration phase. The calibration phase includes, extracting a second amount of radioactive liquid from the source of radioactive liquid wherein the second amount is calculated based on the radioactivity level of the first amount to provide a total dose of radioactive liquid having a predetermined radioactivity level, and delivering the total dose and performing at least one more calibration and delivery phases.

    摘要: A device and a method for accurate dispensing of a radioactive liquid are disclosed. A source of a radioactive liquid and a source of a flushing liquid are selectively connected to a fluid delivery path by way of valve means. An activity metering unit is operable to determine a level of radioactivity in a metering section of the fluid delivery path downstream from the valve means. The device is operated by transporting a first amount of radioactive liquid to the metering section, using the activity metering unit to measure a reference level of radioactivity, calculating a second amount of the radioactive liquid still to be delivered such that the first and second amounts of radioactive liquid together have some predetermined level of radioactivity, and delivering the first and second amounts of radioactive liquid to the destination.
