Method and device for accurate dispensing of radioactivity

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.

1. A method of delivering a radioactive liquid, comprising:
performing an initialization, comprising:
extracting an offset amount of a radioactive liquid from a source of radioactive liquid;adjusting a first valve means connected between at least the source of radioactive liquid, a flushing liquid source, and a fluid delivery path; andtransporting the offset amount of the radioactive liquid to a downstream portion of the fluid delivery path by pumping a flushing liquid from the flushing liquid source through the fluid delivery path; performing a calibration phase, comprising:
extracting a first amount of radioactive liquid from the source of radioactive liquid;determining a radioactivity level for the first amount of radioactive liquid; andextracting a second amount of radioactive liquid from the source of radioactive liquid wherein the second amount is calculated based on the radioactivity level for the first amount to provide a total dose of radioactive liquid having a predetermined radioactivity level; delivering the total dose of radioactive liquid; and performing at least one more calibration and delivery phases.
