1. A system for dispensing a fluid, comprising:
a peristaltic pump configured to force an aliquot of radiopharmaceutical fluid from a fluid source into a fluid delivery channel; at least one radioactivity sensor configured to measure a sample value of a radioactivity property of the aliquot; a processor in communication with the peristaltic pump and the at least one radioactivity sensor; and a non-transitory, computer-readable storage medium in operable communication with the processor, wherein the computer-readable storage medium contains one or more programming instructions that, when executed, cause the processor to:
receive the sample value of the radioactivity property of the aliquot,receive a source value of the radioactivity property for the fluid source,determine a sample volume of the aliquot based on a comparison of the sample value and the source value,determine a pump coefficient based on the comparison of the sample volume with an expected volume, wherein the pump coefficient being configured to indicate a volume of the radiopharmaceutical fluid forced into the fluid delivery channel per unit, andcontrol operation of the peristaltic pump to dispense a predetermined dose of the radiopharmaceutical fluid based on a comparison of the sample volume with an expected volume, wherein the sample volume of the aliquot is affected by at least one dimensional property of the fluid delivery channel. |
